Dig the line follower at 3:05! Hey, this stuff really works!!
Speaking of line following, my girls have been playing with secret messages invisible ink pens, which write in ink only visible when you shine UV light on it. I have half a mind.
... to try to make a line follower robot that could follow such a line. Anybody ever seen that?
I was reading some hackaday stuff this morning, and came across Kiva Systems (now AmazonRobotics). If you liked the line-follower in the OP video, you'll really like this!
