LiDAR Gimbal with PID Control (VANDERBILT ROBOTICS, 2023)

Problem:

  • In order to save weight, the team elected to design the rover’s vision system to operate without the need for suspension

  • This approach introduced a need for a gimbal system in order to normalize the frame of reference of our LiDAR data

Challenges:

  • Designing a 2-axis gimbal (pitch, roll) without any cantilevered axes

  • Producing a PID controller that consistently performed within our desired margin of error

Results:

  • Designed, prototyped, and programmed a unique gimbal design that fulfilled the subsystem requirements

  • Packaged electronics and control sensors into a single standalone unit allowing for parallel develop and easy removal from full rover assembly
