Thetopcat's build log

Post by thetopcat84 » Wed Aug 29, 2012 8:00 pm

Thought it best to start my own thread for this, but planning on putting together a couple of fleaweights to find my feet in combat robots...

So after getting the final bits through today, I threw a few things together and got something working!

In case you're wondering, the thing that flies off was the unsecured battery...

Congratulations! You have made it to the best stage of robot combat - having something that works for the first time! :D

And its looking like it could end up as something pretty cool too. Is it built to go in the 3" cube? Are you planning on attending the FWS/AWS? Looking forward to seeing it in an arena soon!

Thanks guys!

Haz: I've got it setup on a single analogue stick with each axis controlling a wheel (so to go straight forward, you push up and left)... it doesn't really like going in a straight line, but it does like to spin!

Dave26: it's far from competitive, this was more a sort of proof of concept for me, throwing together a drive system and taping it to a piece of plastic. From humble beginnings and all that!

Think the next step is to assemble something like a flipper fleaweight, but the longer-term goal would definitely be to rub shoulders with you guys at a F/AWS! :)

All I do with all my robots is tape components to a chasis and I'm very competitive! lol

Haha, well then maybe I should take a leap! Any particular tape that's spinner-proof?

I've linked in a servo on the throttle stick for a flipper now, so the internals are all there (though a switch and charge link would be nice). Just need to assemble a chassis and body.

Question: using towerpro sg90s, is it normal to be almost constantly adjusting the trim? Might be the transmitter (e-flite MLP4DSM). It's just a minor irritation.

Standard duct tape used properly is very spinner proof. I've had many compliments of how mine hold up. Normal cellotape is a bit weak nowadays though. See Zenith vs 747 on YouTube for proof of that. Lol

Gotta love duct tape... Ever see the Mythbusters episodes? They made a boat out of duct tape!

Anyway, today I have mostly been cutting down on wiring:

Need to order up some 1 & 2mm hdpe and a switch next...
