We wanted to create a video to pass along information to the rest of the VEX community about the VEX EDR Yaw Rate Gyro Sensor, that we learned last year. For the Nothing but Net competition, we came up with the idea for a turreted design that would be able to automatically aim and shoot from any position on the field. The key to being able to make a robot that could do this, was for the robot to know exactly where it was on the field at any time. At the very heart of developing that capability was the need for the robot to very accurately know what direction it was facing at all times by using the VEX EDR Gyro. Through many hours of testing and research, we came to fully understand the gyro operation, calibration, scaling factor, and cause of drift in the measured angle. We ended up winning the Create Award at the 2016 VEX Robotics World Championship, and hope the information we have presented will let other teams successfully use this powerful VEX sensor. We wanted to provide as much information as possible within the time given, so would like anyone wanting to study the code sample in depth, to pause the video as long as they need to.
