sir, I'm a newbie here.. this is my first time in making a robot.. please tell me step by step on how to make an adaptive mapping robot without using the irobot.. I'm making a robot from a scratch, from designing to making sensors, wires, etc.. please help me.. i have proposed already a proposal about this project and been accepted already by my professor.. i ask an opinion from the shop and told me that i must use a gps, servo motor, stepping driver.. i don't know what i lack and how to connect them..
