Handroid

Handroid is a wire-driven next-generation electric artificial limbs.
The newly developed control method is very easy to use and the artificial limbs,designed based on X-rays of human limbs, are functional and well-designed.
We incorporated the opinions from medical experts and designed the limbs to be suitable for the user’s life environment.
The thumb is manual with a 2-axis motion range, and the other 4 fingers move with an electric motor.
Moreover, the featured wrist joint provides a high degree of flexibility.
Therefore, it is able to firmly hold objects, adjusting to the shape of the object.

A real artificial hand Handroid is realized by real skin and real fingernails.

In a conventional artificial hand, fingers are spread and closed and by myogenic potential signals caused by the contraction of a muscles.
It is difficult to control the motion of fingers.

Fingers of Handroid are spread and closed by the rotation of person’s wrist.
It is very easy to control the motion of fingers.

Sensors are attached to a wrist of a person who lost his hand.

Handroid is worn on his wrist.
Handroid has been selected and bought by some universities, research organizations, and makers.

2ndroid

1. Two fingers open/close (resin・non-slip finishing)
2. Wrist joint (tilt-featured)
3. Expansion and contraction (Aluminum・carbon fiber, internally-located screw mechanism) Stroke width 40cm
4. Controller (Blue button・opening and closing fingers) (Red lever・tilting)
5. Grip (switch for expansion and contraction) There are various sizes and configurations for the existing “Magic Hands”, but most of them only have a single feature; opening and closing the clicks. They are cheap and absolutely responsible for the usage by an able-bodied person. However, they usually do not have wrist joint feature, and, if a user is seated in a wheelchair, he sometimes cannot grab objects as the clicks cannot be leveled if he has to hold the Magic Hand higher than his shoulder level. Robot arms attachable to wheelchairs have been developed worldwide. Some have been put to practical use, but impractical as they are very expensive. We have therefore developed the “2ndroid”, implemented the re-examination of the concept of the Hand Arm with the investigation of the market and users’ needs.
