Remote Controlled Rover
Designing and building a RC Rover with unique competition requirements
The Problem
"Develop a rover in full throttle failure mode to compete for RoverX's contract". This means the motor is always on, and can not be throttled/slowed despite needing the rover itself to stop.
Braking Mechanism
With the condition of the motor always being on, a I developed a ratchet-pawl braking mechanism that would use servo with attached ratchet arm to lower into the pawl which was firmly attached the motor. By adjusting the pawl tooth depth we could have different degrees of braking speed. Testing allowed us to determine an optimal pawl teeth length. I prototyped by using SolidWorks to quickly 3d print pieces and iterate the design on our Rover.
