How can I making turning more accurate?
BlockTalk Summary
A LEGO Mindstorms EV3 builder is experiencing accuracy issues with their two-wheel-drive robot's turning mechanism. While their gyro straight-driving code functions effectively, the robot struggles with precision during rotational movements. After approximately five turns, a noticeable two-degree error appears, which continuously compounds and eventually causes the robot to miss its intended destination entirely.
The builder utilizes a gyro sensor to control the robot's navigation, but the current gyro turn code fails to maintain long-term calibration. This cumulative drift means that multi-step routines quickly fall off track, highlighting the challenges of sensor precision in autonomous robotics builds.
To help keep your robot and other precision builds in top shape, you might want to pick up a LEGO storage organizer to keep your sensors and cables neatly sorted. While this specific community query focuses on troubleshooting EV3 programming rather than new product releases, refining sensor code remains a vital skill for LEGO robotics enthusiasts aiming for competitive or exhibition-level accuracy.
I have built a simple LEGO EV3 robot that is 2-wheel drive. I am using the gyro sensor to make movements more accurate. My gyro straight code is working great, but I am having some problems with turning. After many turns (after about 5, there is a noticeable 2-degree difference, which then keeps increasing), it gets off track and ends up far from the endpoint. Here is my current gyro turn code. Do you have any suggestions on how I can make it more accurate? submitted by ...
