Why can’t I find all the other cool things for a Robohand on Thingiverse?
Our original design of a functional mechanical hand was shared publicly and will remain open source for anyone who has the capabilities to create their own Robohand. Our new designs will not be shared publicly as we have discovered that people are doing things with Robohand that are not safe or to the Robohand standard, so they will remain the Intellectual Property of Robohand.
I am confused about the price of a Robohand. Some people say it costs US$5.00 to make. How much does it cost to make a Robohand?
To print the fingers with the knuckle block and hinges for a Robohand costs around US$5.00. To make a proper Robohand, which includes medical Orthoplastic, stainless steel hardware, tools, Velcro, plus the time it takes, costs US$2000.00. When Robohand has charged for a hand we have only requested US$500 which covers only the cost of materials.
What is Orthoplastic and why shouldn’t I use anything else?
Orthoplastic (Thermoplastic) is moldable, breathable, washable and medically approved for this type of use. It is custom molded to the wearer to limit the possibility of skin lesions, infection and injury, which adds to client comfort. Using medical Orthoplastic ensures Robohand will remain medically fit for use and long term wear.
I have seen some Robohands without the stainless steel hardware. Why is that?
The Robohand that does not have any stainless steel hardware was developed by Michael Curry from Makerbot and is a click/snap together version. This snap together Robohand was developed for demonstration purposes. This snap together Robohand does not have the same functionality or robustness as Robohand and it is not recommended to make this snap together Robohand as a prosthetic/mechanical device. It was also published as open source so enthusiasts could take the design and make improvements.
Where can I buy the stainless steel hardware?
You can purchase the stainless steel hardware through Robohand. Contact us via our website. Note: you will be required to pay for shipping as well as the cost of the kit.
What is a Snap Together Robohand?
The snap together Robohand was developed by Makerbot and is a click together version. This snap together Robohand was developed for demonstration purposes. This snap together Robohand does not have the same functionality as Robohand and it is not recommended to make this snap together Robohand as a prosthetic. It was also published as open source so enthusiasts could take the design and make improvements.
Can I make my own Robohand?
Yes. If you have access to a 3D printer you can print the hand. If you can source the hardware and Orthoplastic, there are assembly manuals on Thingiverse that can assist you.
Who is Ivan Owen?
Ivan Owen was a collaborator on Robohand and assisted with design details and 3D scripting. It was a personal decision of Ivan Owen to no longer be part of Robohand and he has focused his energies elsewhere.
How soon after an injury can I get a Robohand?
Each person is different, however, we recommend that you wait until your wound has healed completely, you do not have any sensitivity and the swelling has passed. You would be required to have an assessment before becoming a candidate.
At what age can I get a Robohand?
With smaller children, we recommend between the ages of 2-3 years old. This will also depend on the size of the hand that is required, as we cannot make them too small as they lose functionality.
You are never too old to receive a Robohand either.
How do I know if I am a candidate for a Robohand?
You need to have equal to, or great than 30 degree motion in your wrist. As per question 13, your injury must have healed completely; there must be no swelling or sensitivity to touch. You would be required to have an assessment before becoming a candidate. See the post on Things you should know about Robohand.
How many fingers must I be missing before I can get a Robohand?
If you are missing only one finger, you will be assessed for a Robofinger.
If you are missing more than one finger, you will be assessed for a Robofinger or a Robohand.
If you are missing all your fingers, you will be a candidate for a Robohand.
I don’t know anyone with a 3D printer. What is the process to get a Robohand from Robohand?
Please send us an email to firstname.lastname@example.org. You will be issued with a form to fill out and return to us. There after we will conduct an initial assessment.
What is a Roboarm?
If your amputation is from above your wrist you would likely be a candidate for a Roboarm. This will require that you have a small amount of your arm intact below the elbow and your elbow has a minimum 30 degree bend motion.
If your amputation is above the elbow you will need a physical assessment to establish how to attach and drive the Roboarm.
What is a Robofinger?
The Robofinger was designed with the Tradesman in mind. It needs to be strong enough for the individual to do physical work. The original Robofinger is CNC machined in aluminum. However there is a 3D printed one available.
