2 wheel self-balancing robot


I would like to built a 2 wheel self-balancing robot which will be getting information about his angle from sensor (accelerometer). I want to ask you, if it will be good to use just T'REX robot/motor controller or I have to buy something like this  with extra motor controller.
Thank you very much for your answer! :)

The T'Rex does not have the necessary onboard sensors for self-balancing. The link you provided also shows which IMU they used. The L298 motor controller is not necessary if you have a T'Rex. Note that if you have a separate microcontroller, you only really need the L298.

Hi, thanks for answering! Hm I dont really understand, you wrote that I dont need L298 because I have T'Rex and then you wrote that I need it. I think you thought, I need GY-80 BMP085 9-Axis Magnetic Acceleration Gyroscope Module, Or? :)


I Have separate microcontroller - arduino nano, uno, mega and raspberry pi. I can use any of them.

I just need to know if I need another motor controller despite of having T'Rex and one acceleration gyroscope module?

Thanks! :)

The T'Rex controller has it's own microcontroller onboard. What Cbenson meant is that you would only need the L298 if you have a seperate microcontroller which is the case. So you would only need the L298 and the acceleration and gyroscope module.

But if you have a T'Rex controller already, you would only need the acceleration and gyroscope module.

Hope that clears your confusion.
