Cart Is Pit?

I JUST HAD A BRAIN FART!!!!! who saw the mythbusters episode with the hovercrafts? you think 6 leaf blowers would lift 600 pounds?

man that is a good idea lol....build one like adam's lilypad it would be quite stable lol

Didn't see that, but I saw team 1006's 2006 robot moving device: 1 leaf blower was enough to lift their robot at full weight. Need I say more? (Though you would have the directing problem, but that's what the other drive team members are for.)

Also, remember to put space for the operator interface. The OI is (can be) a very awkward piece of equipment, if it's long or in multiple pieces. It's easier to put it on the cart if possible.

And it's not just compressed air in those cans. They actually make me pretty woozy if I spray too much in an area that pretty much isn't outside.

Compressed air is good for blowing chips and junk out of the robot.

However, those little pancake air compressors (which are just about the only thing small enough that you could fit into a cart) will not run any air tools for more than a couple seconds before they lose so much pressure as to basically be ineffective.

"I had design this system to have the robot batteries being charged on the cart at all times even when your not near a Ac power source. To go along with that it provides a AC and DC lines for charging laptops and running some electrical tools depending on cart battery size and inverter being used."

I reference to the above information, be careful about doing this as we tried to do the same thing on a carrier that we built on year and we can to find out that the setup burned up three battery chargers running thru a AC to DC converter because the wave signal was different that the wave from the AC outlet. Just a thought from the past.

MrHance You have my Diagram slightly mistaken When it said "AC input" it meant only from a wall outlet. So the Three batteries would only charge from AC if it was present But when AC is not present then 3 relay would trip. One in the inverter so that the DC would be converter to AC and the two DC relays that would switch the batteries charging from the AC to DC converters to a DC to DC converter providing a nearly no energy loss system.

If you talking about inverters and their waves i have heard of these two "pure" and "synthetic" i currently own 3 (2 pure 1000 watt inverters, and one 400 synthetic). I plan to use the one of the pure ones since my DAD is a electrical engineer who told me too and for these parts came out of an ambulance so i hope they would be up to standards.

inverters companies
(pure)
Vanner (+ using this one)
Tripplite
(synthetic)

We did something like this and used it these past two years. Our cart had oversized pneumatic tires, places to charge 4 batteries, and a series of compartments for storing tools, cables, etc...

By no means did it replace the pit, but it was nice for transporting a compressor for charging our accumlators, as well as tether cables, programming cables, and of course a few zipties.

I don't know that I would recommend the chargers. I don't know if we ever used that capability once after the initial regional. Usually we just have our battery farm nested underneath our table in the pit so it's not that big of a deal.

The other hassle with using a multifunctional cart is that it is going to be much higher off the ground in most circumstances, due to the need for pnuematic tires so tools aren't flying around. We have had troubles in the past with 5' robots and getting them underneath doors.

We ended up having two carts this year. We used our multifunctional at Wisconsin and then we made a VERY simple cart using the kitbot frame and a few casters which we used at Toronto, Atlanta, and IRI. The simple cart was preferred for its easy maneuverability and overall, it was just easier to transport and ship with the robot.

I can see the practicality in building a pit-cart, but in my opinion as long as you're organized and plan ahead, it isn't really much of a benifit. It was nice at times to have the compressor or tether cables right there at times, but like I said, if you plan ahead, you won't really need it.

fog machines make fog from water. water plus electronics are bad.

True enough... but does it say anything about not having them??? cause our team has a plan for one,(it will be controlled, obviously, for the safety of other bots and our own).

Thanks for that by the way. I forgot about electronics lmao. I will have a chat with the designers about it.

Regarding all of this compressor hub-bub

The intent of the rule is so that teams don't fill tanks onboard the robot without having the nasson shutoff valve controlling the compressor. This makes total sense, even if the compressor is not onboard the robot.

Using a compressor for non-robot uses (such as blowing out dust and such) should be absolutley no problem, so long as that compressor isn't used to pump up tanks onboard the robot.

A good example of this is the duct tape rule. Just because you can't use duct tape on the robot, doesnt mean you can't use it on the cart.

My 2 cents,
Jacob

And nothing says that you can't have the robot's compressor on the cart, provided that you hook it into the system properly (legally) to fill the tanks between matches. Why have two when you can have one?

The KOP compressor would be all but useless for anything beyond charging the cylinders on your robot. I doubt you'd find it useful for even blowing chips off the robot.

[BlackShadowFox]

its not the KOP compressor that will be blowing but the stored air in the 24 in length, 6.5 in diameter steel air tank. This part was salvaged of the air horn system of an ambulance.

[BlackShadowFox]

Well now that we have talked a lot about air. Please post more ideas on the other fields if you could. I would like to see what others have been planning and also what ideas of mine could be improved.

That will work. But it'll probably take 20 minutes for the KOP compressor to charge that tank. I think you'd be better off with a second small industrial compressor to power your non-robot air needs.
