			Jot's second fight of the day was against [[Kamino]], a 4WD vertical spinner. The fight was a short one, with Jot's experimental wheels proving to be a far less durable than anticipated. After just a few hits, the thinner wheels deformed, disabling Jot's ability to drive and leading to a quick tapout loss.
	Coming soon!

			Seeing the new, sandwich-style wheels as a weakness, Morningstar decided to swap Jot's wheels with a set that had been previously made for the June event to avoid similar wheel failures in future matches. Unseen, the motor bell on Jot's JCR-4935 motor had also taken some damage, damage that would not become apparent until later in the event.

			The match ended up being fairly even between the two robots. Damage to the motor bell on Jot's weapon led to weapon spinup being intermittent throughout the match, hamstringing Jot's ability to do any damage to Buffalo Wings. However, Buffalo Wings was unable to fully control Jot due to the robot's bigwheel design. As a result, the match went the full three minutes, with both robots emerging basically unscathed and fully operational. Ultimately, the judge's decision went to Buffalo Wings, with control and aggression both being heavily weighted against Jot, ending the robot's run for the event with a 2-2 record on the day.

	===Overview===		===Overview===
	Jot is a 3lb robot designed and ~~built~~ by [[Max Morningstar]], first competing at the January 2024 New Bots event at NHRL. Morningstar came up with the idea to build Jot while reflecting on the [[2023 Championships]], in which cam lifter [[Supreme Ruler]] and corral bot [[Full Court]] made deep runs into the 3lb and 12lb brackets respectively, with the latter taking home the Golden Brett in its weight class. Morningstar wanted a design that could combat these styles of robots while still being competitive against vertical spinning robots. While in the shower, Morningstar was hit by a flash of inspiration, surmising that a bigwheel bot was the ideal counter to both types of designs, being able to bulldoze over corral bots while also being largely immune to cam lifters, which rely on the low ground clearance typical in meta 4WD vertical spinner designs.

	In coming up with the Jot design, Morningstar looked to [[Starchild]] for initial inspiration. Having seen the Starchild variant [[Axis of Evil]] compete in the August 2023 event, Morningstar knew one of the biggest drawbacks to the design was the challenge of lining up hits with the robot's rear-mounted vertical spinner. To fix this, Morningstar combined the big wheels and elongated chassis of Starchild with a horizontal blade, envisioning a robot with a thwacking attack pattern that would be easier to drive and land reliable hits with. Having seen the dominant performance of the thagomizer-style robot [[Maximizer]], Morningstar believed the design would be versatile enough to counter cam lifters and corral robots while still being competitively viable versus 4WD vertical spinners, which typically have less armor on the sides than the front.

	Heading into the June event, the primary design challenges facing Jot were making the drive more controllable and figuring out a way to keep the weapon parallel to the ground. To increase drivability, the chassis was redesigned so that there was a secondary axle for the wheels to ride on, connected via belts to the Repeat Drive Max motors that ran Jot's drivetrain. This added an additional reduction onto the wheels, bringing their speed into a still quick but far more controllable RPM range. This chassis redesign, along with the transition from aluminum frames to a UHMW tail, meant that Jot would look radically different from its January 2024 iteration.

This chassis redesign, along with the transition from aluminum frames to a UHMW tail, meant that Jot would look radically different from its January 2024 iteration.

	Fixing the weapon of Jot took a little more design effort. The challenge was figuring out how to get power out to Jot's weapon, which was located on the end of its new UHMW tail. Keeping the weapon motor mounted near the chassis, like how Jot appeared in January 2024, would mean running an exposed belt all the way along the tail, a juicy target for any opponent to try and snipe. Mounting the motor closer to the weapon would help reduce the threat of belt loss, but similarly expose the motor wires to damage. Rather than try to devise a protective housing for either the weapon belt or weapon motor wires, Morningstar decided it was safer to direct drive the weapon and to have a dedicated battery and receiver for the weapon motor. The downside to this decision would be that the weapon motor would be directly in the path of attack for any robots with horizontal weapons. Morningstar needed a motor that was strong enough to act as a hubmotor, and durable enough to sustain any direct weapon hits. Conveniently, this seemed like a perfect application for the newly released JCR-4935 motor from [https://justcuzrobotics.com/products/jcr-4935-1000kv Just Cuz Robotics]. With a new drive and weapon setup, Jot was coming into NHRL's June 2024 event with renewed vitality.		Fixing the weapon of Jot took a little more design effort.

	Unfortunately, much like in January 2024 the biggest issue for Jot would ultimately be a lack of testing. Upon arriving to the June 2024 event and testing the new Jot design for the first time, several problems emerged. First, while swapping to belts on the drivetrain did make Jot more controllable, the belts were prone to slipping on the 3D printed TPU wheel hubs. Additionally, the TPU chassis for Jot, which was significantly thinner than January's chassis due to weight constraints, allowed the drive motors and wheel axles to deflect towards each other, further loosening the belts. The belts had so much slip that Jot failed its first attempt at passing safety because it could not show enough controlled movement. The addition of some flange washers and zip ties were able to stabilize the axles and tighten the drive belts enough for Jot to move, but its maneuverability was hindered for the duration of the event.

	=== Robot Combat Event @ RCE ===		=== Robot Combat Event @ RCE ===
	Following a rough 0-2 showing at NHRL's June 2024 event, Morningstar sought to fix some of the most glaring design issues with the bot ahead of the very first Robot Combat Event @ RCE, a new beetleweight event run by veteran NHRL competitors and father-son duo [[Glenn Boxell]] and [[Brian Boxell]]. With this redesign, Morningstar sought to eliminate two of the biggest drivetrain design flaws that had faced Jot in June: the drive belt slippage due to the high traction of Jot's cleats, and general floppiness of the TPU chassis compromising drive belt tension. To solve these issues, Morningstar added aluminum plates to the side of Jot, and swapped from belts to 3D printed gears. Originally hoping to use a metal pinion gear (but unable to find one of the desired mod) the decision was made to print the wheel-side gear out of TPU (to be screwed into the wheel itself), and the motor-side gear out of PLA+ (to be secured with two setscrews onto the drive motor shaft). With limited testing showing positive results for the new drivetrain, Morningstar believed that the RCE@RCE event would be a redemption run for the Jot design.

	Jot's first fight of the event was to be against [[The Fool]]. Morningstar was excited for this fight because the vision for Jot when it was initially designed was for it to be a hard counter to camlifter-style bots like The Fool. Unfortunately, far from a brilliant display of the Jot design, the fight was cut short due to another dissatisfying drivetrain failure on Jot. The PLA+ pinion gears deformed on the drive motor shafts, disabling Jot and ending the fight in less than a minute. Once again, Jot had been crippled by an issue easily detectable if the robot had been more thoroughly tested.		Jot's first fight of the event was to be against [[The Fool]].

	Frustrated by a lack of competitive performance, and by the design challenges posed by Jot's long thwacking tail, Morningstar decided to once again radically redesign the Jot chassis between events. Abandoning the tail (but keeping the JCR-4935 weapon motor, which had proven to be reliable in the NHRL June 2024 event) Jot was refashioned into an undercutter. As part of the redesign, and inspired by damage taken to Jot's bigwheels in grudge matches at RCE@RCE, Morningstar also came up with a new design for Jot's bigwheels, sandwiching Jot's spiky spring steel cleats between two 1/8" UHMW bigwheels instead of mounting the cleats externally to 1/4" UHMW. The hope for this new design was to keep the cleats more protected and therefore more likely to stay on the robot throughout a fight. With new wheels, a new design, and a notable lack of testing, Jot was once again packed up to compete in the final NHRL qualifying event of the year.

	====Jot vs [[Little Melty]]====		====Jot vs [[Little Melty]]====
	Jot's second fight was against another Rose-Hulman bot, Little Melty. Little Melty, as its name suggests, was a meltybrain design where the entire robot spins up to high RPMs, turning its own chassis into a primary weapon. Jot once again had a lucky break when the driver of Little Melty accidentally put the robot into the cage upside down, obscuring the directional LEDs that would have allowed them to see what direction the robot thought it was facing. Without these LEDs, the team was unable to effectively control their robot, piloting it into the walls by their starting corner, where the robot remained until the match ended. This was good news for Jot, as unbeknownst to the Little Melty team the hub holding Jot's wheel onto its drive axle was loose, and the wheel had begun to creep towards the edge of the axle as Jot approached its opponent's position. Had Jot maneuvered more aggressively, or taken a direct hit from Little Melty, Jot likely would have been quickly disabled. Luckily, ~~Jot driver [[Max~~ Morningstar]] noticed the wheel start to shift and wisely kept Jot's movement to a minimum until Little Melty tapped out, granting Jot its second win and a berth in the January 2024 3lb bracket.

	While anticlimactic, this was a critical fight for Jot because it exposed the glaring drive and gyroscopic issues caused by the robot's design. First, Jot's drive was incredibly sensitive. Its wheels were directly driven by Repeat Drive Max motors, which are designed for significantly smaller wheels than those boasted by Jot. Even with settings turned way down on Morningstar's controller, Jot accelerated quickly at even small inputs, making the robot very difficult to drive. This difficulty was exacerbated by the gyroscopic forces caused by Jot's weapon, which made Jot want to simultaneously not drive straight and attempt to roll over when turned. The combination of these factors would greatly inhibit Jot's ability to effectively damage opponents throughout the January 2024 event.

Conveniently, this seemed like a perfect application for the newly released JCR-4935 motor from [https://justcuzrobotics.com/products/jcr-4935-1000kv Just Cuz Robotics]. With a new drive and weapon setup, Jot was coming into NHRL's June 2024 event with renewed vitality.

	Unfortunately, much like in January 2024 the biggest issue for Jot would ultimately be a lack of testing. Upon arriving to the June 2024 event and testing the new Jot design for the first time, several problems emerged. First, while swapping to belts on the drivetrain did make Jot more controllable, the belts were prone to slipping on the 3D printed TPU wheel hubs. Additionally, the TPU chassis for Jot, which was significantly thinner than January's chassis due to weight constraints, allowed the drive motors and wheel axles to deflect towards each other, further loosening the belts. The belts had so much slip that Jot failed its first attempt at passing safety because it could not show enough controlled movement. The addition of some flange washers and zip ties were able to stabilize the axles and tighten the drive belts enough for Jot to move, but its maneuverability was hindered for the duration of the event.

	After Jot's loss to Not Sure, it became clear that the most critical design flaw for Jot was how its wheels were secured to their hubs and constrained on their axles. In an attempt to rectify this issue on the fly, ~~driver [[Max~~ Morningstar]] reapplied threadlocker to the screws securing the cones to Jot's axles, and added additional washers to try and space out the wheels from their respective cones to avoid the same failure that occurred in Jot's previous fight. Even in a favorable matchup, the odds of a Jot victory given all these design issues would have been long. However, the next matchup was highly unfavorable: Singularity.

	Designed by the team behind the ring spinner [[Event Horizon]], Singularity was a dual-ring spinning bristlebot, that used the vibrations caused by its own spinning weapons to shuffle the robot around the arena. Bristlebots are typically sluggish, but Singularity was solidly mobile, and was hungry to stay in the competition as it too was coming off of a first round loss. While Jot had never officially fought Event Horizon, in the January 2024 NHRL event the two robots had participated in a rumble together. In the rumble, Event Horizon was able to rip one of Jot's wheels clean off, and was gifted that wheel as a trophy. In keeping with this history, Morningstar told the Singularity team that if they were able to cut through one of the UHMW spokes of Jot's wheels, he would give them a second wheel.

	The fight itself was brutal, and short. There was a brief exchange in which both robots emerged slightly battered, followed by a devastating hit that caused not just one but both of Jot's wheels to fall off their hubs, instantly disabling the robot's drive. Morningstar quickly tapped out, and rewarded the victorious Singularity team one of Jot's wheels, which indeed sported a spoke cut clean through by Singularity's counter-rotating weapon rings.

			=== Robot Combat Event @ RCE ===
			Following a rough 0-2 showing at NHRL's June 2024 event, Morningstar sought to fix some of the most glaring design issues with the bot ahead of the very first Robot Combat Event @ RCE, a new beetleweight event run by veteran NHRL competitors and father-son duo [[Glenn Boxell]] and [[Brian Boxell]]. With this redesign, Morningstar sought to eliminate two of the biggest drivetrain design flaws that had faced Jot in June: the drive belt slippage due to the high traction of Jot's cleats, and general floppiness of the TPU chassis compromising drive belt tension. To solve these issues, Morningstar added aluminum plates to the side of Jot, and swapped from belts to 3D printed gears. Originally hoping to use a metal pinion gear (but unable to find one of the desired mod) the decision was made to print the wheel-side gear out of TPU (to be screwed into the wheel itself), and the motor-side gear out of PLA+ (to be secured with two setscrews onto the drive motor shaft). With limited testing showing positive results for the new drivetrain, Morningstar believed that the RCE@RCE event would be a redemption run for the Jot design.
			====Jot vs [[The Fool]]====
			Jot's first fight of the event was to be against [[The Fool]]. Morningstar was excited for this fight because the vision for Jot when it was initially designed was for it to be a hard counter to camlifter-style bots like The Fool. Unfortunately, far from a brilliant display of the Jot design, the fight was cut short due to another dissatisfying drivetrain failure on Jot. The PLA+ pinion gears deformed on the drive motor shafts, disabling Jot and ending the fight in less than a minute. Once again, Jot had been crippled by an issue easily detectable if the robot had been more thoroughly tested.
			====Jot vs [[Uhhh]]====
			A strategic use of superglue helped get Jot into fighting shape for its final fight by hard-fastening the PLA+ gears to the drive motor shafts, but despite this improvised fix Jot's final fight of the day was even less impressive than its first. Facing [[Uhhh]], a 4WD vertical spinner, Jot was able to make its way over to its starting square but as the match began found itself unable to move, and was quickly counted out for a loss. A post-fight look at Jot's internals revealed that the issue was Jot's FingerTech power switch, the screw of which had stripped out. It would seem that the switch had been just tight enough to give Jot power enough to make it to the starting square, but then soon after came slightly loose and cut off power to the drive system of the robot, ending Jot's day and leaving the robot with another disappointing 0-2 record for the second event in a row.

			=== NHRL October 2024 ===
			Frustrated by a lack of competitive performance, and by the design challenges posed by Jot's long thwacking tail, Morningstar decided to once again radically redesign the Jot chassis between events. Abandoning the tail (but keeping the JCR-4935 weapon motor, which had proven to be reliable in the NHRL June 2024 event) Jot was refashioned into an undercutter. As part of the redesign, and inspired by damage taken to Jot's bigwheels in grudge matches at RCE@RCE, Morningstar also came up with a new design for Jot's bigwheels, sandwiching Jot's spiky spring steel cleats between two 1/8" UHMW bigwheels instead of mounting the cleats externally to 1/4" UHMW. The hope for this new design was to keep the cleats more protected and therefore more likely to stay on the robot throughout a fight. With new wheels, a new design, and a notable lack of testing, Jot was once again packed up to compete in the final NHRL qualifying event of the year.
