wall climbing robot moving through ceiling

wall climbing robot moving through ceiling.
This robot was developed by us.
Its weight is 1.2 kg, the existing wall climbing robots are with less weight & high cost but our robot frame is made up of aluminium sheet, which will reduce the cost of the robot.
For sticking the robot to the wall vacuum producing impeller are used which is modified by us.
We modified the four wheels for providing proper grip and for maintaining the ground clearance.
For ground clearance we used rubber strip.
Our robot can carry extra 1 kg of weight by reducing its frame weight.
