But I'd love to collaborate more if we're working towards the same goal. Let me know if this was helpful.-ilt
Yea, 6V motors sound a little weak. Ive had two robots fail in the past cause I didnt do the math, just check to make sure.As for the solenoid trigger idea, sounds like the best option - but again, verify the force first.As for wireless communication, check this post out:http://www.societyofrobots.com/robotforum/index.php?topic=104.0Search the forum for wireless, bluetooth, and easy radio too.$43 controller is actually a decent price. What is your budget?Also, although H-bridges are the cheapest since you make them yourself, motor drivers are easier and better to use if you have the money.
when I decided I'd like to build a robot I had a terrible time trying to find a definitive resource until I stumbled upon this place (which is strange, as large and diverse as the internet is, you'd think there would be zillions of robot sites).
Actually, the very first line in the datasheet says:Input voltage: 6-24V nominal, 30V absolute max.So 24V is the maximum safe voltage, but it will work just as fine on 6V. It will probably run more efficient at higher voltages, say 12V or above, just by the physics of a mosfet. But 6V will definitely work.
