plenty of stuff done on woodzilla. firstly the layout has changed a fair bit.
originally twas going to use a 24v pack in there, but 24v is alot of power for such a fragile bot so i think its a safe bet i wont be using that saw.. its robbing parts from kang and ill have to buy a new motor = pfshhh (me buy something )
so i took my spare 12v 2.4ah nicad packs and shoved that in, instead. plenty of space saved and weight lost, and i can use 9.6v motors which i have about 7 of at the moment compared to the 0 12v ones i have. the battery bay has now changed its shape and the relays pack in right next to the battery. all 4 of them at the moment.
another thing ive done is reversed the robots orientation.. i thought it looked really spastic with the big chunky part of the robot as the front so now the wheel end is the front and the chunky ass is the rear.. looks far better IMHO. gives it more of an aggressive look. reminds me of scarifier that way too.
and ive started to look at the control system finally. innovation is always a good thing so im very keen to use the IR controllers. there voltage is about 4.5v standard so i had a 4.8v pack in there to power things, but that wouldnt give enough voltage to set off the relays so ive replaced that with a 7.2v flat pack, which surprisingly sets off the relays reliably. i let one sit for a half hour and it didnt click off, and i shook it around too and didnt have it click on and off.
all the controllers and its battery pack is stored in one of cobras old red battery boxes. it fits all together well. the battery sits flat on the bottom and then theres abit of foam around it, then the controllers are above that encased in even more foam. the box is bolted down internally with 4x m4s.
the drill actuator andrew gave us shall definitely get used somewhere in this contraption, itd be rude to not use something that cool.. at the moment its making some really bad noises, i think a gear inside it is stripped out so ill take that apart soon. thinking of something like a scarifier lifter with a few hackifications... something about that one drill mech i really like.
was pondering a pnuematic version too, and a couple of drunk hobos in the city gave us an idea.. using a goon bag valve as a poppet somehow, dont know how much pressure theyll take but they look about right. _________________ www.demon50s.com - Minimoto parts
