Elephant Robotics LIMO Cobot Compound Robot

Elephant Robotics LIMO Cobot Compound Robot

The LIMO Cobot is an autonomous compound mobile robot platform jointly developed by Elephant Robotics and AgileX Robotics. It integrates three core capabilities—mobility, collaboration, and intelligence—into a single desktop-sized system designed for education, competitions, and training applications.

The platform combines two complementary subsystems: the myCobot 280 M5, a compact 6-axis collaborative robotic arm weighing just 850g with a 250g payload and 280mm effective working radius, and the LIMO PRO, an advanced mobile base featuring 4 hub motors with 4 switchable steering modes.

The LIMO PRO incorporates powerful sensor hardware including an NVIDIA Jetson Orin Nano processor, EAI T-mini Pro LiDAR, Orbbec Dabai depth camera, and integrated IMU. These enable autonomous navigation, obstacle avoidance, SLAM mapping, mobile grasping, and visual recognition.

The system's unique 4 steering modes (Ackermann, four-wheel differential, tracked, and omni-directional) adapt to different terrains. The myCobot arm supports various end effectors for precise mobile grasping. The entire system runs on ROS 2 with support for Gazebo, RViz, and Nav2.
