Some things you should know about Robohand devices

Robohand uses 3D printing to provide functional, safe, cost effective upper extremity assistive devices to help enable any individual with an upper limb difference.

Overview and Expectation of Robohand devices:


Assessment Criteria


Robofinger(The Tradesman Finger) If people are missing the PIPJ[1] & DIPJ[2]  then your MCP[3] (knuckles) needs to have equal to or greater than 300 (degree) motion Improved Fine Motor Skills
Robohand If people are missing all or partial fingers and/or partial hand, your wrist needs to have equal to or greater than 300 (degree) wrist motion) Provides gross grasp (All fingers open/close together)
Roboarm If people are missing fingers / hand and wrist your elbow needs to have equal to or greater than 300 (degree) motion Gross grasp as above with palm up and down capabilities

Functionality – The design of Robohand uses the motion of existing joint(s) to mechanically move (or drive) the custom made device. Robohands are not myoelectric[4] and do not require invasive surgery. Nor do they have motors or battery packs that add weight, require maintenance and increase cost.  They are environmentally friendly as the PLA they are 3D printed with is biodegradable.


Safety – Robohand creator, Mr. Richard Van As, has dedicated much of his personnel time, energy and financial resources to further his personnel belief that his inventions “DO NO HARM”.

Robohand uses medical Orthoplastic that is custom molded to the wearer to limit the possibility of skin lesions, infection and injury. The Orthoplastic used by Robohand is breathable, washable and medically approved for this type of use.

A Robohand device is custom fitted which adds to client comfort. A proven statistic is 25% of people with prosthetics do not wear them due to the fact they are uncomfortable. Using medical Orthoplastic ensures Robohand will remain medically fit for use and long term wear.

Robohand uses stainless steel hardware that is less likely to fail or break, does not rust or discolor and decreases the risk of infection/injury. Dome nuts are used to decrease the likelihood of injury to yourself or others. Stainless steel is more medically appropriate than cheaper hardware. Many of our clients like to swim and bathe in their Robohands and the stainless steel does not rust or discolor.


Cost effectiveness – Every effort has and will continue to be made to keep Robohand devices cutting edge with innovative designs to increase function and manage cost while maintaining Robohand’s devotion to high product standards with the safest materials available.

Robohand’s mission is to help enable people with an upper limb difference, be more independent and interact with the world so that they might live a full and joyful life.

[1] PIP: Proximal Interphalangeal Joint – this means the middle joint of your finger

[2] DIP:Distal Interphalangeal Joint – this means the end joint of your finger

[3] MCP: Metacarpal Phalangeal Joint – the joint between your hand and finger (knuckle)

[4] Myoelectric definition: A prosthetic control technique which utilizes skin surface EMG muscle potentials for the actuation and movement of an electric powered prosthetic component)

Why Robohand – Open Source design for customised, fitted, mechanical fingers and hands.

Waldo Loves Robohand

Since mid 2011, we have been on an adventure to create mechanical fingers that can replace lost digits.

Through research and development we have discovered that there are no functioning replaceable digits that don’t cost the earth. If you cut off your whole hand there are prosthesis widely available to you, but if you lost your fingers there are no replaceable digits.

Follow our Journey of self discovery as well as the incredible work done to create fully functioning mechanical fingers for the lay man and hands for children. The first ever in the world!

We have published this as open source so there is no patent and the design is available for free.

    Open Source + 3D-Printing = (Industrial) Revolution. Good luck!

    Hi — I have just learned about an 8-year-old girl in an orphanage in Cameroon who is missing both of her hands due to an accident when she was very small. I’m not sure whether the robohand would work for her because I’m not sure she has enough of her hands remaining. (I have photos, and my contact has x-rays.) I also don’t know how she would get to an occupational therapist to have gauntlets made etc. Do you have any recommendations for how I could get started finding out whether she is a reasonable candidate for robohands?

    (I think this is a more appropriate place for my question.)
