Chapter 2: Run! Devastator!
Last revision 2026/01/13
In Chapter 2, we explore the motor setup and steering mechanisms of the Devastator robot, detailing how signals from the micro controller dictate motor speed, direction, and duration for precise movement and control.
In this chapter , we went through the hardware assembling procedure, now it's the time to get it moving! In the following sessions, we will show you how to set up a simple motor driving program step by step.
Moving Mechanism
The mobility of the Devastator is realized by the motions of its motors on each side. The motion of each motor follows the signal sent by the micro controller. To be more specific, 3 parameters are included in a signal, each determines motor’s angular speed, rotation direction and corresponding time duration.
How To Steer The Devastator
The steering angle is determined by the speed difference between its two pedrails. When both pedrails are driven at the same speed, our robot may either go straight forward or backward. However, when speed of these two motors are inconsistent, the larger the difference is, the bigger its steering angle will be. Note: as motors are installed to be oriented in opposite directions, an anticlockwise rotation of the left motor and a clockwise rotation of the right motor drives pedrails in the same direction.
