Re: IFI Traction Wheels V2 Testing Results

It is in my experience with these wheels that many of the more pressing issues took place with the larger diameter wheels. I had witnessed many of smaller thicker diameter wheels going through competition unharmed.

However use of the larger wheels such as 8"x1" wheels were not able to hold up. Keeping the wheels concentric ( mainly due to the retainer which has apparently changed ) and if the wheels experienced any side loading from robot impact or field element nasty things seemed to happen.

One of our main problems is that as the tabs bent inward due to stressing levers as you claim our plates began to bend outward. Using our large diameter sprocket that we had used catastrophic failure accured in such a manor that half of plate peeled away from the wheel. Before the match the screws had been tightened and tho the tabs weren't in perfect condition but not terrible, it seemed as the screw had literally been ripped from the wheels.

Sounds like you are making changes to this so thats good. My question is tho look at your chasis and your initial support where the wheels tested under full load? It doesn't seem that your chasis is the typical weight of a robot. Just a curiousity, was weight added before conducting your testing.

Also where the wheels put any side loading such that it would emulate impact from a robot? Our wheels performed perfect when in straight lines, its when we were hit or turned did problems occur. ( Mainly the hitting part )

Also will testing occur on the larger diameter wheels?

I enjoy the benefits of the wheels i.e. Size options, ease of assembly and use in application, weight ratio, but still concerned as the structural integrity. Maybe not of the smaller wheels, but of some of the larger wheels.
