Tokyo Robotics Inc. is a Japanese robotics company founded in 2015 by Yoshihiro Sakamoto, specializing in the development of torque-controlled [[humanoid robot]]s and robotic hands. Based in [[Tokyo]], [[Japan]], the company produces the [[Torobo]] humanoid robot and the Torobo Hand, designed for research, manufacturing, logistics, and service applications. Tokyo Robotics' approach centers on high-performance torque sensing and impedance control throughout the robot's body, enabling safe and skillful task execution.
Tokyo Robotics was founded in 2015 by Yoshihiro Sakamoto in Tokyo, Japan. The company was established to commercialize advanced torque-controlled robotics technology for both research and industrial applications.[1]
The company developed the [[Torobo]] humanoid robot as its primary platform, featuring torque sensing in every joint and impedance control throughout its body. This approach enables the robot to perform tasks safely in close proximity to humans while maintaining the dexterity needed for complex manipulation.
Tokyo Robotics planned to launch a new version of Torobo in Japan by March 2025, with an international release scheduled for October 2025.[2]
In 2025, Tokyo Robotics released a demonstration of Torobo autonomously wiping a table using Deep Predictive Learning, a neural network-based approach that enables the robot to predict and execute cleaning motions without explicit task programming.[3]
On April 2, 2026, Tokyo Robotics officially entered the race for bipedal locomotion, showcasing a prototype capable of human-like walking, dynamic push recovery, and high-fidelity whole-body teleoperation. This represented a significant expansion from the company's previous focus on upper-body manipulation.[4]
The [[Torobo]] humanoid robot is Tokyo Robotics' flagship platform.

Torobo's software stack is built on [[ROS]] (Robot Operating System) and includes:
Tokyo Robotics also produces the Torobo Hand, a dexterous robotic hand designed for manipulation research and applications. The hand features torque-controlled fingers for compliant grasping.
Tokyo Robotics' core technological differentiator is its approach to torque sensing and impedance control throughout the entire robot body. Every joint in the Torobo platform includes torque sensing, enabling:
In collaboration with research partners, Tokyo Robotics has implemented Deep Predictive Learning on the Torobo platform. This neural network-based approach enables the robot to predict the sensory consequences of its actions and generate smooth, autonomous cleaning and manipulation behaviors without explicit task programming.[3]
In April 2026, Tokyo Robotics demonstrated reinforcement learning-driven bipedal walking capabilities, including:
