After running dark Carrot at a couple of events several
mods have been made.
The batteries have been bulked up to 24v, to stop the relay drop out
we were experiencing at 18v, and because of the increased speed at 24v
the wheel size has dropped to 7cm. This removes the ability to do Dantomkia
spins, but doesn't warm the motors up so much, as the wheels spin.
The original ram jammed open and was replaced by a slightly heavier
item, putting the whole build a bit overweight. This could be rectified
simply, but to be honest I enter so few competitions that it doesn't
seem worth it.
The whole set up works remarkably well, and has plenty of shove, the
flipper has plenty of flip throwing out all of our opponents at the
Inspire event, Cutlet, catrip and Bodgeit, only sucmbing to Rampage
2, due to feeble driving on my part and a broken link in the nicad pack.
In theory Dark carrot is Adams robot, but it gets shared around quite
a bit.

Here
he is, built in a week, though still in need of "refining",
much of the build is "Duck taped" in place so I can do
some test runs, but The basics are in place. |

12kg's
of brutality. Power comes from 2 power devil 18v cordless drill
motord that I bought in 1999 to build our first robot wars entry...
back before I realised they weren't big enough. The speed controllers
are from KC1, a pair of ncc 35 24's, again purchase in 1999 before
I realised they weren't big enough. |
Having
said that the 35's have powered KC1, and 2 , so they work ok. Wheels
are screwed onto the drill gearbox outlet and R clipped in place.
The flipper is a Festo 40x100, that was in KC1, but broke, when
we smashed the lifting arm. It should have a tip lift of 128kg at
10bar, which results in the ability to lift about 20kgs at the tip
through a height of 60cm.
The system is powered by illegal sodastream technology that was
in KC1, with special adaptor made by Woody, cheers chap. |

The
regulator is a Oxygen cutting reg that was bought for kc1, and
the solenoid is a 5/3, In fact there are 2x 5/3 on that manifold,
and oce I've done the final weigh in I may slice off half the
manifold, as it weighs a few grammes. Chassis is absolutely gorgeous
15x15mm ERW, which welds beautifully, (if I use the decent welder
at work). The mixer will eventually be the prototype board that
Dominator team gave me to test,as Chris is sending a new production
board out for KC2.
Well,
that's all for now, Adam will be driving it at Southfields, so
the batteries are on charge for driving practice.
