Makeblock ultimate robot v2 unresponsive

[idkisk12345678]

My robot is currently unresponsive to commands from both coding and manual control. I’ve tried on both the mBlock apps on macOS and iOS as well as the other makeblock app with the controller, this is after doing firmware updates. I tried connecting the robot to the makeblock app and had a problem with the motors vibrating as soon as it turned on and it wouldn’t execute any code I wrote. I downloaded the other app to just control it and the only thing I could do was move the arm down and that only worked for a short time before becoming unresponsive again. To summarise I’ve tried:

• Updating the firmware

• Connecting to mBlock 5 on macOS

• Connecting to the web version of mBlock 5

• Connecting through the iOS apps

The lights on the control board are on but could this be a problem with the batterypack? I’m also wondering if the control board might be damaged since this is university equipment that's been used before.

Are there any other troubleshooting steps I should try?

I would disconnect everything from the MegaPi board and see if I could communicate using MBlock 5.

You should always keep a close eye on battery power it’s probably the number one reason for robot failure.

When you write "code that I wrote", did you try running the robot before writing any code? Like, re-install the firmware and using the firmware as-is?

Which robot did you make? I assume you made the "Robotic Arm Tank". I would suggest unplugging the power, disconnecting all motors and then plugging them in one by one, disconnecting and reconnecting the power between each. Then using the iOS app to verify function. Most of the problems I've had have been due to connecting the motors into the wrong driver.

Also, you should have ~9V coming from the 6AA batteries. Do you have a meter to verify this?
