The document summarizes a wall following device that can follow a wall without sensors by using limit switches. The device uses two limit switches, two 60 rpm motors, wheels, batteries, and connecting wires. The limit switches control the motion of the wheels by turning the power to the motors on and off. When the device touches the wall, the limit switches help the follower turn and continue along the wall. The wall following device is cheaper than sensor-based options and can work in various conditions. Potential applications include research in wells or on planetary surfaces.

More than thirty years of research and application experience have led to Active Magnetic Bearings (AMB), which allow unique applications for rotating machinery with excellent performance. The main part is devoted to recent research topics, as a challenge to young researchers in rotor dynamics, mechatronics design and control. Active magnetic bearings, a typical mechatronics product have been successfully applied in industrial turbomachinery. Their main advantages are the contactless working principle, the frictionless suspension, and that they represent an active system. Therefore, the active magnetic bearings are well suited to operate contactless as actuator and sensor elements in rotating machinery. The report describes about the construction, working principles, advantages, disadvantages, applications & uses of AMBs. A unique aspect of the design is the two additional radial AMBs to allow the application of simulated destabilizing fluid or electromagnetic forces to the rotor. These forces are difficult to predict and can lead to rotordynamic instability of industrial machinery if not properly accounted for. The AMB provides a realistic platform to evaluate stabilizing control algorithms for high performance turbomachinery.
Advances in magnetic material, control have contributed to the realization of completely non-contacting relating systems employing magnetic bearings to eliminate the last remaining wear out prone element. Current efforts are being directed more towards reducing the size, weight and complexity of these devices to achieve complete acceptance.The AMB technology has been briefly reviewed including its advantages, components, working principles, cost and performance. Some design and Implementation issues have been also discussed.
The taking into consideration the above advantages, the adoption of magnetic bearings in industry will be more economical, efficient and environment friendly compared to the conventional bearings. The authors believe that AMB systems are still relatively more expensive than conventional mechanical bearings; therefore the massive used of AMB in industries is still prohibitive despite of the many benefits offered. The AMBs will still not completely replace conventional bearings in rotating machinery in the near future. However, AMB can find its place well in a limited volume of high performance rotating machines.

3. INTRODUCTION
• This is a wall following device which can follow the wall
without programming.
• Range detectors are replaced by Limit switches.
• Limit switches are used to control the motion of wheels.
5. OBJECTIVE OF PROJECT
• To discard the use of sensors and other microchips and full fill
our goal. i.e. Follow the wall.
• To reduce the cost of the system.
• To make workable on under any circumstances.
• Free from environment effect.
6. COMPONENTS
• 2- Limit switches
• 2- 60 rpm motor
• 2- 7cm diameter wheels
• 12 volt-Battery
• Power switches and connecting wires
7. LIMIT SWITCH
• Limit switch are automatic switches.
• They control the wheels by turning power on and off according to
the motion desired.

9. STEPPER MOTOR
• A stepper motor is an electromechanical device which converts electrical
pulses into discrete mechanical movements.
• The shaft or spindle of a stepper motor rotates in discrete step increments
when electrical command pulses are applied to it in the proper sequence.
• The motors rotation has several direct relationships to these applied input
pulses.
• The speed of the motor shafts rotation is directly related to the frequency of
the input pulses and the no. of rotation is directly related to the number of
input pulses applied
11. 12V-BATTERY
• Batteries operate by converting chemical energy into electrical
energy through electrochemical discharge reactions.
• Batteries are composed of one or more cells, each containing a
positive electrode, negative electrode, separator, and electrolyte .
• Cells can be divided into two major classes: primary and secondary.
• Primary cells are not rechargeable and must be replaced once the
reactants are depleted.
• Secondary cells are rechargeable and require a DC charging source
to restore reactants to their fully charged state.

14. WORKING
• There are two limit switches in the front of device as it touches the
wall it will work and help follower to turn.
• The function of both switches are :
a) At normal position the motor rotates and follower starts moving in
forward direction, if any restriction come in the way the limit
switch is pressed then NC starts reacting as NO and NO as NC.
b) So one motor is stop while the other is keeps rotating.
c) So the device turns and follow the wall.
15. APPLICATIONS
• If spiral type well is there, then we can use for some research in the
well.
• It can also be used in doing research on planets with unknown
surroundings, it will walk on the surface of any planet around the
space shuttle and we can observe the surface of planet.
• It can be used in long pipes to check the fault ,if any.
16. COMPARISON
Wall follower with sensors
• It is very costly due to use of
different types of I.C’s and
other sensors.
• Limited application due to
surrounding conditions like
high temp, pressure etc.
Wall follower without sensors
• It is cheaper as no I.C is used.
• Limit switches works
efficiently in any condition.
17. CONCLUSION
• A comprehensive introduction to the hardware design of a wall
follower robot, the wall - follower is shown in this report. the
robot works pretty well and shows a great potential for future
uses.
18. FUTURE SCOPE
• Sensors can be attached to the followers to detect the presence of
harmful gases, chemicals etc.
• A flying wall follower is a possibility in which limit switches can be
used to control the direction by controlling the propellers.
