I have assembled and programmed the robot a few weeks ago and it worked absolutely fine. It has been used a few times since but has now developed a "glitch in the back left lower servo.
It acts completely randomly and constantly jitters. I have checked connections and swapped out the servo with the replacement that is in the kit with no change in results.
Does anyone have any suggestions as to what I might do to resolve this?
Thank you
Do you have a video?
