I like it, looks simple and reliable. Someone will need to be the first leg of every alliance. Could you post some brief robot functions? I'm assuming it can score in the low goal if need be but can it pick up off of the ground? How is its catching ability?

Nice render by the way, looks classy.

Thanks! Simple is what we were going for. Some ideas/functions:

Autonomous: Drive to low goal, deposit the ball, reverse to starting position (for better field position).

Teleop: The idea is to be easily fed from the human player and not have to pickup from the floor. If necessary, we can do floor pickup, but we'd have to trap the ball first. If we're doing our job, this shouldn't happen. The orthogonal wheel configuration allows us to move the ball in all directions when on the robot. It's not completely assembled so we haven't tried catching yet, but hopefully when the up/down wheels are spinning, it should make catching easier. We'll see...

It's a 4 CIM kitbot but we geared down to 10.71:1. We might swap out the tough boxes for 3CIM4U's.

Questions, comments, and criticisms are welcome! Tell me something I haven't thought of yet!

If your plan is to be on the first leg, then strategically you may think about building a high goal blocker. You look like you have room/weight for it and it would make you incredibly desirable.

We thought about a high goal blocker but couldn't figure out how build one that would collapse to maintain our low CG and wouldn't deflect outside the 6" column while deployed when hit with a ball. We thought double scissor lift would work maybe. If you have any ideas, I'd appreciate it. We thought I'd be too easy to counter in teleop, so it would only be effective in autonomous. Maybe it would work if you placed the bot in the middle of the goalie zone and used the slider on the driver station I/O to tell the robot how far left or right to move to be in the way of a shooter. Anyway, just a thought.

have a 4-5" tube stick up to about 5' (max height). have another tube slide inside that which is a good fit (you could use small platic plates to make sure it slides nicely and use a pully system to deploy it to however high you want... (you can learn from the pink team)

If you'd like to pursue this further feel free to ask any questions!

Yes, Your type of robot will be very useful. Our team will be look for robots like yours.

If you have the weight to play with, you may want to have your back wall be 60" tall to block all the low to the ground shooters.

Good idea. Might as well add some lightweight height to it. Maybe to assist with catching/loading. Pool noodles may make an appearance...

[AllenGregoryIV]

I'm definitely hoping at least a few teams build robots like this at the regionals we attend. A dedicated inbounder will be really useful to a variety of alliances. Even if you're not tall you may still be able to play effective defense if you are smart about it.

While you are at it, make a 20" extension that swings up around a pivot right at the 59"-60" mark. That way you are even more of a nuisance to any shooter while nearby.

I like the artwork! We're not sure how high we would go with a blocker but this seems like a good idea at any height. I'm a little unclear on the rules on shooting. Can the ball be shot from any zone?

A robot shooting into their goal must be between that goal and the truss

(so no full court scoring) but Half-court scoring is legal
