Product Overview

Robohands are mechanically driven assistive devices.  This means Robohands use movement of existing joints to mechanically flex the Robohand fingers and thumb. The result is a “gross grasp” this means all fingers and thumb open and close at the same time. Robohands are great for riding bikes, holding baseball bats, and gripping objects. This can free up the other hand for tasks like cutting out a shape with paper and scissors, or holding your lunch box while you get on the bus. A Robohand can not move fingers or thumbs individually.

The mechanical parts of a Robohand device are made via 3D printing. The 3D printed parts are properly sized, assembled and attached to custom molded orthosis. Custom molded orthosis are the safest, most hygienic, comfortable and effective way to transfer movement to the Robohand. Robohand strongly believes that the custom molded orthosis are, by far, the safest and most efficient use of the Robohand design.

The creator of Robohand, Mr. Richard Van As, has intentionally designed Robohand’s to be mechanically driven to avoid batteries, surgeries, added weight and cost. Robohands can get wet allowing use for things like bathing, washing and getting in the pool!

By using 3d printing technology and Mr. Van As’s designs, a Robohand can be fabricated at a fraction of the cost of a conventional prosthetic. While Robohands do not attempt to match the aesthetic qualities of some conventional prosthetics, a properly fabricated and applied Robohand, is highly functional for gross grasp. Robohands can easily and inexpensively be repaired or updated for growing children.

The high cost of conventional prosthetics usually necessitates that they are purchased toward the end of a child’s physical development. This delay is less then ideal. A child’s young brain is highly plastic and develops to meet their daily needs early in life. The skills of functional/spacial awareness using a device, bi-lateral tasks (integrating both sides to accomplish goals), gripping and holding are easily developed and maintained by young children. These skills will be a struggle to acquire later in life with a brain that is inexperienced with the use of an assistive device. An important advantage of Robohand’s low comparative cost is that it can enable families of young, limb deficient, children to acquire an assistive device while the child is growing.

In summary Robohand devices can be a cost effective alternative or compliment to commercial prosthetics, providing a functional grasp for “work horse” tasks. Robohand use allows the wearer to get dirty and wet. If broken they are cheaply repaired. Robohands are also an excellent “starter” device for growing children.
