In Need of Banebot Wheels

We tried the adhesive backed versions on manipulators in the past but even after giving it plenty of time to cure it did not want to stay on while under load. We tried using a couple of fastening methods as well but it would usually end up tearing out when under load. This was using strips that where 1 inch wide and with a thickness of 3/8ths of an inch. How wide were your strips and how did you fasten them? How often? Any issues with it tearing out?

About what rpm were you spinning at?

5254 used colsons for their collectors the entire year, and with the modifications made for IRI copying 1114's collector geometry, they were extremely effective at intaking totes at near any angle.

I'm a firm believer that most of the time the small improvements you make in material choice to solve problems might be better solved much of the time by a geometry change. Incrementally improving a middling design can be good, but often scrapping the middling design and taking a different approach can often be more effective.

1592 completely agrees. But material choices is the next thing down the line on a list of things that can improve the functionality and use life of subsystems on your robot.

Any chance you have the part number of the specific type of polyurethane strip you used.

I believe it's on McMaster as Soborothane (or I'm getting confused with a different part of an 1114 robot)

We over sized the diameter of our hubs by about %10. We had no issues with slipping or installation.

Here is a pic of our wheels if anyone is interested https://scontent-lga1-1.xx.fbcdn.net/hphotos-xpa1/t31.0-8/10256793_10155208355065576_3280327124933048631_o.j pg
Urethane is 30A and the hub is resin cast.
