Let's Make Robots!


laser pointer and a 38khz sensor

would it be possible to make a laser flicker at 38khz?

I was thinking; if I had a modified laser that gave me a red dot that pulsed at 38Khz. If a robot was made to go towards a 38Khz beacon...

I thought this might function as a intuitive remote control.

The robot is programmed to do whatever, map its surrounding, search for metal or filming the girls gymn locker room. But when the laser is pointed anywhere in its vicinity it'll start following the red dot until the laser is switched of again. then it will continioue its original task.
