Getting Started with VEX Robotics Using MATLAB and Simulink, Part 6: Proportional Motor Control During Obstacle Detection

From the series: Getting Started with VEX Robotics Using MATLAB and Simulink

Gary Garber, BU Academy, Boston, MA

Learn to use a simple proportional (P) controller in Simulink^® to precisely control the motion of a robot during an obstacle detection course. The intended behavior of the robot is to slow down, and eventually stop, as it gets closer to the obstacle in front of it that is sensed by the ultrasonic sensor. This is a good use case for robots that need to be positioned in precise locations during an autonomous challenge and thus avoid slipping or skidding due to abrupt stops of the motor.
