Robotic anthropometric prosthetic appliance of hand with the print of profile on 3D-printer

Robotic anthropometric prosthetic appliance of hand with the print of profile on 3D-printer
Technology description
There is a great necessity to make a prosthetic appliance of limbs for persons with disabilities in Ukraine that is unfortunately increasing due to the events in the east.
It is proposed to develop prosthetic appliance of hand with the following features:
- profile of hand will anthropometrically repeat contours of native hand (through 3D-scanning of healthy hand);
- basis of prosthetic appliance will be printed on the 3D-printer that will provide the highest realism of prosthetic appliance;
- all major joints will bend in the hand (through robotic system with remote control of bends).

The proposed technology cheaper, easier, smaller and more convenient in usage
new in the country
There is an opportunity for practical implementation
The main differences from the prototypes:
- maximally realistic appearance of prosthetic appliance (3D-scanning and 3D-printing);
- imitation of movable joints bends with remote control (robotization of the hand).
Such foreign prototypes, even without 3D-printing, cost thousands of dollars and are almost inaccessible to Ukrainian consumers.

Solved problems
The problem of prosthetic appliances high price remains unresolved for a lot of people with disabilities in Ukraine. The number of such people is only increasing because of events in the east. Recently this question is raised in Ukraine and also abroad. For example:
- "NATO promised to help with prosthetics of 50-ty Ukrainian soldiers" ( - 16.08.2014;
- "Yatsenyuk promised to give money for prosthetics of ATO fighters” ( - 11.08.2014.
Existing primitive prosthetic appliances are far from reality and cause great moral discomfort for people with disabilities. Foreign robotic prosthetic appliances are expensive (thousands of dollars) and, accordingly, will not be practically used by Ukrainian consumers. Besides, even these prosthetic appliances do not imitate native hand profile, which also causes discomfort.
Therefore, the development of domestic prosthetic appliances (with acceptable price) that will be maximally close to appearance of native hand, and which will be able to control the basic bends, is very demanded.

4. Stage of Development
Prototype with favorable lab results and available for demonstration
The product matches to the standards of all electrical, ergonometric and other parameters, so it wouldn’t be difficult to certify products in accordance with technical parameters.
The certification in the Ministry of Health will be needed for the work with people with disabilities at the last step.
The models of 3D-printer and the corresponding control software are developed.
The party of more than 130 control cards of 3D-printer was released based on Altera Cyclone III EP3C1OE144I7N (the price of each card is about $200), that could be the basis of the first experimental complexes for prosthetic appliances printing (at the photo in the end of the innovation submission form).
Several solutions of robotic systems "Hand-manipulator" are developed.
Some processes require improvements: combining of 3D-scanning and 3D-printing processes, including robotic control of hand-manipulator.

There is catastrophic situation with persons with disabilities in Ukraine. The total number of such persons is growing every year and has already more than 2,8 million. ( The necessity of prosthetic appliances is 200 thousand persons. For example, there are 10 thousand disabled persons in the turn of prostheses reception only in the Donetsk region.
Besides, as experts say, Ukraine will soon become a country of young people with disabilities because of military operations at the Donbas - the military hospitals have filled out by 20-years-old guys with hands and feet amputations ( /forum/ukraina/daesh-pobedu_.htm).
In addition, the government purchases of prosthetic and orthopedic products were greatly cut back because of lack of money.
Thus, the Ukrainian market of prosthetic products has the urgent need of any and especially high-quality products. And this trend will only increase considering the increase of the number of people with disabilities, and continuing military actions.
If we take the cost of hand prosthetic appliance about 20 000 UAH (practically the lowest price of a usual prosthetic appliance) and multiply by the required 100 thousand persons with disabilities of upper limbs (half of 200 thousand that are required the prosthetic of all limbs), then the total market volume in Ukraine will be about $ 2 billion UAH.
Competitors, substitute goods, entry barriers
Foreign analogues (with the price of ten thousand dollars) are not considered here as prototypes because of its high expensive.
There are several companies in Ukraine in sphere of upper limbs prosthetics: "Ortoteh-Service GmbH Ltd." (Kiev), GE SRI "Elastic" (Kiev), Ukrainian Center of Afghanistan veterans rehabilitation Ltd. Specialized orthopedic enterprise "AE.Brik" (Kiev ), GE Vinnizkoe orthopedic enterprise, PO Lvovskoe state experimental enterprise of vehicles and prosthetics (Ukrprotez) and others.
The products that are the closest to the prototype are manufactured by the "Center of prosthetics “Edwards" (Kiev) (
- prosthetic appliance of wrist only - 22 000 UAH – implements functions of the object capture and holding; the wrist is driven by a bandage that is fixed on the shoulder girdle;
- prosthetic appliance of hand with a myoelectric control - "system MYOBOCK» - 83 000 UAH - with muscle contraction they give alternating voltage that is perceived by the skin with the help of control electrodes; the electronic amplification system that is installed in electrodes allows to turn on and turn off the electric motor even with insignificant contraction.
The idea of limbs 3D-printing has already widely developed today:
- the United States (Washington): "Father has made the 3D-printer prosthetic hand for his son” (;
- the boy from Vinnitsa - experiment channel ICTV: “3D-Printed hand for a child's dream” (
However, no one has been combined 3D-scanning, 3D-printing and robotic management yet.
Copying and implementation of the proposed idea are theoretically possible. However, each of indicated firms specialize in particular separate direction - for example, prosthetics, and does not own a technology of 3D-printing or robotic control.
Besides, a significant feature of the project is the necessity of its revision according to scientific and technological innovations that are not belonging to the above-mentioned companies. Only this creative team that is presented on the competition, which combines the developers of several necessary areas, will be able to finalize and implement the proposed project.

Risks of the project and anti-risk activities
Project risk (political):
Implementation of the project depends on the foreign companies’ products purchases, approximately Chinese manufacturers: servos, plastic for the 3D-printer components, and so on. It is possible (but improbably) the appearance of difficulties in the constitutive elements purchasing due to variety of political and economic reasons.
Risk aversion activities: all constitutive elements, although more expensive, but are completely interchangeable by European manufacturers (German servomotors, French microelectronics, etc.). At the worst, almost all components, although lower quality, can be found at the Ukrainian market.
Risk of the project (technological):
The project needs finalization - combining 3D-printing with robotic part of the project. It is possible the appearance of some unexpected technological problems at the stage of finalization.
Risk aversion activities: the presence of a broad team of developers from different cities (Kiev, Kharkov, Nikolaev) and different areas (research and production) suggests the possibility to solve any possible technological problem.
Project risk (consumer behavior):
This type of product is new at the Ukrainian market. The customer can doubt about the necessity of such products purchasing and focus on the already tested less functional products or more expensive foreign analogues.
Risk aversion activities: the proper advertising strategy, the involvement of various foundations and non-governmental organizations which are working with disabled people will help to solve this problem.
Risk of the project (the immaturity of the market):
Some failures are possible at the first stage of products implementation that will require the modernization and improvement of prosthetic appliances. The lack of a broad service network can restrain consumer interest to these products.
Risk aversion activities: it’s possible the involvement of existing electronics service centers. In this case, it is require the development of additional documentation for service centers.
