I presume those tubes are within your BUMPER PERIMETER.

I'm concerned about the offset in the frame, though. You've made the sides of the bot not on the BUMPER PERIMETER, so you have no legal method of attaching BUMPERS.

Just make sure you read the bumper rules very carefully before building the machine as pictured.

Great looking model!

But the side rails of the frame are not on the BUMPER PERIMETER. That makes it tough to comply with

Re: pic: DOC V: THE RING OF FIRE

In lieu of an orthgraphic to determine what is inside and what is outside of the bumper perimeter, I will assume that the bumper perimeter is formed by the four outer corners of the frame (the low part that the axles mount to) and that the entire robot fits within a vertical projection of this perimeter.

The rule violation as I see it from this drawing is a relatively minor one. The c-channel at the front and back extends beyond the outside rail. This means that you would either need to run a structural member to support the bumpers from one overhanging end of c-channel to another... or simply cut off the parts of the C-channel that go beyond the corner.

My guess is that you are planning to do this in real life, but it just hasn't shown up on the CAD drawings yet.

As far as other feedback goes, do you have a mechanism set up so that when you suck balls in that you don't end up with spaces between them as they climb the tower? If you are lifting them with just one belt have you considered that they will slow as they round the corner at the top end?

Re: pic: DOC V: THE RING OF FIRE

Heres a dumb question... will you have anything preventing the balls from going over the edge at the top until you want them to? like would you be able to collect your max capacity of 8 or so balls without dropping the top ones, then dump them all into a trailer? If you're able to do that, it may prove to be a very good strategy! good luck!

Re: pic: DOC V: THE RING OF FIRE

So the balls are pulled out by gravity? Conveyer to get it up there?

In this design, having any kind of launcher at the end of the bot is redundant since the pipes direct it at such a low angle.

Only problem is distance. Even at a height of 5 feet, you may be able to get a ball at max 3 - 5 feet. There is also the penalty of getting hooked onto your opponets trailer. I dont know if that was part of your stratgey but you defintately need to cut the pipes back in order to ensure that you will not get a penalty by accidentally hooking onto a trailer.

Re: pic: DOC V: THE RING OF FIRE

So let me get this straight: Each of those tubes will spew ignited propane at the opponent, melting them to regolith so you can score on them?

What? That's not what "Ring of Fire" means?

Oh.

Actually, I like the design, and the CAD skills are excellent. I wonder if the wheelbase is too short, in that it might affect stability in a collision by causing the robot to tip over forwards or backwards. That can be managed in other ways, but it gets tricky. Also, using the bumpers as part of the frame's structure is a good idea, especially if you use high-grade material (not regular sheathing grade). Our chassis has a roughly similar shape, and we had some problems with flexing (try lifting a front corent); be prepared to address this as well.

Very nice!

Re: pic: DOC V: THE RING OF FIRE

Are you making sure the cRIO case is electrically insulated from the chassis? It looks like you might be mounting it on metal.

That said, this is some beautiful CAD work and an interesting design. I hope it works well for you.

But that still means that you don't have that much range. So I'm guessing that your plan is to "corner" an opponet's trailer and dump as many balls as possible into the trailer. That means that whatever encourages the balls to leave ur bot must have the ability to get a lot of them out in a very short period of time. Which also means that whatever system that you are using to get the balls up to the top of the bot must be able to get them up at a very quick pace (cim with 4:1?). But thats just guesses.
