New Project Big Robot Thingy

[dgr]

So, a Die Gracefully Robotics heavyweight then. Some said it couldn't be done. Some said I was mad. Most....just laughed.
But said robot is now in production and this is where I will record whether the project is a success, or a huge failure.
Anyway, currently just finished collecting bits and pieces. Drive will be 2 wheelchair motors, 36v of battery power, Wotty speed controller and a chassis most saw being used as a cradle at Cabrakan's first event.
So, watch this space to see whether what will likely be the worst heavyweight in the world today will ever make it to an arena near you soon.

Re: New Project Big Robot Thingy

Well, its started. First pics are up, 2 different set-ups for the components. Not sure which layout to go for, both have advantages and disadvantages.

The first pic shows the wheels inside the chassis option. This protects the wheels, but also limits their size to being fairly tiny, and therefore making for a slower bot. It also requires more mouting work and precision, a quality that you all know I do not possess.

The second pic shows the wheels outside the chassis option. This is much simpler and easier to accomplish and also allows me to use huge wheels if I want, which will help with speed and weight. but it will mean they are unprotected.

Any thoughts?

Also, anyone have any tips on wheels? Should I get some made, or buy some ready made, or what?

Re: New Project Big Robot Thingy

would it be invertable with the tiny wheels inside?
If you look at alot of american robots alot of them have exposed wheels. They seem to do ok.

Re: New Project Big Robot Thingy

I'd have to do some measuring, but I'm not sure whether the tiny inner wheels would be big enough for running inverted. I think I prefare the outer wheel option, as its a lot simpler. I'll just make sure its too wide for Kan Opener! lol

Re: New Project Big Robot Thingy

Go with the wheels on the outsides. I did with Carnage These are the same wheels that TAN uses.

Re: New Project Big Robot Thingy

Are those wheels custom made Tony or can I buy them from somewhere?

Re: New Project Big Robot Thingy

Custom made By Mario I think. Had them donated for Carnage. Just a pity no where to use the robot.
They are the same ones that Tough as Nails uses.

With Wheelchair Motors

Re: New Project Big Robot Thingy

Right, big lack of updates but the project is progressing smoothly. The robot is no longer running on wheelchair motors and no longer looks anything like the above pictures as I am no longer using that chassis (not in the way its pictured anyway).
Without giving too much away, the motors and batteries are mounted (apart from some extra long bolts for the batteries cover), next job is to get the wheels on and the wotty in place, and to build it up from there.
Providing the wheel mounting goes well (it's a little problematic) then it should be a smooth enough ride. Without drawbacks, I will be ready to debut at Wigan. With drawbacks, start of 2010 events. I am out of a job again so unfortunately I can't just throw money at it to get it finished anymore.
Anyway, not the most interesting of updates. These things get more interesting as the project progresses obviously, so watch this space, should be something kicking around soon.

Re: New Project Big Robot Thingy

OK, first few images now its looking a bit more robot-like.

This is it with no armour, and the wheels arent attached properly, they are just on to give an impression of how its going to look.

Excellent big-wheeled robots this is the future no more tin plated snails getting stuck on an atom sticking up from the floor!
Robots bundling up like a banger racing smash lots of action rather than the lumbering molluscan gastropoda struggling to move across a piece of MDF they are so boring!

Re: New Project Big Robot Thingy

I wholeheartedly agree Craig!

Re: New Project Big Robot Thingy

Dave, just as a side-note and something I've always wondered? Is there meant to be a 'y' missing in your signature, where it currently just reads 'Gracefull' ?
(random question I know )

Good luck with the new build, looks to be coming along nicely so far

Re: New Project Big Robot Thingy

Yes Jamie, there is supposed to be a Y there. lol. I'll change that methinks.

Re: New Project Big Robot Thingy

Yes, I know, I've barely updated this at all, but I've been dead busy. Anyway, robot is now pretty much 100% different from all that this post has previously said, as happens with so many of my projects. However, it is getting very close to being ready, fingers crossed.
There aren't that many pics around, kind of want to wait til it's finished, but here's a recent just to keep you all happy.
