So since the last post we haven't stop working.
We got interviewed with the local newspaper and so on. http://www.laopinion.com.co/tecnologia/jovenes-cucutenos-crearon-una-mano-robotica-122052
Also, we changed it all up. So no more linear actuators. Yeah we know. For now on we are working with an endless screw moving a gear connected to each finger. Why did we change one of our premises do you ask? well the length of the linear actuator was a big problem for us and the travel or angle of the finger was limited by the length of the actuator.
We changed the software that we used! We used AutoCAD and it was not optimal and expensive. So we opted for Fusion 360 and wao.... what a change. First of all it's just quicker, nicer and easier to use. Normally for a mechanical design we had to print something 5 to 8 times to get it right, now... simulate on the software, modify it, print it and in one go we have it perfect. Highly recommend it.
We are running test with someone. His name is Dario and he happens to have an upper limb amputation. He has been nice enough to try out our hand and so far so good! Now he is the principal motivation to finish it soon. Also he has given us some feed back. like now the fingers have rubber strips integrated to them because the grip wasn't enough for him.
But most important of all, we know you are out there. So tell us what you want to see, what sparked your curiosity to follow this project. If you want us to make a new video or post.... about what it would be?
Happy holidays everyone!
