Part V Ultimate 2.0
What should I do if my Ultimate 2.0 motors are not working
properly
Situation 1
Motor(s) is not turning at all.
Please check:
a. Make sure the motors are installed and connected correctly.
b. Cable from motor to the main board is connected properly and make sure the cables are
working.
c. Check if there is anything get stuck in the wheels, like cables. You can turn the wheels in
clockwise or anti-clockwise order to test.
d. Try some new batteries.
e. It may not move if the speed is too slow like 20 or 30. So try speed at 200.
This is Ultimate 2.0 instruction
Situation 2
Ultimate 2.0 cannot move straightly (two motors have different speed)
Due to the motors’ installation difference, it is normal that two motors don’t have exactly same
speed. If they differ a lot, please check:
a. If there is anything get in the left or right wheel, like cables.
b. Speed is set too slow that one side moves a little while the other side doesn’t move. So try a
larger speed like 100.
c. Motors cannot get enough power energy. Try to change the battery or charge the battery.
If the speed of both sides still differs a lot, you may try to adjust the speed to with different power,
like setting left speed as 100, while right 110. Several tests are necessary to get expected result.
Situation 3
Why it moves backward when I ask it to move forward? It unclamps when I tap
clamp?
It is wiring issue. Check the wiring refer to below chart.
