Ti5ROBOT Introduces Compact Robotic Hand ‘Cool Hand’

On September 14, 2026, humanoid.guide introduced Ti5ROBOT’s compact robotic hand, Cool Hand. It measures 205×132×80 mm and weighs 0.48 kg. The hand is designed for humanoids, prosthetic hands and research settings.

Its compact size — 205×132×80 mm and 0.48 kg — highlights the design constraints involved in mounting a hand at the end of a humanoid arm. If Ti5ROBOT’s claims are accurate, evaluating the hand will depend less on its appearance and more on how easily it can be implemented with its control and sensing systems.

Cool Hand should be viewed first as a compact hand geared toward integration and prototyping, rather than as a finished, high-output product. Its dimensions of 205×132×80 mm and weight of 0.48 kg reflect design considerations for mounting it at the end of a humanoid arm. Its six electric actuators and tactile and force sensing also suggest that it is intended as an input device for manipulation research, rather than a simple gripper. However, with a Humanoid.Guide score of 3/10, a degrees-of-freedom score of 2/5 and a strength score of 1/5, it is reasonable to regard it as a product in development rather than a completed high-functionality hand, based on the information available. Publicly available information suggests that humanoid hands often have to balance three factors: low weight, grasping performance, and ease of use in prosthetic and research applications. Cool Hand appears to prioritize low weight and ease of integration, possibly at the expense of output and dexterity. The key question is how well the company’s claims can be reproduced in real-world environments; see the original source for details. From an industry perspective, the hand’s value appears to depend not only on its standalone performance but also on the integration of motion sensing, torque control, and tactile and force sensing. This is a field where product competitiveness is determined by the combination of mechanical components, controls and sensors, and where the number of components and control complexity could affect implementation costs. Public information does not confirm the price, replacement parts, durability or connection specifications for existing humanoid platforms, so the basis for comparison remains unclear. Three points warrant attention going forward. First is the sale price and supply model. Second is the actual payload, grasp stability and durability test results. Third is compatibility, including which robot platforms and research applications the hand is tested with.

For Japan’s prosthetic-hand and robotic-hand sectors, key issues often include how to package lightweight designs, fingertip control, and tactile and force sensing. If more products like Cool Hand emphasize compactness and integrated sensors, domestic companies that separately supply mechanical components, sensors and control software will need to focus on compatibility with connection specifications.
