Welcome, CR Hand!

CR Hand is a compact robotic hand from Curious Robotics, a company based in Chiba, Japan, developed for education and research. Its listed price is USD 1,500, positioning affordability as a central part of its design. The human sized assembly weighs 326 grams and uses high precision FDM printed plastic for its main structure. Six servo motors and a Pololu Micro Maestro controller are integrated into the hand, keeping the control hardware within the assembly rather than in a separate external enclosure. Its overall Humanoid.Guide Hand Score is 3 out of 10, placing it in the developing category rather than among mature or leading systems. The component ratings are 2 out of 5 for Degrees of Freedom and 1 out of 5 for Strength. These are comparative tier ratings, not physical measurements or joint counts. Together, they describe an accessible research product with modest dexterity and a lower strength rating, making realistic expectations important when considering it for a laboratory or classroom.

For education and research, CR Hand offers a concrete subject for examining how robotic hand designs balance dexterity, strength, weight, and cost. Its Degrees of Freedom rating of 2 out of 5 and Strength rating of 1 out of 5 provide useful starting points for comparison with other hands, but neither rating should substitute for an application specific evaluation. Teaching discussions can distinguish joint architecture from independently controlled motion, and strength ratings from measured force under defined conditions. Research planning can likewise separate the purchase price from the wider requirements of an experimental setup. This framing keeps attention on measurable requirements rather than treating an overall score as proof of suitability for a particular manipulation task.

CR Hand is listed as in production, with a displayed price of USD 1,500 and an option to inquire about pricing. Curious Robotics is the manufacturer, and its location in Japan places the product within that country’s robotics development landscape. Its broader significance is its emphasis on an affordable, compact platform for education and research rather than premium performance positioning. For prospective buyers, the listed price is one part of a purchasing decision that should also account for application requirements, integration work, and experimental objectives. The combination of a lightweight printed structure and integrated control hardware illustrates a practical product design approach, while its developing overall rating keeps its market positioning grounded.
