FAQ

I have purchased an Ultimate 2.0, but I have issues with its use.

Q1. Why doesn’t the robot work after powered on? The main board suddenly restarts when I try to drive motors.
a. The robot might be running out of battery. Please charge the batteries or use new batteries. (Note: Please use batteries with low internal resistance which can supply enough power for the robot.)
b. Make sure you’ve downloaded related program or firmware for the robot. Otherwise, it won’t be running.
c. Please check if the motors on the robot are wired correctly.
Q2. When I try to turn the robot to the left, it turns to the right. Why and how to fix this problem?
You may need to switch the order of two wires (Port 1, Port 2) to correct the rotation direction.
Q3. Why there is noise after I got the robot tank running?
a. Please check if the driven wheels are correctly installed.
b. Please adjust the bearings of the driven wheel to make sure they are not too tight or too loose.
c. Please make sure encoder disk and the interface of the photoelectric switch are separated from each other.
Q4. Why can’t I connect the app with the robot via Bluetooth?
a. Please visit learn.makeblock.com/c to check if your smartphone is compatible with the app.
b. Please try restarting the app or reset the main control board on the robot.
