I'm still not sure on that as I'm still trying to find my material costs. I'm on the last test as it were so I'll probably have figures tomorrow.
I had a new batch waiting for me when I got home which was easy to demould and holds onto the tyre well, I'm still going to test the stretch tyre method as I think it would be lighter. I managed to do some nice tests on the new wheels today and here are the results using Stanley as a test base since without acetate 100% of the robots weight sits on the wheels making it a good control. All setups were Stanley pushing into scales with my mousemat as a control surface (it's fairly smooth but textured enough to work and most importantly consistent). I made sure Stanley weighed 150g in each test.
Single pololu: 170g
Double pololu: 186g
Single moulded:267g
Double moulded:306g
As you can see the moulded wheels see a 60% increase in traction!
I also had a load of fights with Stanley versus Bullydozer, normally two very evenly matched robots but the moulded tyres heavily tipped the scales putting down enough power to ram bullydozer against a wall and over. All in all i think it was a great success!
I'll finish my last round of tests and get back to you on pricing.
