yeah, sure. well, i guess to start, the most visible stuff would be the air horn (yes, it's off a semi truck) which is on top of that BIG yellow air tank which is where the air is stored for the cannon barrel only. there are two on-board compressors that join to fill two small clippard cylinders, then go onto a T fitting where one end goes to a pressure sensor and a regulator for the pneumatic/air horn (i have yet to get another solenoid valve to overcome this problem) and the other end goes through a check valve attatched to the big air tank in front then leaves that tank to goto a electric sprinkler valve which feeds the cannon (the valve for the cannon is powered by a SPIKE relay going through a transformer that converts 12VDC to 120VAC then reduces down to 24VAC [that's what the valve requires to function fully]). it also has a rotating light on the side (and yes it came off of a snow plow) that is turned on manually with a switch. it runs off of two gearboxes, each with two CIM motors that drive push-mower wheels (two, one on each side, in the back). the robot requires two 12VDC KOP batteries to run at a very good preformance. all of this is running off of one IFI Robotics kit, of course with extra IFI parts. it steers pretty good too, seeing it uses casters. oh i almost forgot, the pneumatic is (well, was being) run off of two single action FESTO valves, it still is, just with the air horn, it automatically raises (but as i said earlier, will be fixed). in the end of production, this will have tank tracks instead of wheels (also, they will be made of hinges). overall...this has a lot of fire power for 120 PSI. if you would like to ask anything else, please let me know.
