robot

[Laser]

Hi again guys. After a long think im going to buid a antweight to get into robotics then hopefully near christmas i'll start building a featherweight. I've looked at pneumatics for a flipper and thought it was too much and too complicated for a first bot, so im gonna build a ram bot (measuring 40cmX30cmX15cm) with a ramp on the front.
the frame is gonna be made out of wood and the amour is going to be 6mm nylon 6.
for speedos I dont know what to get out of the electronize FR15HVR or the sabertoothdual 25a which is better
I'm using 12v cordless drill motors(already been ruining my dads old drills He He..).
Ill use my Spektrum DX5e for my ant and subscribe to RCM&E (im into RC Planes) and get a free Planet 5 transmiter then buy the reciever for my FW.
Icould go cheap and buy these wheels http://cgi.ebay.co.uk/ws/eBayISAPI.dll? ... K:MEWAX:IT
or buy 2 blue wheels with nut insert and 2 ball bearings.

Thanks

those wheels http://cgi.ebay.co.uk/ws/eBayISAPI.dll? ... K:MEWAX:IT won't fit on to drill motors directly but the Robo Challenge €˜Blue wheels€™ with nut insert. will. http://web.me.com/robochallenge/Robo_Ch ... nical.html (3rd down)
the ebay wheels are cheep so you could buy them and use them for something else.

sorry the design is for the featherwieght

yes I Just read that

If you're building a simple pusher with 2 or 4 drills you will have loads of weight left over with wood and 6mm nylon armour - not to mention that if you're thinking of entering an event which has spinners running, 6mm of nylon will put up about as much resistance to a heavy spinning blade as a bunch of slightly damp tissue paper.

In other words, get yourself thick plates of a decent aluminium alloy (15mm+ of a 7000 series will do), or some hardox or a similar toughened alloy steel. There are plenty of people on here with some knocking about.

i wont be entering events with spinners and i could put aliminum on the outside of the armour as reinforcement.

I would have it less than 100mm tall so you can use 100mm blue wheels so they stick out the top and bottom so you can drive up side down

that is a good idea alex and i have thought about what happened if i got flipped ands talked to my dad about it i could make 90mm high but at that kind of hight the ramp wont have enough angle to make robots go airborne.

[Bodge Job]

you could shorten the ramp

that would work
