Syph has been on the backburner for a while, but its now a POP and the DIY motor controller is some C-code from reality. It is my intention to have it ready for the 17th.
The form of Syph is now more concrete.
Featherweight
Drive - a single 300W oatley scooter motor
Power - two 12V 7.5Ah SLAs
Self Righting Mechanism - irrelevent for design, always vertically 'upright'
Weapon - ramming and possibly reaction arm.
Enclosure - Hexagon shaped 5mm polycarb for batteries, controller and motor.
Chassis - based on wheels and enclosure.
Wheels - two 5mm thick steel, laser cut (diatom styled for that microbe look) and one roller blade wheel on reaction arm.
Control - AT90S2313 based single channel PWM custom controller with fail-safe LED.
R/C - either the old 27 MHz stuff or new 72 MHz set (time & $ dependant)
Its not based on any previous robot combat designs as far as I can tell. The design has a few side effects some are good, one of them is that if you ram into a wall it will actually manouver its away from the wall without manual intervention. Bad side effects - it can't rotate on the spot, and directional control is possible but a steep learning curve to master (based on a dodgy scale model). _________________ "Limitation shows the Master."

Its been a long time coming along, but the wheels have been laser cut. The guys think I'm crazy, the wheels are about 30 cm diameter but have 6 metres of laser cutting because of the design, it decadent but I dig it.
Got a 75 MHz set to test out, the pollak 75A switch, two 60A relays wired, Atmel board loaded (no software as yet! you get diamonds under pressure as my old boss would say), Two bi-color 10 mm LEDs and three 40A amp MOSFETs in parallel.
Now to join them together.
Unfortunately I have misplaced the lefthand thread nut from the 300 W motor, so I have to find that baby - I don't want to think about the options in the little days I have left on this project. _________________ "Limitation shows the Master."
