Will you still use the gyroscope with v5? Is it more accurate to turn with the v5 built in encoders?
Yes, you can still use that gyroscope. Which works better will depend the circumstances. Is the robot bouncing, going over obstacles, or similar such that the built-in encoders will measure more rotation than the wheels have actually rolled across the floor? Is there a lot of vibration or similar that is messing with the gyroscope?
