Antabuse (aka DieSulfiram)

[JamesDavies]

Making an Antweight for the next AWS. Got all the parts working together. Need to get materials and build a body now. Will most likely go for a dull 4wd pushing box for the first one just so I can get something which works. At the moment the wheels are bottle tops with rubber bands around them. Is this a terrible idea? It seems to work fine on my desk...

Thinking of either HDPE or polycarb for the protection- any thoughts?

Will update when things happen.

the milk bottle tops will suffice providing they're held onto the motors well.

Also, be careful with those batteries, the tabs underneath those black caps are a bit flimsy.

[JamesDavies]

Great, they seem okay. How would you suggest holding them on? At the moment I'm just drilling holes slightly too small and squeezing them onto the shaft.

How do you mean? Which tabs are they? I'm having trouble charging them at the moment. None of the 4 seems to be taking charge...

[razerdave]

I seriously hope you're using the correct kind of charger...

I use these cells for 3 (used to be 4) of my ants and I take that black casing off and the connector so I am left with 2 bare tabs so I can hard wire the 2 cells together into the robot. Saves me the weight of the caps and any extra connectors.

[razerdave]

Oh, and as for the wheels, that hole won't hold for long. Did it like that on St. Jimmy and it rounded out the holes after a few fights. Not sure the best way to attach them to milk bottle tops

[psychostorm]

I thought milk bottle tops were made out of foil?

[JamesDavies]

This is the charger I am using...

Ah I see... For now at least I'll be leaving the black tabs on but thanks for letting me know
Okay, I may just bring several sets so I can replace them when they get rounded out :L

What armour would people suggest for a rambot? Currently weighs about 100g. I was thinking 6mm polycarb or HDPE. Any ideas? Also, where is the best palce to source this? Thanks.

[razerdave]

6mm polycarb is good armour for a rambot. I use it for Bulletproof and its taken the worst the spinners can throw at it.

BTW, that charger should be fine for lipos, can't see why there's a problem.

[JamesDavies]

Great-thanks. Do you buy it online? Or locally?
Okay, will try poking around with the charger...

or ebay

Great thanks

[JamesDavies]

Put some HDPE over antabuse. I think I overdid it a bit going for 6mm as it's not 200g :/ 100g for the armour and 100g for the innards. Thinking of going down to 3.. which *should* bring me down to exactly 150g.

I'm not surprised that's 200g It's not standard practice to make all your robot from the same thickness material. Try and build a robot with sides. Have 6mm side peices and then you can screw thinner panels to it. Also, maybes try for a wedge?

[JamesDavies]

No, I now realise that I was planning to put thinner material on the sides but with the wheels external to it. Is that sensible? Or not? Would 3mm HDPE be appropriate? I am also planning a wedge but it was starting to look like it might not fit into the cube (and the weight was shooting up and up) so I just made it as a box for now.
