One of the interests of the OpenProsthetics Project is to develop low cost prototyping platforms to encourage experimentation and collaboration on both control systems and mechanisms. One of our favorite prototyping tools is the LEGO construction system. We think that LEGO parts can offer a flexible and inexpensive method for developing complete mechatronic devices for research made great progress in developing advanced mechanisms for a LEGO complete with fully articulated fingers and opposable thumbs at a scale similar to that of the average male hand. He has put together some great documentation of his construction techniques for the basic this hand isot. John has been working on a next revision of the device that includes a functional wrist with cable actuators. We encourage others to look at design and consider collaborating with him to continue the development of this platform. Once a functional power system is integrated the device could serve as an excellent plant to be controlled by a low-cost myoelectric or acoustic myography sensor a structure like this together could make it strong enough even for limited use. Experts say that Oatey All-Purpose Glue works well. We have yet to give it a try although we can say that it can be frustrating to have a model come apart when you try to use a LEGO-based sensor platform is another area of interest. We believe that a low-cost myoelectric sensor system could be built using LEGO Mindstorms NXT controllers. Creating a NXT-based sensor platform combined with a hand mechanism such as would result in a complete LEGO-based reference design for less small number of upper-extremity a toy that uses myoelectric technology could spur some interesting developments. LEGO products are accessible in ways that many things in the world of hardware are not. The existence of a complete myoelectric platform like this would significantly lower barriers to participation in research and development and aid in accelerating collaboration by using readily available parts for LEGO hand show here for the first time in April has undergone some improvement. Advancements ofote include articulation and the wrist now moves naturally. I have not yet acquired any motors to actually move it, but the hand will function by hand. I will be tearing it down at some point here to facilitate making instructions. Articulations are done with zip ties. After extensive testing with cables and wire I thought I would mimic nature. The result has been very good as the zip ties act very much like real tendons. The wrist functions of the same principle as a real one. The two support bones twist from an axis to the elbow joint. The next adventure will be figuring out to power out the video
