Towards Miniature Humanoid Tele-Loco-Manipulation Using Virtual Reality: A Compliant Full-Body Telepresence Stack for ROBOTIS OP3

Forum topic · 小凯 · 2026-07-24

Summary

This paper presents a compliant full-body telepresence control stack developed from scratch for miniature humanoid robots, making VR-based teleoperation combined with reinforcement-learning locomotion accessible beyond expensive full-sized platforms. Manufacturers commonly pair VR upper-body teleoperation with RL-based lower-body balance and locomotion control, enabling a single remote operator to see, manipulate, and navigate a distant physical environment—but such stacks are rarely available for small, less biomimetic humanoids. The authors demonstrate their framework on ROBOTIS OP3 hardware, achieving walking speeds up to 0.45 m/s independent of arm motion. Tele-loco-manipulation experiments with an expert human operator involved relocating two different 40 g cubes within 10 minutes on average, covering roughly 5 meters of total walking distance. The results show that miniature humanoids can support meaningful teleoperated loco-manipulation, opening low-cost telepresence research to the wider robotics community.

English Translation of Abstract (Summary)

Full-sized humanoid robot capabilities have grown exponentially in recent years, aiming towards general-purpose deployment in human environments. A popular control method used by manufacturers utilizes Virtual Reality for upper-body teleoperation and Reinforcement Learning for lower-body balance and locomotion control. As a result, a single remote operator can see, manipulate, and navigate about a real, distant physical environment. This powerful control stack is often relegated to expensive full-sized robots, many of which are inaccessible to the research community. Miniature humanoids are more prevalent, but employ less biomimicry in their design (e.g. fewer sensors, Degrees of Freedom, etc) and lack similar developments. This paper describes a compliant full-body telepresence control stack developed from scratch for miniature humanoid robots.

Key Results

Framework experiments on ROBOTIS OP3 hardware demonstrated walking speeds of up to 0.45 m/s, independent of arm motion.
Tele-loco-manipulation was demonstrated through cube-relocation experiments with expert human operators.
On average, the teleoperation system moved two different 40 g cubes within 10 minutes, covering a total walking distance of about 5 meters.

Takeaway

The developed system demonstrates the potential of teleoperated loco-manipulation on miniature humanoid robots, extending VR teleoperation + RL locomotion stacks to affordable, research-accessible platforms.
