Project Summary

Our task is to make a wall climbing robot with help of electrostatics adhesion force between the pad and wall which is cost effective, less power consumption and require less area. We will work to produce more adhesive force in less area of conduction plates. Another main task is to control the robot by using microcontroller. It can climb over different surfaces such as glass, concrete, plastics, wood and conducting materials. Our project is a protype which will carry light weight but if we increase the DC voltages to electrodes then it is able to carry heavier weight. It is applicable in construction sites etc.

Project Objectives

1. objective to control the speed and movement of our robot. For demonstration, we will design and fabricate a robot which is able to carry some weight at certain height. Our main goal is to make a robot which is cost effective, have relatively lower power consumption, and requires minimum area to produce strong adhesion force.
2. We will observe low AC voltage to high AC voltage by step-up transformer and after this conversion of high AC voltage to high DC voltage through rectifiers and capacitors. The high DC voltage is then given to electrode.
3. We will experimentally and theoretically explain the unipolar and bipolar electrostatic adhesion forces. unipolar electrostatics is quite simple than bipolar electrostatic. Unipolar electrostatic adhesive pad gives more strong adhesion forces and comparatively stretchy than bipolar. Bipolar adhesion pad is commonly used where we need less area and strong forces. Combo type forces is known as bipolar adhesion forces.
4. We will use microcontroller (PIC15F876) to control the movement and speed of robot with the help of rotatory holder and range sensors. Our prime purpose is to carry weight with robot.  

Project Implementation Method

The entire setup can be analyzed using hardware equipment. Any error occurred can be removed after multiple trials to achieve perfection.

Results Expected

 By the grace of Almighty Allah,

1. We will construct a wall climbing robot having vertical motion (backward and forward motion)
2. We will develop an electro adhesive pad that:

1. Can hold a wall climbing robot whose weight will be around 700 grams.

Will use a maximum of 20kv high voltage DC.

Benefits of the Project

         This SDP results will provide the basic concept for the design and fabrication of a wall climbing robot and the phenomenon of electrostatics related to it. With the help of these results, engineers can make similar robots performing different tasks. In this era, there are many high buildings, and their windows are at very high altitude. Engineers can design and develop the robots for window cleaning purposes by modifying microcontroller and different motors. These robots can also be used in industry to carry raw materials in manufacturing chamber which are at some height. Such wall climbing robots are also very useful when investigating any kind of leakage and cracks in underground storage tanks. By just installing a camera on robot, we can get the visuals of these cracks which cannot be observed by workers due to their location.

Technical Details of Final Deliverable

By using the Step-up transformer, we will obtain HIgh AC upto 2.5kvvoltages. Hight AC voltages is converted to high DC voltages by Cockroft-Walton multiplier circuit. After that high DC volatges given to the PAD of Robot For Climbing purpose.

By the help DC motor, Tail of robot, Lower module connector, Microcontroller (PIC16F876) Rotatory holder  and Energy receiver, we control the Robot the Surface of wall.
