SLAMTEC RPLIDAR Al Series
Equipped with new genuine Lidar

Based on our excellent and concise mechanical design, the lidar can be 360° unobstructed Make the robot have a better effect when following and navigating

The camera angle can be adjusted greatly

Whether it is patrolling, following, visual slam, etc., it can be adjusted to a suitable angle, and the camera is placed on the front of the car without obstruction

Hall encoder

The encoder has a pull-up output, which is pulled up to the power supply VCC pin by default, which can be directly collected by the single-chip microcomputer

BATTERY DESCRIPTION

Due to overseas shipment issues, no batteries are prepared Please prepare 11.1V lithium battery by yourself

INTERFACE DESCRIPTION

CAN: The mobile platform can receive commands from the CAN port and send its own data (odometer and IMU) through the CAN port.
Serial port: The mobile platform can receive commands from the serial port, or send its own data (odometer and IMU) through the serial port.
USB interface: used to connect to a computer, download the program with one key, receive command control sent by the computer, and send its own data (odo meter and IMU) to the serial port.
Bluetooth (or WiFi): can send its own information to APP, can receive APP remote control commands, and can adjust PID parameters.
PS2 interface: Provide PS2 handle socket, provide code plug and play.
SWD interface: SWD interface is provided for online debugging.
