Balancing a bouncing ball

Balancing a bouncing ball

Electron Dust shows off a nifty machine that can bounce a ping pong ball, while keeping it balanced and centered on its moving platform. It uses combination of open-source image processing software and Arduino-controlled stepper motors to work its magic.

It is an arduino project with 120 FPS OpenCV image processing and smooth stepper motor moves. The machine calculates the ball’s 3D position from the image processing data and uses this information to control the orange ping pong ball.

Uses an e-con Systems superb See3CAM_CU135 camera. Find out more about the camera here:…

This machine requires the following things to work:

  • 1x Teensy 4.0 Microcontroller
  • 4x StepperOnline DM442S stepper motor drivers
  • 4x Nema 17 Stepper Motors with 5:1 planetary gearbox
  • 1x 48V 8A power supply
  • 1x e-con Systems See3CAM_CU135 camera
  • 1x Windows Computer with OpenCV installed on it –

All the parts defined the Fusion360 project – Custom Windows Application (made with Unity). Read more here:… Complete code and Fusion360 data on Github:…
