Why LIMO： Open-source, 4 steering modes, programmable, high-performance sensor systems powered by Nvidia Jetson Nano(4G), multi ports for extensive design needs.
Four steering modes make LIMO substantially superior to other robots in its class. The available modes are: Omni Wheel Steering, Tracked Steering, Four-Wheel Differential Steering and Ackermann Steering. Switching between modes can be completed in just 3 mins and they can meet the requirements for different environments including indoor and outdoor scenarios.
LIMO comes with a specially designed simulation table that can help you quickly simulate and test the developing functions in the most realistic scenario possible.
