Is the perimeter of this thing really under 112 inches? It looks huge!

Our perimeter measures out at 110".

The VersaWheels do funny things to the perspective.

We coded our robot in Java using the Command-based template.

Within each subsystem that used a Jaguar, we ensured that whenever we caught a CANTimeOutException, we called a subsystem-specific recovery method to re-initialize and verify the configurations of all Jags within that subsystem.

This ended up being a bit tricky for some sub-systems, as we switched Jaguar configurations depending on the task we were doing. i.e. the drivetrain could be in VBus, Position, or Speed mode at different times in the match. We had to keep track of these states, and restore them gracefully.

We had to handle the deadlock condition as well, because sometimes the error recovery would cause more CANTimeoutExceptions if the affected Jag wasn't ready to be re-initialized. Gracefully handling this condition without stopping your entire CAN communications bus was a bit tricky.

At worst we only wanted a single sub-system to "pause" just long enough to gracefully re-initialize the Jaguars after an exception. All the other sub-systems had to keep going as if nothing happened.

Interesting, maybe I'll have to chat with you guys in more depth post season about this. We use Iterative and C++ so your approach wouldn't work for us.

This is especially true with 256's drivetrain.

I agree with you here. With the lack of safe zones, teams that decide not to pursue shooting will have a very good opportunity to be a defense bot.

I disagree. There is one rather large safe zone of each side of the field(the pyramid)

While I agree with you that those are two major protected zones, this field can be considered more open because there is nothing in the middle of the field. I have a feeling that lots of teams will have to traverse the field to the feeding station, so defense in the middle of the field may be at a premium. I'd be interested to see a list of percentages on how much of each game's field is taken up by field elements or protected areas.

How do the horizontal tubes attach to your side plates? I see a bolt coming out but can't tell what that is anchored in.

We put three roll pins through the side plates that fit into the inside corners of the horizontal tubes. The fourth corner is used for a threaded rod to tie everything together. We started using this construction a few years ago, and it has served us well.

So the threaded rod crosses the entire chassis?

Yes! You can see it through the holes in the square tubes at the back of the robot.
Use one of the two bottom holes for the threaded rod. Gravity and the inside corner of the square tube will help everything line up. The oval cutouts aren't just to save weight, but also provide access into the tube to help align the threaded rod when assembling/disassembling.

This square tube + plate + roll pins + threaded rod assembly is one of my favourite "little-things" that our Design and Manufacturing sub-teams do.
