Help with Micro/Mini Gearhead motors for tiny bot
July 20, 2012
Ok so if you've read my profile here, one of my goals is to create/produce a low cost, versatile micro/mini robot that could be used as a swarm bot.
Currently I'm trying to source some decent tiny gearhead motors for under $12 dollars. Today I've come across these:
Also there are some 3V gearmotors of the same dimensions with varying RPMs (from 30 to 100rpm) available as well. The torque ratios are not given for those, however.
Now my question to all of you is, which motor(s) do you think would be better for this project?
Here are some details:
2" x 2" plastic platform
12mm diameter wheel (approximate)
All combined (electronics, motors, battery, platform), we're probably talking weight in the ounces.
What do you think would be a decent RPM speed? And if I go with the 6v motors do you think I could get away with feeding them around 4.5 volts? I've seen some similar gearhead motors that accept voltages ranging from 1.2 to their max 12vdc. Not sure if all motors are like that or if some have specific vdc required.
Any help would be appreciated!
