Re: FRC 95, The Grasshoppers, Build Thread
An end-of-build update.
We bagged a nominally functional robot. All of our features work, except for vision tracking (due to inadequate LED illumination, mostly).

Re: #25 Chain
The recommended working load of #25HD is around 90lbf. This is fine to exceed for shorter lifespans, but with the tiny sprockets teams are running this year... :eek:

Re: Withholding Allowance
I was really peeved when I first read that a team had brought two robots (note the un-capitalized usage). But then I read through this thread and arrived at the conclusion that what the Zebracorns...

Re: Is Defense Back in a Big (Bad) Way?
I am interested to see how the lack of 'tall' robots impacts defensive play this year. It strikes me that a box with a stick or a box with a wall will be a very effective non-chassis-contacting...
