Operation Guide

The chassis can be controlled and operated using either a Joystick Controller or a Computing Unit.

Please ensure all switches (SWA/SWB/SWC/SWD) are in the top position before you do any actions. This will place the machine in a stop state, preventing the chassis from operating.

Item Chassis Control Mode Dual Ackermann Mode Spinning Mode Translation Mode
Joystick Controller
Switches Switch SWB to middle Switch SWC to top Switch SWC to middle Switch SWC to bottom
Left Joystick \ Move up/down to control forward/backward movement Move up/down to control counter-clockwise/clockwise rotation Move up/down to control forward/backward movement
Right Joystick \ Move left/right to control steering angle \ Move left/right to control left/right turning
Computing Unit
Switches Switch SWB to bottom and switch SWC to middle Follow the steps in the Development and Operation Tutorials to start the action.

PC Connection

To achieve efficient data communication and control within the system, we provided a USB-to-CAN Adapter for users to connect the chassis to PC.
