How to Jog the Meca500 Robot Using the MJ3 Joystick

The MJ3 is a precise 3 axis USB joystick that can be used to jog the robot. It acts as a plug and play device with the Meca500's web interface. The joystick controls can be mapped to both joint and cartesian displacements. With a simple click of a button on the joystick, the jogging mode can be changed from joints to Cartesian (with respect to WRF or to TRF).

For Safety reasons:
  1. The Ctrl key enables interlock. Pressing and holding the Ctrl Key is mandatory to activate the joystick controls.
  2. In order to use the joystick, the joystick tab must always be in focused state in the web interface. The joystick inputs will be ignored by the web interface immediately after the Jogging panel is switched to either Joint or Cartesian tabs

  1. Plug the joystick into any USB2.0 or higher USB port.
  2. Log into the Meca500's web interface in your Chrome browser using the robot's IP address (Default:
