Well a prototype is also meant to test out an idea, where cardboard, stiff paper and any material less than the strength of the final product will not give an accurate presentation of what may happen with the final product. The aluminum I am using is stronger than the stock aluminum and I will be using the same stuff for a final production. Which is why for example, I show that one can still climb (granted it was just a picture, but i assure you it could climb) ,but at least hold the entire weight of the RN on a rope. I can punch and it is very strong, showing that it is a plausable idea. I have not included your name in my presentation, I have not sent you any hate mail, and I do not hate you. Even if i did, its the internet, these are forums, everyone is here to learn. The aluminum I bought (from enco) cost me $8 for a 12 by 24 in. sheet. The tools, albiet rather expensive, do not really play into the cost as I can make as many parts as i want at a very minimal cost. The blades on the scroll saw cost pennies, so it's easy to pay that off. And the main reason I come here and work with robots? Simply to learn. I learn from fabricating aluminum parts, designing and redesigning. It's not just something fun to do. (but it is rather fun
I'm sorry you recieve hatemail, that is not my fault, but it is unfortunate.
Pev, I actually have not tried the 'thumb' being in the center, but one could imagine that it may be more stable(not sure either way). After attaching the 'thumb' where I did I noticed it was very stable and have proceeded with it from there. My original idea was actually to have six fingers and use another 'thumb' on the other side.
But I like the idea of keeping the hand humanlike, although if performance was a huge issue I would consider moving it. If that were the case I may convert to having three fingers on the top, and two on the bottom (even more gripping space). Or perhaps my original idea.
thanks to everyone who likes my claws!
