I'm building a robot which will slide out of a box on a ramp that is two feet above the ground and then drive around for a project.
I'm not allowed to have the robot powered on before hand and can't physically go up to the robot and turn it on.
What's a easy and good way to have the robot turned on?
I thought of the pull-a-pin method (gravity helps pull the pin out and turns the robot on) but I'm not sure if that will work.
I don't know the rules, but if the robot is in the dark in a box and then the box is opened you could have some solar cells that once light shines on them completes a circuit that powers up the robot maybe.
You might want to put an infrared sensor on the robot, like the ones used in TV sets and then you can use a TV set remote control to turn the robot on. you can rob everything you need form an old broken TV set or VCR and remote.
At first I was going to answer sarcastically, but I realized that you were serious and also that this has potential to be really cool. Have you ever seen "The Clapper" light switch? If you modified that and clapped to turn on your robot, that would be awesome.
In all seriousness, good luck and hope it turns out well!
