Its design emphasizes clear perception and reliable interaction. Roban2 uses a multi-sensor vision system that helps it recognize people, objects, and spatial layouts. As a result, it can handle common navigation tasks with fewer errors, even when the environment changes. Moreover, its communication tools allow teams to operate and monitor the robot with ease, which improves coordination and safety.
Roban2 also supports a variety of manipulation tasks. Its multi-joint arms and dexterous hands give it enough flexibility to grasp everyday items, sort objects, or support structured demonstration tasks. While it is not built for heavy lifting, it performs well in accuracy-focused roles. Therefore, it works especially well in labs, robotics classrooms, and teleoperation training setups.
