Introduction: Wireless Camera Robot
Hello all
This robot can communicate with other robots
this robot is use full in many ways suppose your child is study in his room you can see him that he study or playing suppose that a building were fell and many people want help this robot can go where human can not go this robot can programable so you can programeable so you can also play with it if you have more ideas please get me the ideas at Vishal01mehra@gmail.com
