Our biggest problem is that, for some reason, the motor drivers and the Arduinos are receiving excess voltage. We do not know how this is happening. However, this has caused us to burn through (not literally) several motor drivers and at least two Arduinos. We are managing this issue by constantly checking the Arduinos and motor controllers. We have backups and meticulously test the wires to ensure they are safe.
Another issue is that our robot tends to drive off the ramp on its left side. This is caused by the board bending and the robot being too wide. We plan to drill out the wheels to create a narrower wheelbase.
We did not make any significant changes to the robot itself, but we did modify our ramp. We shaved down the edge to allow for smoother robot climbing. We also changed our specifications because we had difficulty reaching a 45-degree incline.
There are no schedule changes.
