Creating A Rescuebot

hello friends, 😎

I m a mech engg stud.... planning for preparing a robot which can be used for rescue purposes and which can be used by bomb diffusal squad.

So, I wanted ideas regarding how to prepare metal detectors...... ideas regarding integrating webcams in to the robots .........making the robots more flexible .........and intergating them with computers for controlling purpose........please help me........

Though it is a costlier project..... there is no budget limits.......

Thanx
