__1 May 2020 Update:__ the front ball caster seemed to get hung up sometimes when trying to transition from floor to carpet. David Anderson had cautioned against using a front caster in [his YouTube video|https://youtu.be/8CXReb7f0Eo], so this was hardly an unknown. Due to this issue the front caster has been removed, and the symmetry of the robot sacrificed a bit by moving the wheels forward about 1cm in order to set the balance aft. Even with this change of balance it's still possible for the robot to fall forward onto its nose. Some kind of curved skid to keep this from happening could be fitted, but currently the plan is to change this from a 2 wheeled to 4 Mecanum wheel robot, so no further changes to this design are expected.
