Re: Massacre - FW

Nice design...looks really menacing. And if well built its capable of inflicting quite some heavy damage.
A local team has a similar machine (pic below)





and it did do quite a good deal of damage!!

Your design reminds me of Hazard

I doubt it will be anything special, but it might knock a couple of hdpe robots about.
Update, had lots of spares and other bits arrive including the battery, an 18.5v 4000mah 35c lipo. slightly wary of it atm, I need to order a slightly bigger lipo bag before I attempt to charge it, hope I don't break anything on the first charge

EDIT: just found a bit of stainless steel bar which is almost exactly the right size, i'm just worryed its a tad thin at 10mm? what do you people recon?

I think its not the thickness which matters in your case, but the width of the bar, and also any holes drilled in the bar will weaken it, for example on Pacman, the bar they used measured roughly 500mm long, 3/8 thick and 2 wide made from steel - it got bent from the centre because the mounting hole was too big.

Out of curiosity, how are you going to transmit drive to the spinner?

Re: Massacre - FW

Aye, I was worried about breaking or bending at the center, so I am supporting it slightly by putting it in some hdpe.


The speed 900's run through a right angled gearbox which then has another stage on it. This is probably not the best or even a sensible way to do it but it might work okayish for a fight or two.

Re: Massacre - FW

I'm afraid HDPE wont help that much, it too soft I think :| but than again, it depends on the hole you put in the centre - you could try to keep it as small as practically possible...
Does the gearbox connect directly to the spinner bar, or you got some type of clutch/bearing there?

Re: Massacre - FW

HDPE is no use as a structural support for metal. It's to flexible.

Re: Massacre - FW

noted. thank you.

Had the armor and bits for the frame arrive, so have now managed to get it into drive-able state. took some videos.

Re: Massacre - FW

May just be the way your camera picks up sound, but your drive motors sound quite...crunchy. The same sort of crunch you hear in adverts for Crunchy Nut Corn Flakes. Are they decently greased up?

Otherwise it's looking good! Nice solid machine.

Re: Massacre - FW

They are rather crunchy. I desperately need to re grease them. Luckily this is an easy robot to take apart. But thanks anyway mate
