Project LiftOff
Project Liftoff is a 3lbs MeltyBrain (a robot that moves using translations drift as its entire body spins at 1000 to 3000 RPM.

For 2021, Project Liftoff is beginning its third major revision.
- 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
- switched from 8" Aluminum rings to 9" AR-500 ring with tooth (and hand cut HDPE)
- 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)
- Rev-3 : 2021 Same electronics as Rev-2; improved algorithm, wheel orientation, and return to accelerometer.
- 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
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.
