Dobot X-Trainer Robotic Arm

The Dobot X-Trainer is a dual-arm teleoperation system for embodied-AI research. You demonstrate a task by hand, and it records the data you need to train a robot to do it by itself.

An operator moves two 6-DoF leader arms, and two Nova 2 collaborative arms with grippers follow in real time. Three depth cameras, at the grippers and overhead, capture the scene while the system records joint angles, gripper actions and RGB-D images at 25 Hz. Dobot's SDK covers the full loop: data collection, model training and autonomous inference. Dobot says this approach cuts imitation-learning training time by 70%, with tasks such as folding clothes trained in about two hours.

Each follower arm carries 2 kg over 625 mm, on a fixed 290 kg base. A training PC isn't included: Dobot recommends an NVIDIA RTX 4090-class workstation, and Scan can supply a matching 3XS AI workstation. The X-Trainer suits university labs, AI research teams and companies building manipulation models
