pic: 157 as of last week

This is the aztechs 157 robot so far. it is missing our grabber and other sections of the ramp.

Did you modify the AM shifter? It looks like you have a cantilevered shaft running timing belts to the wheels. What made you switch from chains?

We did modify the AMshifters to use timing belts. We have used them for the past 3 years becasue we were sick of the chains breaking.

How often did your chains break and how did they break?
You can send the info via your sister or come in person.

nice bot! it looks great! very nice base!
