i am freshman to robot. I wan to build a robot which carried with a visible line laser. The robot could be controled for adjusting the height of the laser, also could control the switch on/ off of the laser. This is the main part of the my design. I browse the intenet and get some info, could anyone give me some suggestion which should be better
What is the LASER supposed to do?
Not just going up and down I assume.
