Stopping Servos

An issue we’ve commonly faced while operating our robot is that the servos will keep spinning if the script crashes or if we exit the script via CTRL+C. I’ve always had the script for this exact purpose but it has to be executed manually after exiting the main script, i.e. python3 This script...

First, I’ll explain what a PID controller is and how we will use it on our robot. PID stands for Proportional-Integral-Derivative controller. It’s...

Our two USB2AX dynamixel servo interfaces arrived in the mail today. We purchased these as they’re a far smaller alternative to the USB2Dynamixel (see image below) or the OpenCM board. We also don’t have to mess around with another layer of code (as we would on the OpenCM) – communication is direct. After reading the...

Of Wheels, Plastic, and Not Much Else

We didn’t spend long on the robot today, just a few minutes to get the main body finished. Matthew and I have removed the excess plastic from the two front wheels. Matthew attached them to the robot after holes were punched by Riley using a screwdriver.
