[BW] GR-01 Build Diary

[Giles]

Could you elaborate on what you mean with the arms preventing each other from moving? Each arm can rotate freely regardless of the position of the other arms. Unless I've overseen something?

You are completely right about the bending though. Unfortunately I think I'm just going to have to live with it and bring plenty of spares as you said!

[Niels - Team K.a.L.M.]

The arms look like they touch each other at a 90 degree angle, which can lock up due to gravity.
When tilted slowly this might pose little problem, yet when flung due to an opponent this could do you in.
I might be wrong and your cad design is sound. but I can't help guestimating how it would react to the effects within the arena.

Anyone else willing to weigh in on this one?

Edit, try animating it when flung sideways...

[SamO]

I think the GIF makes it look like the prongs have the same horizontal position on shaft, where as in actual fact i think they're just next to one another- you can see this if you slow the GIF down. That probably doesn't make much sense but I think Giles can probably explain further.

In short, it looks fine from where I'm sitting

[Giles]

That's absolutely correct, yes. They sit side-by-side, using the axle of the neighbouring arm as a stopper, preventing it from going too far into the wheel housings when not in use. (I've yet to model the axles in here):

You'll be fine than.

Brb whilst I just whip up a sweet 3D gif of my robot for the hell of it.

Awesome stuff man!

[Giles]

CAD files sent off to LaserMaster for cutting! Look forward to putting some bits together at last!

[Giles]

Laser cut stuff arrived today. Its starting to shape up nicely! The side armor is a little on the heavy side, might have to do some weight reduction on those or replace them with HDPE if that fails. I've gotta drill out all of the 5mm holes as for some reason they are way off and do not fit the 5mm bolts. 4mm ones are fine though. Can't wait to get this all assembled now. Need to file off all the burrs first

looking very neat

[suvv]

thats looking awesome...heavy......but awesome

[Giles]

No update in a while! Been busy working on my feather. I finally printed some nylon spaces for the chassis and cut some threaded bars to size. I also had to redrill some holes as they needed to be slightly wider. Heres a chassis semi assembled:

looks awsome whats it weighing in at

[Eventorizon]

A thought about those front forks. When the bot is upside down the weapon will, in effect, be spinning downwards, so if it hits something it will end up trapping whatever it hits between the forks and the weapon will stop. While this probably not going to break the weapon, it may well bend the forks and it will give the weapon motor and belt a massive shock. Given my new version of Conker is very similar I have been thinking about this a lot, and I believe you only need forks on one side so you can use the weapon to self right on the arena wall/opponent when the wrong way up.

[overkill]

Wouldn't the articulated forks just move out of the way as the bot flips itself over? And does this mean that Conker now has articulated forks?

[Eventorizon]

If he can't hit anything because the forks are sticking out, he cant turn himself back over. Also, if they can swing out the way then there is the potential to get beached on your own forks.
And no, Conker doesn't have forks.
