US firm unveils wheeled humanoid robot with 4-camera vision system

Richtech Robotics has introduced Dex, its first mobile humanoid robot tailored for industrial use, showcased at GTC 2025 in Washington DC. Powered by NVIDIA Jetson Thor and featuring a four-camera vision system, Dex is designed to combine speed, safety, and precision in tasks such as operating manufacturing machines, sorting parts, material handling, quality inspection, and packaging. It comes in two versions: a stationary platform for continuous high-precision work and a mobile platform equipped with wheels for agile movement, boasting a battery life of four hours and a payload capacity of 11 pounds per arm. Dex’s design integrates Richtech’s experience from over 450 robot deployments, merging autonomous mobile robot (AMR) technology with dual-arm dexterity. The robot learns tasks through a "Sim2Real" approach, using NVIDIA Isaac Sim to train in virtual environments before real-world application, enhancing deployment speed, safety, and scalability. Unlike typical humanoids with legs, Dex’s wheeled mobility prioritizes operational efficiency
