Connecting a Joystick

Exercising the motors can easily be done using a Joystick in addition to the on-screen slid- ers. Simply connect a joystick to the PC and enable it by clicking in the Joystick check box in the PC utility.

If the box is grayed out, the joystick is not properly installed in your PC and you can click on the “Config Joystick” button to open a configuration screen and the joystick control panel.

Joystick movement should automatically translate into Channel 1 and Channel 2 command values and make the sliders move. These commands are also sent to the controller.

It is strongly recommended that you use an USB rather than Analog joystick.

A joystick test program name “Joytest” is automatically installed in your Start menu when installing the Roborun utility. This program may be used to further verify that the joystick is properly installed in the PC and is fully operational.
