Robo master/slave project
Has anyone fabricated a master robot/slave confab? I am working on a moving target concept and have hacked a power wheels (type) ride on jeep for kids. It is capable of packing 60 pounds in semi-rough terrain so it has the beans to pack a 20 pound load. Currently the vehicle has remote control which works fine for a team shooting practice, but I hoping to guide the jeep with a robo brain. My first test will be with a robo vacuum that has a simple pattern governed by a front bumper that makes it go in to reverse and turn. I will use the signals from the robo vac to fire relays that will fire the jeep drive motors. On paper it looks very workable, but I am waiting on relays at the moment so when they arrive the real world test will be conducted.
If the robo vac works as planned my next step is to use a S2 to control the jeep. I am currently learning the GUI for the S2 and this approach will give the Jeep more options in movement. It appears I will have to suspend the S2 on a frame so the wheels can turn and send signals to the jeep drive relays. It looks like the biggest challenge will be to find 9 volt relays for the S2 to Jeep relays.
One might ask why use a master/slave configuration? My thoughts were to save time and money whereas the Jeep was right at $200 and saved the cost and time of fabrication of a frame, purchasing motors,etc. I am not experienced in programming so using the S2 brain will save me lots of time, and the motion patterns I need will be basic. The shooting range will relatively free of objects so a timed travel in one direction or another should suffice.
I do have a remote kill switch if things spin out of control and the shooters are attacked by the target.
So any thoughts, comments experiences will be appreciated.

How are your turning the steering wheel? Those Power Wheels typically use two seperate motors on each of the rear driving wheels in lieu of a differential.
Relays are simple enough to use, even with a modest BS2. You can program such a bot to run specific patterns if you want to add wheel encoders: https://www.youtube.com/watch?v=PX0IhUqnwrk
Are you planning to take the wires off the S2 motor and hook them to a relay? That won't work.
Likewise apples & oranges on the two chassis designs. Your power wheel uses more complicated Ackerman steering, completely different from the simple differential steering on the S2 and Roomba. No easy way to mix the two.
Suggest you start small and work up to a power wheels size bot.
What program and micro did you use in robo that remembered the path?
