=== '''Description''' ===
Plyohazard is a Featherweight (30lb) robot initially built as a joke robot.

The first revision was entirely pine wood, with a welded mild steel wedge. Revision 2 was intended to be the minimum viable product to qualify for the December Finals. The bot was entirely made from 0.1" and 0.187" AR500 panels cut by SendCutSend and welded or nutstrip'd together. The bot used single stage belt reduction for both the drive and weapon, and had two vertical weapons that were swappable between a hammer spinner and a framing saw. The front wedge was 0.25" AR500. The bot kept the wood theme, and used faux wood decals to fake it's construction method. This bot was fun, but not very competitive. Repairs on this bot kept it running until September 2022, where it competed as a flamethrower and again qualified for the December finals.[[File:PXL 20210515 142919586.jpg|alt=|thumb|Plyohazard V2]][[File:Plyohazard (1).jpg|thumb|Plyohazard V1]]
Revision 3 was a 4-bar lifter, which debuted at the December finals. It went 2-2 in it's first event, with a notable win over Phenomenon.{{Bot Stats|bot=Plyohazard|class=30lb}}

Spine Crawler is a walker Bot that uses a modified Jansen linkage for its legs. The legs are one TPU part, with flex points in critical locations to produce the desired motion profile.

The hammer uses a Grashof linkage, which is a 4 bar linkage that allows continuous rotation. Additionally, the mechanism is designed with a quick return ratio, meaning that the hammer swings faster in the downstroke and has more torque on the return to assist in self righting.{{Bot Stats|bot=Spine_Crawler|class=3lb}}

The bot was entirely made from 0.1" and 0.187" AR500 panels cut by SendCutSend and welded or nutstrip'd together. The bot used single stage belt reduction for both the drive and weapon, and had two vertical weapons that were swappable between a hammer spinner and a framing saw. The front wedge was 0.25" AR500. The bot kept the wood theme, and used faux wood decals to fake it's construction method. This bot was fun, but not very competitive.

Remzak: Rev 6, new media

[[File:LiftoffTPU.jpg|thumb|Project Liftoff - February 2022 (rev 6.0) Pictured before Motorama Robot Conflict]]
[[File:Project Liftoff - September 2021 (rev 5.0).jpg|thumb|Project Liftoff - September 2021 (rev 5.0), pictured before the September 2021 event. The bot went on to go undefeated, winning the 3lb division with 4 KOs and 3 judges decisions.]]
Project Liftoff is a 3lb MeltyBrain (a robot that moves using translational drift) as its entire body spins at 2000 to 4000 RPM.

As of April 2022, Project Liftoff is in it's sixth major design generation.
[[File:Project Liftoff a March-2019.jpg|alt=|thumb|Project Liftoff - March 2019 (rev 1.0)]]
* Rev-1.0 : March 2019
** Processor: Arduino Nano
** Accelerometer: common MPU 6050 (+/- 16g 12 bits)
** Receiver Interface: standard RC-PWM into UART
** Motor Control: OneShot125 via PWM manipulation @ ~800Hz
** External Sensors: none
* Rev-1.1 May 2019
** switched from 8" Aluminum rings to 9" AR-500 ring with tooth (and hand cut HDPE)
*** this AR-500 tooth proved to be too pointed and became embedded in arena wall several times
[[File:Project LiftOff b May-2019.jpg|alt=|thumb|Project Liftoff - May 2019 (rev 1.1)]]
[[File:Project LiftOff c Aug-2019.jpg|alt=|thumb|Project Liftoff - August 2019 (rev 1.2)]]
[[File:Project LiftOff d2 Sir Pops Alot Aug-2019.jpg|alt=|thumb|Sir Pops A Lot (derivative) - August 2019 (rev 1.15)]]
* Rev-2.0 : 2020
** Processor: Teensy 4.0
** Accelerometer: none… used motor eRPM telemetry from ESCs via bidirectional dShot
** Receiver Interface: RC-SBUS into UART
** Motor Control: dShot600 via SPI manipulation @ 8000Hz
** External Sensors: active IR
** CNC'd HDPE body
** New 8" AR-500 ring and tooth (with a more blunt tip)
[[File:Project Liftoff July-2020.jpg|alt=|thumb|Project Liftoff - July 2020 (rev 2.0)]]
[[File:Project LiftOff f Flip n Cut July-2020.jpg|alt=|thumb|Flip N' Cut (derivative) - July 2020 (rev 2.05)]]
[[File:Project LiftOff g Sept-2020.jpg|alt=|thumb|Project Liftoff - September 2020 (rev 2.1)]]
* Rev-3 : 2021 Same electronics as Rev-2; improved algorithm, wheel orientation, and return to accelerometer (see March-2021 picture below).[[File:PXL 20210320 135444503.jpg|thumb|Project Liftoff - March 2021 (rev 3.0)]]
** Processor: Teensy 4.0
** Accelerometer: H3LIS331DL (+/- 400g 16 bits)
** Receiver Interface: RC-SBUS into UART
** Motor Control: dShot600 via SPI manipulation @ 8000Hz
** External Sensors: active IR
** changed to 4S (from 3S)
** Other Details:
*** Switched to a "Motor Pod" that is sandwhich'd by two clam shell HDPE halves.
*** Put wheels in-line with weapon tooth (what was Jim thinking).
*** misc. software improvements (algorithm simplified)
* Rev-4 : 2021 (May-2021 and July-2021) Same as Rev-3 except:
** Quest for a more durable motor...
*** May-2021: created a custom motor with internal thrust bearing with "no-name" motors (internal thrust bearing still failed by the third fight).
*** July-2021: Put a thrust bearing inside a PropDrive motor
**** Combing a PD-2826 stator with a PD-2830 motor-can gave the needed room. Could do the same thing with a PD-2830 stator and a PD-2836 motor-can (the PD-2836 is really a 2834, 4mm larger than the PD-2830).
**** This motor sacrificed power for durability. It was durable... however, it changed the failure point to the set screws and motor axle.
** Wheel Axis returning to 90 degrees from weapon
*** when wheels are inline with the weapon, the hockey-pucking is far worse.
** Making weight distribution fully symmetric...
*** a large counter-balance weight opposite (single tooth) weapon increases hockey-pucking... an impact causes the tooth to stop, but the other side of the Bot goes flying due to its own momentum.
*** change to fully symmetric two weapon teeth, allowing us to avoid a large counter balance weight.
** changed to full round HDPE body
*** prior HDPE cut-outs were to save weight
*** prior circular AR-500 weapon ring kept wall collisions "safer" and minimized pinning risk, and allowed us to hollow-out the HDPE.
*** re-design and re-cut of HDPE shell.
** weapon ring changes
*** make weapon ring narrower to decrease weight to offset increase in HDPE
*** remove bolt holes from weapon ring (to maximize its strength)
** [[File:MotoramaTPU.jpg|thumb|Project Liftoff - Side profile (rev 6.0)]]July-2021: first usage of titanium wheels. Thank you to Joe Fabbiani (Smeeeeh) and Calvin Iba (Lynx) for sharing the idea and showing the way - see Lynx May-2021 competition.
* Rev-5 : Sept-2021 Same as Rev-4 except:
** Major Motor redesign
*** Switched from PropDrive 2830 to PropDrive 2836.
**** more power.
*** Changed to a Hub Motor wheel attachment
**** 6mm dead axle
**** two 626 bearings (1000+ pounds of dynamic load)
**** custom machined aluminum inner (motor-can) and out (wheel) hubs
***** done on home CNC machine (0.2mm layer height)
**** titanium wheels (via send-cut-send)
**** no more set screw failures!
**** Thank you to Brian Boxell (Eruption) for giving us some direction, encouragement, and help on Hub Motors.
** Yet another AR-500 weapon ring re-design
*** Needed to find 80+ grams to offset the increased weight from the above Hub Motors.
*** Same 0.25" AR-500, but...
**** via send-cut-send.
**** Previous 326g (almost a full round circle) to 241g (almost rectangular)
**** Still no holes, very tapered/narrow in the middle.
** Both the above required a re-design of HDPE shell.
**
* [[File:Annotated Project LiftOff Internals.jpg|thumb|Annotated Image of Sept-2021 Project LiftOff internals. The accelerometer and RC receiver are on the underside of the PCB.]]Rev-5 Issues that we had hoped to address for Nov-2021 :
** In the "first attempt" of CNC'ing aluminum I made several mistakes that led to slight defects in the motor hubs (leading to non-alingment in the Hub Motors that were used... rubbing/friction/added heat/lost power).
*** Over-clamping & un-even clamping.
*** Slight alignment issues with double sided parts.
** We never (software) tuned Project LiftOff... we were making hardware fixes until midnight on Friday.
*** The controls were upside down and backwards all day on Saturday.
*** The IR object/wall detection was never used since it was so misaligned.
** Possibly make some ESC changes to improve drift performance.
** Continue to ponder how to avoid "hockey pucking".
** "Save the Arena Floor" upgrade...
*** We will modify the software to take advantage of the wheel telemetry information we have (via bidirectional dShot) to avoid "spinning our wheels".
*** This will not only stop us from ripping apart the arena floor (like a saw blade), but:
**** It will be much quieter.
**** It should enable us to spin up much faster (using static friction instead of dynamic friction).
* Rev-6 : February-2022 Same as Rev-5 except:
** Major Shell Redesign
*** After failures during the December finals, we have decided to move away from UHMW or HDPE as shell materials. These materials were too prone to failure around the metal ring.
*** The outer shells are now printed out of TPU plastic.
*** Smaller batteries
** New AR500 weapon options
*** Long reach weapon, made of stacked 1/8" AR500.
**** via send-cut-send.
**** Allows us to play the reach game with other horizontals, and keeps big wheel bots away from our chassis.
**** Welded together, questionable structural integrity.
** New PCB iteration
*** Smaller
*** Lighter
*** Bluetooth
**** Not yet implemented, but functional on the bench
**** Provides battery, temp, and speed telemetry in real time
*** Smarter layout, better components.

===Robot Facts===
The first appearance was at the March 2019 NHRL event. The very first version used an 8" diameter aluminum pipe cut into two 1/2" thick slices with a notch cut out for the AR500 tooth (with two bolt holes).

Since then, Liftoff has used several laser or waterjet-cut AR500 steel rings. These rings have been sandwiched or otherwise mounted to CNC'd UHMW or HDPE bodies that contain the primary electronics and battery. This has proven to be a durable, and adaptable construction method.

Plyohazard is a Featherweight (30lb) robot initially built as a joke bot.

The first revision was entirely pine wood, with a welded mild steel wedge. It had a diminutive vertical disk spinner, mounted on maple uprights. The bot used old parts, and polybelts, with a total investment of ~$200. The drive performance was very poor.

Revision 2 was intended to be the minimum viable product to qualify for the December Finals. The bot was entirely made from 0.1" and 0.187" AR500 panels cut by SendCutSend and welded or nutstrip'd together. The bot used single stage belt reduction for both the drive and weapon, and had two vertical weapons that were swappable between a hammer spinner and a framing saw. The front wedge was 0.25" AR500. The bot kept the wood theme, and used faux wood decals to fake it's construction method. This bot was fun, but not very competitive.

===Robot Facts===
The first appearance was at the March 2019 NHRL event. The very first version used an 8" diameter aluminum pipe cut into two 1/2" thick slices with a notch cut out for the AR500 tooth (with two bolt holes).

Since then, Liftoff has used several laser or waterjet-cut AR500 steel rings. These rings have been sandwiched or otherwise mounted to CNC'd UHMW or HDPE bodies that contain the primary electronics and battery. This has proven to be a durable, and adaptable construction method.

Traveling to Norwalk

Remzak: /* Flying to Norwalk */

[[File:Norwalk from Google Earth.png|Norwalk, CT as Rendered by Google Earth. Click to see relevant locations.|alt=|thumb]]Norwalk is actually more accessible than you may think! There is also more to do in Norwalk than just fighting robots.

Wikitravel is a great place to get started. Their page on [https://wikitravel.org/en/Norwalk_(Connecticut) Norwalk] has lots of activities.

==== Help for Bot Builders ====
We are always looking for ways to make it easier to compete.

* Folks wishing to come Friday before the event are welcome to use our facilities all day, the team often stays late the night before while preparing for the event.
* 50 Day is staffed M-F 10a-6p. If you want to mail your robot ahead of coming to the event that can be accommodated. We can be there to sign for it.

==== '''<big>Flying to Norwalk</big>''' ====
Flights to Norwalk are plentiful, but require significant transportation after landing. The closest major airports, in order, are LaGuardia, JFK, then Newark.

All of these airports are 50-90 minutes by car, or 2-3 hours via public transportation. If you are flying to the event, renting a car is strongly encouraged. All public transit routes require a significant number of stops and transfers, and will be an adventure in and of themselves. Negotiating this with robots and equipment is unlikely to be an enjoyable experience. Flying into Hartford is only recommended with car rental, public transit options are all over 4 hours.

Generally, the best airport to fly into will depend on what airline you choose to fly with.

=== Staying Overnight in Norwalk ===

==== Recommended Hotels ====

* Sono Marriott
** It can get pricey but it is the closest hotel to arena
* Even Hotel Norwalk
** Affordable, clean, last remodeled in 2018 and about 10 minutes away
* Hotel Zero Degrees Norwalk
** New in 2018 and about 10 minutes away
* DoubleTree Connecticut Avenue
** Decent Hotel

==== Not Recommended - Don't stay here ====

* Red Carpet Inn
* Norwalk Inn

==== Traveling to the Venue ====

* Ride sharing services
** Uber, Lyft, etc
* Car rental may be prefferable
