Welcome, Linker Hand L20!
The Linker Hand L20 is a robotic hand from LinkerBot, a Chinese robotics manufacturer. Its overall Humanoid.Guide Hand Score is 6 out of 10, placing it in the capable category rather than the highest performance tier. The rating combines 4 out of 5 for Degrees of Freedom with 2 out of 5 for Strength, giving the hand a profile that favors dexterity over strength within this scoring system. These are category ratings, not measurements of joint count or physical force. The mechanical design uses brushless motors, precision ball screws, and a rigid linkage transmission instead of tendons or cables. It has five fingers and a listed weight of approximately 1.2 kg. Electrical specifications include a supply range of 24 to 48 volts, with CAN or RS485 interfaces for connection to a robot controller. Together, these details describe a substantial robotic hand with a distinctive transmission architecture and a stronger rating for freedom of movement than for strength.
The clearest way to interpret the L20’s technical positioning is to keep its two category scores separate. Its Degrees of Freedom rating of 4 out of 5 places that aspect near the top of the scale, while its Strength rating of 2 out of 5 sits in a lower tier. The overall score therefore should not be read as evidence of equally strong performance in every dimension. For an engineering comparison, the L20 is more compelling when dexterity carries greater importance than achieving the highest strength rating. These scores provide a useful initial comparison framework, but they are not interchangeable with physical specifications or validation for a particular application. Application selection still requires matching the hand’s documented specifications to the intended task.
The Linker Hand L20 is listed as in production, with an advertised price of USD 4,200 and an option to inquire about pricing. LinkerBot is based in China and also offers the smaller Linker Hand L6, positioning the L20 within a broader family of robotic hands rather than as an isolated product. Prospective buyers can contact the manufacturer through www.linkerbot.cn to discuss purchasing and integration requirements. Its broader significance lies in the combination of an established production listing, a clearly identified mechanical architecture, and a score profile that distinguishes dexterity from strength. That distinction supports more meaningful comparisons than treating every robotic hand as equivalent simply because it has a familiar humanlike form.
