I've not logged in for a while, but I'm still working on my robot, as and when I get the chance. I'll update my robot page, when I have the next part finished. The next part is the reason for this post, however. I appear to have hit a stumbling block and as usual, I'm turning to the good folk here at LMR, for advice.
I've been working on a clutch mechanism, the idea behind it being, when my robot is moving, either in forward, or reverse, the 2 gearboxes lock together, with the afore mentioned clutch, which will then disengage, when turning. I've made the mechanism and it all works well, servo operated and functions in largely the same way, as a clutch on a manual transmission car.
The only problem I've encountered, is a material to make the actual clutch plates from. There are a few properties, I need from this material, so here I am asking if anyone can recommend anything. The properties I require are listed below.
1. High friction
2. Ability to be machined to size and shape
3. Easily available
4. Not costly
So, there we go. Any offers, anyone?
Thanks for reading,
Paul
