antweight first attempts

23/09/2000 Well the SMA axe is proving to be very difficult. In theory the flexinol requires 400mA, and gives a contraction of about 5%, the problem is fixing the ends, soldering de-natures the wires abilities and clamping is a nightmare. 
So we're looking at another servo to power a rear flipper/ax/SREMECH, though the liitle guy runs upside down fine. We've got plenty of weight left, as we're only upto 104g so far.
The wheels are now sporting rubber bands for improved grip too.
Adam and his friend Duncan have been practicing driving the little guy , so hopefully he will be team captain for the Antweight wars in October. 
I can smell victory.


History:

A 4.8v NiMh PCB mount battery provides the juice and at present were working on a shape memory alloy powered axe, which weighs almost nothing, but we keep frying the wire, so for simplicity we may just bung another servo in there.
Chassis is now made from an old Rotring pen case, with packing foam armour

First outing should be the world championships at Guilford on October 29th 2000

robot rebuilds

For two years in a row I've missed out joining in with Ian Watts robot bash at the Uni. So I'm making sure I've got something running before it swings around again. So I welded a couple of new gearbox cages into the 4 wheel push bot, and dug out a set of Electronize speed controllers. I fitted the titanium plate that has been cluttering the basement for a decade and have been doing some testing with a set of LiON batteries that used to belong to a cordless strimmer, which fell apart from overuse. I've run it up and the battery doesn't really have enough life to power 4 motors, but is useful for testing. I've stuck some old NiMH units on a charge cycle to see if they have enough life for a bout or two. The only things I actually need to "buy" are a 2.4GHz radio set, as the old 40MHz stuff is against the rules these days, so I've ordered a Hobby King 4 channel set for £20 off ebay. Strangely yesterday Mentorn emailed a bunch of robot folk to

Fake Plastic Trees...

So, for a bit of light relief I bought a few of Justin's LED Christmas tree kits. I think the original idea was to have a relatively easy kit to put together on Saturday workshops in the run up to Christmas, but they seem to have become quite popular with all manner of folk. Anyway, the kit is based around a couple of well made pcbs, a bag full of components, and the simple instruction that +ve is UP. It took about 10 mins to solder all the bits together, and with a huge amount of satisfaction over the end result. Justin and his Christmas tree kits can be found here: http://cyber-lane.com/ The Build Brighton Christmas workshops will be running each Saturday from 30th November to 21st December from 10am – 2pm. Entrance is completely free. Kits are priced between £2 and £5. #BuildBrighton can be found here: http://www.buildbrighton.com/blog/

The weakness of machines

All of the robots I have built have failed in fights, and usually at the axles/wheels, it's like a running joke. So why should it be any different with this featherweight? Meathammer was designed back in 2005/06 when using 4 drill motors was a bit of a novelty... it was made more novel still by mounting the epicyclic gear cages directly to the chassis, which unfortunately sends all the drive shocks back through the gearbox. The original version ran for a number of fights at modelworld 2006? and even won some, especially the sumo, which favoured its very low profile. I've just rebuilt the gearboxes with all metal gears, and tested it, and it seems it should last for at least one fight… but as I put it in the car after testing, I noted one of the wheels had nearly fallen off. Mark that bolt for Lockthreading! All this got me thinking if I could make something less likely to lose a wheel, break a gearbox etc I have a huge pile of bits and bobs that were destined for heavie
