Paul, please give more information . . . Paul, we can help you here but we do need a bit more information to go on. Firstly, which PicAxe chip are you using, and are you using one of the pre-built PicAxe boards or is this on a board of your own design? Also, how is the robot …

Hi Paul. You’ve made a Hi Paul. You’ve made a symbol Servo_turn but you haven’t used it anywhere. The servo needs time to reach it’s position after you tell it to turn. The reason being the picaxe executes commands much faster than the servo can move. So you slow the processor d…
