Hey all,
I'm working on a project and could use some advice for a component part. The project is a small robot that's about two inches long. The robot needs to have some kind of microcontroller-controllable retractable/expandable rod or arm that fits within about an inch space, but can expand out to about 3 inches. That arm will have a sensor on the end and reach out and "touch" things. I'm not sure what to do for the expandable arm component. I've been thinking of some kind of electronic antenna (telescopic antenna) thing, or a solenoid (but these don't seem to run on 5v - 12v and have that length of stroke), but I could really use some help!
Of course the cheaper and sturdier the better (because if the robot runs into a wall, I don't want the arm to bend).
Thanks in advance.
