The DEEP Robotics Lite3 is a compact quadruped robot designed for research and education. Standing approximately 610 by 370 by 406 mm and weighing 12 kg, it offers 12 degrees of freedom across four legs and achieves 4 m/s top speed, 40-degree slope climbing, 18 cm stair navigation, and a 5 kg continuous payload. Powered by an RK3588 processor with 1 kHz control loop, it runs for 1.5 to 2 hours with a 5 km range from a hot-swappable battery. It supports ROS1 and ROS2 with full SDK and API access for secondary development, reinforcement-learning-trained gaits, and complex maneuvers including jumps, flips, and self-recovery. Available in Basic, AI, Venture, Pro, and LiDAR editions with varying sensor and interface options for academic and R&D applications.
