Throughout this week we've been looking through lots of different types of robot hands. Before we settled on the 3D printed hand from Thingiverse, here a few of the things we looked at:
The first thing we heard about was a 'grabber' that apparently Professor Jarvis had. Prof. Russell told us that it might still be in his office, or that Tom Drummond might have procured it. However, when we went to check, neither Tom nor the room had this thing. Instead, we talked to Andrew in the workshop and he showed us that there was a 4M toy robot hand which was probably exactly the same thing we were looking for:
As you can see here, there are only three controlling fingers for the five fingers - this is due to the fact that two of the wires are connected to four of the fingers. Andrew told use he would be able to re-wire it if we were able to buy it. We found, however, that we would be able to do it cheaper!
The next idea we had came from this picture:
This is piping that has some 'hinges' or 'joints' cut out of it, and wires threaded through to control the hand. This seemed to be a very simple option, and Ashan was able to acquire some piping from the Chemical Engineering department (thanks guys!). He made a finger from it, but ultimately we also thought that this was a little too crude. Someone out there has made it look better though! :
However, as I seem to stress over and over again, we decided to go with the Thingiverse hand. It's currently still a little crude, as we didn't follow the recipe exactly, but it's good enough to play with!
