A New Approach to Robot Motor Control

Abstract

This poster details the motor control improvements to Fermilab's Remote Viewing Robot (RVR). It is a robot tasked with remotely investigating issues within the accelerator tunnels at Fermilab. Initially controlled by a single Raspberry Pi that housed all the robot s operations, the RVR will now use a Raspberry Pi Pico W for its motor control. This was achieved using Pulse Width Modulation (PWM) to allow for precise speed and torque control for the robot. This enhances the robot s reliability. By addressing the challenge of navigating high radiation environments, the upgrade helps assist the RVR s goal of decreasing the need for human intervention in accelerator tunnels.
