Inverted Pendulum/closed loop stepper motor

Job ID: 31847369

Budget: $250 – $750 CAD

I have a hobby project that I am working with and now could use some help. Having successfully small scaled the project I wish to supersize it. Essentially I am working with an inverted pendulum (self balancing robot). I am stuck at the point of integrating a large stepper motor (closed loop) into the system.
Effectively I have an Arduino Nano, MPU 6050, Single axis (roll), Kalman filtering, Operating max/min limits <> roll angle, PID, Serial Plotter, Closed loop Stepper motor/driver/encoder.
I cannot make all work together seamlessly in an orderly way. Can you help?
