Re: pic: Swerve drive in a Power Cube

Electrical teams hate him!

Major props for this design. I thought about this all season after teams built robots in totes in 2015, so I'm really happy you did it.

How high is the center of gravity? With the battery and motors that high up, I'd be worried about it popping wheelies and tipping over.

Also, why CIMs instead of MiniCIMs? That change could drop the weight and lower the center of gravity.

Re: pic: Swerve drive in a Power Cube

The only way this could be better is if you were able to fit the entire robot inside the milk crate itself. With the handles, it would make for a great carrying case.

Very cool design and packaging. One question: what's up with those vertical spur gears?

Those are the steering encoder gears. Check out the original module post, which I will note that you posted in .

So when this is playing Power Up on the field, other robots will be able to intake it, and climb... earning a double lift!

Re: pic: Swerve drive in a Power Cube

Build one and put it on the field for an off-season event.

Let's see just HOW good that vision tracking autonomous routine is, eh?

Thought it looked vaguely familiar... all these swerve posts blend together

Re: pic: Swerve drive in a Power Cube

New idea for IRI:

Each alliance has a power cube bot that starts in their opponent's cube pyramid (middle of the base 3 cubes). Playing the Lv3 Force power up activates your alliance's cube bot, which one of your technicians can control from their seat. Robots cannot manipulate this cube bot.

The idea is to be annoying as possible. You can herd cubes, but because of the small size you won't be able to push multiple cubes.

Inventor says it is a bit above the cent of the cube after assigning everything the proper weight values.

I chose CIM because I wanted to have the most POWER. Mini Cims would help to lower COG but not that much as the cube weighs 40-60lbs.

As nickbrickmaster sayed it is to get a 1:1 steering with the absolute encoder.

Quote:

I'm not sure if lifts and intakes can safely hold 40-60lb cubes.

Quote:

Oh no the lift is broken, it's not lifting the cube.

That would be fun but running cost of this robot it would be expensive. Maybe if you use FTC electronics.


Thanks for all the responses.

Re: pic: Swerve drive in a Power Cube

What's the ground clearance? Think you could get it up to 3/4"? With a robot that light, 775's on the drive should be 100% fine.

Re: pic: Swerve drive in a Power Cube

This thing has an absurd power-to-weight ratio!

I would be worried that it could launch itself. (G09)

The ROBOT implementation must obviously follow a design approach intended to play FIRST POWER UP (e.g. a box of unassembled parts placed on the FIELD, or a ROBOT designed to play a different game, does not satisfy this definition).
With the addition of securely mounted bumpers, this robot is capable of the basic needs, and can do several POWER UP↗ functions, most notably pushing a cube into the exchange or to set up an alliance partner, and possibly being able to participate in a buddy climb with robots not really designed for a buddy climb. There's certainly no reason to think this was designed to play a previous game (though it might have worked well for several games, most notably 2008 FIRST Overdrive, in a Team 148 Tumbleweed like role).

If you put a yellow power cube cover on it (presumably with holes for the wheels), it would likely run afoul of H07 (emphasis mine).

The nice thing is that, to climb, another team can jut put the robot on their cube lifter.
