I'm building this robot out of an old printer that was laying around. It is
nothing like your normal printer cause, well, its HUGE! The dimensions
of this beast of a printer case are W-26.7", L-24", H-10.7".
Picking up the printer proved qutie a task...EMPTY. It seems the bottom
half is made out of steel I'd assume considering its weight. The printer
case is also very sturdy as I have proven by standing on the top half(which
opens), I weigh around 180 lbs, 175 on average. I will attempt to weld
an internal chassis to put into the casing as support and a place to
mount everything on. Lets just hope arc welding will come natural to
I was thinking of using the case's brute build but I thought that was
kinda boring, plus I didn't think I could obtain the proper motors to
be a brute force robot. So I had to come up with a weapon that I could
put together and if possible, have it dual purpose if it decides to
malfunction. So I threw around some ideas and thought the idea of flipping
someone up in the air would be nice and would be a crowd pleaser. Since
I didn't wanna imitate Vlad
The Impaler in its lifter/flipper design I thought of a plow. I
haven't seen a bunch of plows that functioned so I had me a weapon.
This is only my first plan that I am thinking of using, this may change.
I drew up how I would like it to look and went into trueSpace
4 and made a basic copy of the printer case, then I added a plow
and animated it and a sample pivot point. I rendered it for real time
For the plow weapon, I have two basic choices for putting it into action.
I can either use a powerful motor with a chain drive to rotate an assembly
attacthed to the arm, or I could use pneumatics/hydralics. At the moment
I'm leaning towards pneumatics in the form of CO2. It is quite fast
at moving something from point A to B and I need to learn something
about pneumatic systems anyway. I also have read that CO2 in liquid
form has a great capacity than standard compressed air and it would
proably last longer than a motor that is running along side the drive
system motor current draw. It also simplifies the amount of high current
I went down to a local surplus store to see if they had motors. This
is a picture of one of the 36v Servo
motors I picked up for $10 each. I also picked up a rather large UPS
battery but it'll be for testing. I may run these at 36v if I have the
room(and the batteries), but they turn pretty good at 24v. The draw
about 20amps a piece when stalled(I think thats how I read my multimeter),
so they aren't no Bosch 750Ws(anyone wanna donate me some?:) ). To keep
cost down, I plan to build my own.
Decided that I may want more than one weapon so I'm going to attempt
to design in a rear attack axe/hammer for anyone that attacks from the
rear or if I happen to be facing in that direction.
