Re: Team Eventorizon: Build Diary

that's not overly surprising on such a thin chassis

Re: Team Eventorizon: Build Diary

The problem of thin metal, and welding without continually checking for wonkiness

[Eventorizon]

Re: Team Eventorizon: Build Diary

On more detailed inspection it seems we have our problem. The main back plate at the base was welded a good 5 degrees away from where is should be and as a result that has moved all the other plates out of alignment. If we can get them to re do the back then everything should drop into place as it was designed to.

So, assuming you can simply grind off the welds to do it again...

Remove the 9 back plates by grinding them off then swap the two bent plates over so they are on the other side and as a result bowing out not in, adjust the angle of the central plate and re-weld.

Re: Team Eventorizon: Build Diary

Conker II is now beginning to look like a robot and not just a bunch of parts. Uprights are in and fitting nicely, motors are on and its got enough structure for me to be able to lay out the other parts in their final positions; see http://teameventorizon.imgur.com/all/.

There are also some comparison pictures of Conkers 1 & 2. Conker II is 80mm narrower than the original in its main structure but will actually be 100mm wider when the armour panels are on.

Binky has gone back to be re-welded free of charge but it doesn't solve the design flaw inherent in the design which is entirely down to me. The armour and base don't overlap and as a result the robot doesn't hug the ground like it should leaving it with a lip on all edges. We have several solutions for this but no idea which will work.

Re: Team Eventorizon: Build Diary

looks very impressive so far

Re: Team Eventorizon: Build Diary

I know the welds didn't work out but I'm not sure electrical tape is the alternate answer.......

So is Binky using the disc and bulk heads from Gary and you're making your own for Conker 2?

Looking good though!

Re: Team Eventorizon: Build Diary

I'm not 100% seeing the point in 2 spinner bots.
i think Gary's bulkheads are going in conker.
looks nice and snug

Re: Team Eventorizon: Build Diary

2 spinner bots = 2 spinner bots?
whats not to get

[archie2000]

Re: Team Eventorizon: Build Diary

no polycarb arena = 0 spinner bots

Re: Team Eventorizon: Build Diary

PJ-27: Yep, its Garys bulkheads and disc. So that will give you an idea of the type of machine it is meant to be.

When it comes to the armour, the gap was massive at the back, a good centimeter, so it needed redoing anyway. You could easily have got a spike or thin sheet of metal in that would take out the lipo's. When you pushed the back down the front came up by two inch's.

Conker II is built in virtually the same way as the original, but with some material changes and design tweaks. I have also raised the disc up so it doesn't catch on the ground like last time :-P

Archie2000: I thought that as well but given it was going to be my dads machine he got to make most of the choices. He didn't like the idea of a push bot like 540; thought it was dull, thought drum bots were not dangerous enough; I think that 540s replacement is going to make him change his mind. The list goes on. So we ended up with another spinner.

Conker has got the ability to take the disc out by removing 12 bolts, the idea being I could design a Biohazard style lifter to go in there instead or an axe or a crusher. So its not a one trick robot.

My only worry would be if we got drawn against eachnother at any point. Binky at full speed, in theory, can cut through hardox.

Re: Team Eventorizon: Build Diary

A new endeavor! As some of you may know, to push robotics and engineering in my university I started a robotics society.
We are currently building antweights for a internal competition and then perhaps having the chance of going against Reading uni and their antweights.

Here are the first parts of my ant; as yet unnamed.
[attachment=0:84bzdnac]20121026_193726.png[/attachment:84bzdnac]
Motors are 100:1 Mini Metal Gearmotors from Sparkfun with 42x19mm Pololu wheels.
ESC is a Sabertooth Dual 5A and the receiver is a Orange 6Ch RX.

I am going to have the chassis 3D printed at uni in ABS. We may have access to a titanium printer but it probably wouldn't be free and I am not sure if it would actually be as strong as the ABS.

Re: Team Eventorizon: Build Diary

Keeping with this threads maths theme, from my observations,
Sabertooth = smoke = fire.

[Max]

Re: Team Eventorizon: Build Diary

May I ask what you think the cost of your ant weight will be?

[Eventorizon]

Re: Team Eventorizon: Build Diary

Sabertooth =£49.90
Motors = £13.99 each
Wheels = £3.11 each
Receiver = £7 (2 for £13.99)
Battery ~ £3-6

Total ~ £90-100 excluding postage

The 3D printing will be free and I already own a transmitter.

And yes I have heard all about Sabertooth's = fire, I now own 3 and I've have no problems at all.

Re: Team Eventorizon: Build Diary

Same here, used them in all manners of robots from 3lbs downwards and never had a failiure, even with me taking terminal blocks off the boards.
