|13/2/01- Still waiting for the gears.... so no wheels yet
|Revised Specifications for Killer Carrot
||Mig welded 35x15mm 2mm box ERW steel, forming a 400x400x200
cross-braced perimeter frame.
||2 x 24v surplus hi torque (weedy) motors from display
electronics. (Don't buy these, save your cash and buy something
decent from Roger Plant)
||2 x 4QD NCC35-24 through a DCI, pots linked to 2 Futaba
||Futaba Skysport T6YFK, 6 Channel Tx, 40MHz fm,
FP-R138DF 8 channel dual conversion receiver, with 1 RF-1 failsafe.
||Middleweight, under 50kg
||Motorcycle sprockets and chains 8.2:1 reduction on
new 10" pneumatic tyres, giving around 8.5mph top speed
||2 Micro kiel 18AH 12v's
||40mm pneumatic ram giving around 60kg's of lift via
a pivoted arm, rear mounted spikes for ramming.
||3mm BASF RESART polycarbonate
Can run upside down.
||So here we have the smashing new chassis with new crossmembers,
clad in an attractive BASF LESART, that's polycarb to you and me.
You can see the "snout" on which the flipper will rest.
This is head on with the new paint job... strangely enough we've
gone for fluorescent orange again. The paint is applied to the reverse
side of the polycarb so it can't be scratched off, but it does mean
I had to paint back to front, which was weird
||And here's the top panel, the slot on the top is for the flipper.
The ball transfer unit is at the back giving us "upsidedowny"
||Standing on it's tail, (yes we've got to weld on a spikey tail
to prevent it doing just this in the arena) you can se the rough
position of all the electronics. The pneumatic valve block is on
the left back, speed controllers mounted on either side, pot/servo
interfaces are on the right and the laser is dangling loose on the
end. It will be a miracle if we ever manage to squeeze everything
into such a tiny box!
||Ah look at this, there are the new servo pot connections, and
the servo failsafe cut out switch. Unfortunately I've had to saw
it all up to fit inside.
