FORAY - Crazyflie Yaw Rate PID Control Modification

Ethan Uetrecht

After setting up the crazyflie as a blimp and performing various tests, one primary issue was noticed when attempting to control the blimp. This issue was in the yaw control; I noticed that for large yaw inputs, the blimp would not turn left or right. Instead, the left and right motors would alterna...

Blimp Orientation Control with IMU

Ethan Uetrecht

I have spent the past weeks assembling a blimp on which to test a feedback control system to aid in controlling the blimp as well as building said control system. The picture below shows the experimental setup. So far, the blimp is assembled and controlled based on IMU motion. The video below...

Motor Feedback Control using IMU

Ethan Uetrecht

This past week I have developed a framework for motor feedback control using IMU (orientation) data. I first wrote scalable motor control software for interfacing with the tb6612. A quick test operation can be seen below. Motor Test: Your browser does not support the video tag. I then integr...
