Ackerman/Differential ROS Car Robot Car Assembled w/ Depth Camera Voice Module N10 Lidar LubanCat 1S

Ackerman/Differential Version:

- The positive Ackerman structure, anti-Ackerman structure, and differential structure can be freely switched by different installation methods
- With differential fittings and a wireless controller
- Including car chassis, STM32 controller, battery, charger, lidar, 7" touch screen (detachable), depth camera, voice module and ready-to-use ROS system

The R550 combines the ideal teaching performance and cost-effectiveness with quality. Equipped with accessories such as a radar and a depth camera, the R550 can be used for mapping and navigation, deep learning, 3D vision, robot formation and the like.

System images for ROS1 melodic, ROS1 noetic, and ROS2 galactic are available.
- Support multi-robot system

Variable chassis construction
Under normal circumstances, if you need to debug the positive Ackerman structure, the anti-Ackerman structure, and the differential car, you may need to purchase 3 cars at the same time. Through the compatibility and replacement of structure and code, our car can realize the functions of the above 3 cars at the same time.

We have worked with Orbbec to create a community of 3D visual developers
The R550 robot is equipped with the achievements of engineers from Wheeltec and Orbbec in 3D visual exploration in the past year. Through the SDK layer development, we have realized advanced functions such as skeleton recognition and somatosensory interaction following.

Robot cluster control algorithm with independent intellectual property rights
Through the combination of the Navigator algorithm and our innovative algorithm, very stable robot cluster (formation) control is realized. This technology has been widely deployed in major universities in China. Users need to purchase at least three robots to achieve robot formation.
