Colossal Avian

From iRobotics Tech Wiki

Overview

Colossal Avian is Parts & Wreck's Senior Year 30lb Robot.


Chassis

Colossal Avian uses an iRobotics classic waterjet cut tab and slot 2024 Aluminum chassis. The exterior panels are all 1/2" thick, with 1/8" thick top and bottom plates and 3/8" thick for the interior upright panels.

Drive

Colossal Avian features a indirect drive drivetrain where the motor is belted to two wheels on each side, helping to isolate the motor from impacts. The wheels both ride on cantilevered shoulder bolts, which act as the drive axles. The cantilever design allows the drive axles to be completely isolated from the outer armor, meaning that the wheelguards can be completely ripped apart without impairing the drive functionality. The trade off is that the shafts themselves are less durable as they are not supported on two sides.

Components:

  • Motor: Flashhobby 3536 EVO 1450kv
