4WD ROS Robot Chassis 4PCS High Torque Encoder Motor Pneumatic Tire Chassis with STM32 Electric Control Kit

4WD ROS Robot Chassis 4PCS High Torque Encoder Motor Pneumatic Tire Chassis with STM32 Electric Control Kit

Description:
- This series of chassis is equipped with STM32 chassis control board (optional), which supports chassis control through serial port. The STM32 chassis control board integrates a 9-axis IMU, and the chassis is driven by a high torque encoder motor, which can feedback tire speed and has a load capacity of 15kg. Combined with the ROS driver we provide, it is very suitable for the development of ROS robots.

Chassis Technical Parameters:
- Chassis size: 420 x 396 x 190mm

- Endurance: no load ≥ 3 hours
- Maximum speed: 1m/s (adjustable)
- Chassis net weight: 11kg
- Load capacity: 15kg
- Wheel: 150mm pneumatic tire

Electric Control Parameter:
- Control method: serial port, Bluetooth APP control
- Gyroscope: 9-axis IMU
- Communication contents: speed control, speed feedback, battery voltage feedback, IMU data feedback
- Resources: STM32 source code, ROS driver, 3D model
- Reserved voltage: 1-channel 24V, 1-channel 5V (reserved bottom control board)

Chassis Structure:
- The chassis is reserved with mounting holes for SLAMTEC A1 radar and ORBBEC depth camera, as well as mounting holes for Jetson NONA and Raspberry Pi, making it easy to expand into ROS robots.
- The chassis is reserved with one 24V interface (24V 2A) and one 5V interface (5V 2A) for convenient power supply to upper level equipment.

Providing ROS Driver:
- In the system for Ubuntu ros, by directly calling the ROS driver we provide, it is possible to achieve communication control of the chassis through the serial port, thereby controlling the motor.
- The chassis serial port adopts Type-C interface, which is convenient to use.
