Project Liftoff - March 2021 (rev 3.0)

Project Liftoff is a 3lb MeltyBrain (a robot that moves using translational drift) as its entire body spins at 1000 to 3000 RPM.

For 2021, Project Liftoff is beginning its third major revision.

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

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.
