Rhino tread snapping?

We hope that it's just due to the fact that it was a heavily used track that has a lot of wear during build season and post build season.

We at AndyMark have not heard of anyone else breaking a tread. These treads are rated at 600 pounds of break strength, with a safety factor of at least 2. The white (or clear) colored timing belts are reinforced with a continuous loop of steel cables.

Can you provide more information regarding how your tread broke?

Will do! Honestly, I still haven't heard the full details (it broke late last night, I wasn't there), but I expect to get the entire story (as well as a picture of the treads) today when I go in. My preliminary understanding is just that we went into a head on bumper to bumper collision with another robot, and in that collision we heard a snap. The carpet ripped underneath the robot - we aren't sure if that was due to the force of the tracks snapping or perhaps a symptom of the same issue that broke the tracks (maybe something sharp?). Our drivetrain uses 2 CIMs/side, but I don't remember the gearing (it's nothing crazy though).

However, that is comforting that they are rated for 600lbs - makes it sound more like a freak accident than anything!

Thanks for the support!

I too would like to see a photo of this snapped belt.

We had no issues with our treads they were flawless deep into back to back regionals....so that's 28 matches plus several practice matches.

We did have to replace all revision 3 with revision 4 pulleys

Just curious if you HAD TO change all to rev 4 or you chose to change them to rev 4... in other words, did all of them break?

We went into competition with revision 3 (not my call I wanted then all changed out prior only had 4 and we ordered 8 more) and yes we ended up breaking all of them and replaced as we went with rev 4

What is this Rev 4 and 3?

Rev 3 is referring to the pulleys which shipped with the Rhino originally. Rev 4 is referring to the new pulleys that were designed to eliminate the failures that some teams were seeing with rev 3.
