I’ve been working on my robotics project for the RoboCup Secondary for quite a while now, and one problem I have been running into is a constant and rather annoying lack of traction.
The robot, picture attached, uses two 2cm-wide belts printed out of NinjaFlex.
Although this is enough for most obstacles, the contest also features 25° incline slopes, which pose quite a problem. Additionally, the ground of the contest area is a pretty flat and smooth, so it is rather hard to get a grip good enough to climb these inclines.
I’ve already tried a couple of things, from anti-slip varnish and PlastiDip, to coating it with silicone from the hardware store.
Silicone has proven itself to work quite well, however with the downside of very quickly rubbing off, and actually having too much traction to work reliably. The varnish and PlastiDip however do not provide quite enough, and also slowly wear off (although the wear is tolerable, as the coatings only need to persist throughout the 1-week contest time).
So I want to ask you guys!
What do you think could I try too? Is there any way to make the silicone coating more persistent, in your opinion? Or do you know of some other way that will give the belts more grip?
The contest is in one week, so any quick answers would be greatly appreciated!
