I am new to this community, and I would greatly appreciate some help on making my first robot. Well I say it's my first one. I've made some bristle bots, and beetle bots.
Well, my school is having a small robot war, and I'm participating..
I've drew up a simple schematic on paint.. Mainly to show the basic idea...
First, I want to explain what I would like to have on my robot. I want a robot that will move forward, backward, left turn, and right turn. I also want a set of turning "blades" on the back.
What I have.. I have my schematic set-up to where my robot can go forward, left turn, and right turn. I also have the blades set-up. It drives forward by flipping the switch for both motors. The motors are 12 to 18 V DC. I plan to power each motor by the following battery set:2sets of 9 V batteries in series and connecting those sets in parallel. So for the two main motors, I will be using 8 9V batteries. It turn by simple flipping the switch for only one motor. I have the blades set up on some motor, not sure of specification yet, but I plan to run it on a 9V battery as well.
What I need to know.. I need to know of ways to allow it to reverse. I also need to know how I should go about constructing it, in other words, is there an easier circuit to make? I didn't know if I should use any IC's or if there are any parts to make it easier to control or w/e... I also need to know how to give the commands, The only thing I know to do is wire it to a 'controller' of switches. I don't know how to go about this at all. I would like to make it wireless too.
Here's the schematic:
I also want to include a small turbo, that I will have powered by a 9.7 volt battery, in series with both of the power supplies, that way I can give a little extra push if I need to.
All tips, hints, ideas, and criticism accepted!
P.S. I would also like to know where I could get cheap products, such as batteries, components, rc supplies for the robot.. I currently use Electronic Goldmine, and looking at Futurlec.com .. Haven't bought from them yet, any reviews? Other suggestions?
