Re: Best Time Savings
I'm a mechanical stuff guy, and the best way I've found to save time is to think simple. Every year I see lots of teams invest a ton of time (we've been guilty too) into ideas or mechanics that were...

Re: Exhaust in Solenoids
Totally. That's why I mentioned it was not a good idea to use on the official robot, good for a quick test if you don't have any proper on hand. We purchase off-the-shelf rated plugs to use on the...

Re: Exhaust in Solenoids
These manifold blocks can be confusing to look at because the associated A and B ports are not right above each other, they're diagonal. I think they have it plumbed right (That part anyways)

Re: Macanum Drive Train Problem
It's asking a lot in my opinion to expect that they all output the exact same torques and speeds at a given current. We've run mechanum drives many times. In the past, we've used encoders, gyros and...

Re: How much air can be stored onboard?
Keep in mind that the more capacity you have, the longer it will take to re-charge when depleted. Sometimes it's better to have less storage that reaches full pressure faster.
