Q. How can this robot can help people?
There has been a lot of concern lately about fireworks maiming and injuring the person igniting it and a few cases of fatalities.
This autonomous NXT robot will light multiple fireworks in a sequence - while the family sits back and watch the display!!
It uses a MINDSTORMS NXT, two light sensors (one for navigation and other to detect a lighted fuse), and an Ultrasonic detector (to adjust the torch arm height depending on the height of the fireworks fuse wire. It uses three motors - two for motion and the third for the torch arm elevator.
