A project for ROB 550: Robotics Systems Lab course taught in University of Michigan, Ann Arbor. An overview of this project:
- Dynamic control of DC motors to balance and control a wheeled inverted pendulum
- Trajectory Following for a mobile robot
- Use of wheel encoders for performing odometry
- Use of MEMS IMU sensors to determine orientation (heading, pitch angle)
- Build a system from the ground up based on an embedded system
- Use of Beaglebone with Robot Control Library in C for soft real-time control
The control architecture can be explained by the following figure:
Source code for The Robot Control Library is in the folder ~/Install/librobotcontrol. Check out the website, or the github repository for how to use the functionality it provides.
- run
test_motors.cto test the motor standalone balancebot/balancebot.cis the main code which starts two threads, and attaches thebalancebot_controller()function to the IMU interrupt.
