TECH – A Tokyo‑based startup, H2L, has launched a groundbreaking innovation known as the Capsule Interface, enabling users to control humanoid robots remotely using nothing more than their own muscle movements. Unlike traditional systems that rely on cameras or wearable motion trackers, this technology taps directly into real-time muscular tension—capturing both actions and intent, effectively transforming the human body into a living remote control.
Encased like a massage chair, the device is embedded with ultra‐sensitive muscle sensors. These detect even minute changes in muscle strain, transmitting data about movement and force to a robot such as the Unitree H1 humanoid. In demonstration footage, a woman seated comfortably within the Capsule effortlessly guides the robot through tasks—lifting boxes, cleaning surfaces, and engaging with another person. The key innovation lies in the interface’s ability to relay not just motion but the effort behind it, enhancing teleoperation with genuine physical awareness.
“Motion data alone is not enough to achieve a realistic level of emotional and physical interaction,” H2L explains, stressing the critical role of force mapping to create an authentic and immersive control experience. By preserving force dynamics, the technology bridges the gap between mimicry and truly sharing one’s physical presence via a robot.

The Capsule Interface opens up diverse applications—ranging from remote business meetings and telework to logistical operations in hazardous environments. For instance, delivery workers could manage loading and unloading remotely, while medical personnel could perform delicate procedures without exposure to risk. The system can also benefit elderly care, domestic chores, farming, and virtual avatar control in entertainment or education settings.
Importantly, H2L’s device is designed for ease of use and accessibility. It requires neither specialized training nor cumbersome wearables. Instead, it offers a natural interface seamlessly integrated into chairs or beds, catering to users who may have limited mobility. Looking forward, H2L plans to introduce proprioceptive feedback, which would allow users to feel what the robot senses—creating a two‑way flow of physical interaction and vastly enhancing immersion and empathy in remote collaboration.
With its blend of real-time muscle sensing, intuitive design, and broad use‑case potential, the Capsule Interface marks a major step toward human–robot synergy. It paves the way for fully embodied telepresence, where users can remotely work, care, or simply connect through robot surrogates—and feel as if they themselves are present.
