Ackerman ROS Car Robot Chassis Assembled For Jetson Nano B01 RPLIDAR A2 Normal Type Load 10KG

Ackerman ROS Car Robot Chassis Assembled For Jetson Nano B01 RPLIDAR A2 Normal Type Load 10KG

Description:
The Ackerman robot uses rubber wheels, which can be used in indoor and outdoor environments. The front wheels are equipped with a steering mechanism, and the rear wheels are powered by dual motors, and the front wheels are steered through a differential.

Our robot car is equipped with an aluminum alloy base plate and a coaxial pendulum suspension system, which can adapt to uneven bottom surfaces.

Advantages:
- Photoelectric encoder
- Planetary gear motor
- Lidar navigation
- ROS operating system
- Open source full set of materials
- Built-in PID controller
- For FreeRTOS system
- Can be controlled by CAN/serial port


Attention:
- The main difference between the normal type and the heavy-duty type is the motor reduction ratio, which results in a difference in speed and load.


Suggestions For ROS Master Selection (basically the same, use the system for Ubuntu):
1. Generally, you can choose version for Raspberry Pi for starter, here is 2GB, because the version for Raspberry Pi is not cost-effective to increase the memory, so it is better to use version for Jetson Nano.
2. Version for Jetson Nano upgrades the GPU, which is a bit better than that for Raspberry Pi in terms of image processing and simple deep learning.
3. The performance for Jetson TX2 is very powerful, especially in deep learning, the overall performance is qualitatively improved compared to the other two models. You can also customize i5, i7 and other industrial computers as ROS master control, and you can contact customer service for customization.
