6.4. Connecting to the cloud

  • Scan QR Code - your device is now paired with your robot.
  • Insert device to your robot and screw on mounting elements.

6.5. Programming

  • Place your robot with CORE2 facing up and turn it on.
  • Open WebIDE ( and create a new project using template 'self-balancing telepresence' and upload it to your CORE2.

  • When robot is programmed, open its user interface and click 'Turn off motors'.
  • Pinch upper part of your robot and by pushing it back and forward set it to balanced vertical orientation.
  • When you find proper position (when you are using the less force to hold it stable) click on 'Calibrate' button in Web UI.
  • Now after clicking 'turn on motors' your robot will start balancing correctly.

To steer your robot use WSAD keys or arrows. Use G key to switch leg position and 1, 2, 3 keys to change gears.
