first time feather build

**chris knee** · 19th November 2012, 19:38

hi guys, i think i have nearly everything to start work on a new feather, the only thing i think im short of is a firing mechanism for a co2 flipper,does anyone have any ideas what i might need for this please, i have got 2 gimson gr02 motors, 2 electronize speed controllers, i have a radio that came with a reciever, a vast amount of 20mm angle iron, a pair of banebot wheels, an old co2 fire extguisher, and a regulator, is there anything else i need?

Quite a lot missing from that list, but I assume you have some of it and just haven't listed it?

From the pneumatic side of things:

Some sort of solenoid valve and a way to fire it, the ways i've used is a switch pressing a servo or a Battleswitch.
Ram
piping, connectors, etc...
on/off valve for the CO2 tank
buffer tank (optional)

Possibly more but I can't think off the top of my head.

sorry forgot to say i got loads of tubing and elbow joints and other bits and bobs,

A dump valve is needed, just an on/off valve with one port open from the air would do. Needs to be accessible though

right, i seem to have all the parts now, motors, speed conrollers, ram, co2 bottle, tubing, valves, batterys, wire, a lot of angle iron, now where do i start lol

What kind of shape do you want to build, do you have any plating / armour?

i havent thought that far ahead yet lol, its going to take an age getting all the bits together in the right order, i was going to make the chassis out of 20mm by 20mm angle iron, then put in some kind of base plate to attatch all the gubins to, but i got to be careful not to get to heavy,

Before you spend an arm and a leg sit down and decide what you want to build first. As a first time builder I'm realising that robot building isn't the cheapest thing you can do, and that you'll throw money away buying parts randomly without an idea of where the robot shape/design is going.

having doodled for a bit i have now come up with a sort of idea for a bot, but i am having problems with the pnuematic side of things, i intend to have a sharp pointey thing attatched to the main stem of the ram, and have it fire out of the front of the bot, i am unsure of how to fire the thing, do i put two co2 pipes on it, one for firing out and another on the other end to retract it, or do i do what some flippers have, a bungy to retract the weapon, also could anyone point me in the right direction for the components i will need for a firing mechanism, it is a low pressure system 20oz co2 bottle, trevor reg, 10mm nylon tubing
thanks guys
