Hardware Preparation
The following is the most streamlined hardware configuration: Rosmaster X3 has this configuration
HT-10A remote control
SBUS receiver
ROS control board
520 motor *4
HT-10A remote control
It is necessary to install 4 No. 5 batteries in advance for the HT-10A remote control to power it:
| HT-10A remote control | Default channel: The remote control does not perform channel mapping |
|---|---|
| CH1 | Right joystick: slide left and right |
| CH2 | Right joystick: slide up and down |
| CH3 | Left joystick: slide up and down |
| CH4 | Left joystick: slide left and right |
| CH5 | SWA channel |
| CH6 | SWB channel |
| CH7 | SWC channel |
| CH8 | SWD channel |
| CH9 | VRA channel |
| CH10 | VRB channel |
SBUS receiver
The picture shows the hardware connection between the SBUS receiver and the ROS control board:
| SBUS receiver | ROS control board |

| + | V |
| - | G |
Experimental phenomenon
After downloading the rosmaster.hex file of the project to the ROS control board, the HT-10A remote controller can be controlled by the joystick after the SBUS receiver is successfully paired.
| HT-10A remote control | Default channel: The remote control does not perform channel mappingDefault channel: The remote control does not perform channel mappingCar function | Car function |
|---|---|---|
| CH1 | Right joystick: slide left and right | Rotate left, rotate right |
| CH3 | Left joystick: slide up and down | Forward, backward |
| CH4 | Left joystick: slide left and right | Move left, move right |
| CH6 | SWB channel | Free stop, brake stop |
Note: If the control direction of the remote control is opposite to that of the HT-10A remote control, you can switch the positive and negative directions of the channel on the remote control.
Set the forward and reverse of the channel

| ① | Up key |
| ② | Down key |
| ③ | Return key |
| ④ | Confirm key |
Press the "Confirm key" on the main interface to enter the settings, and then use the "Up key", "Down key", "Return key", and "Confirm key" to switch different options:
