Over speed indicator and Accident Avoidance systems in a four wheeler

July 18th, 2010 by CJ Samson | 161 Comments | Filed in Automobiles, Mechanical Engineering Projects, Mechanical Seminar Topics

Except for the Autobahn in Germany, almost all roads have specific speed limits. And it is difficult for the driver to always look out for speed limits signs and adjust his speed accordingly. Over speed indicator is a device that tells the driver if he is exceeding the particular speed limit. With the over speed indicator in your car you can be sure that you are not going get yourself booked for over speeding. The system has a computer which stores the speed limits of different areas. The GPS in the system feeds the exact location of the car to the computer which looks up in its database to determine the permissible speed for the area and limits the car within the allowable speed.

Wall Climbing Robot (WCR)

July 17th, 2010 by CJ Samson | 49 Comments | Filed in Mechanical Engineering Projects, Mechanical Seminar Topics, Robots

You would rather hesitate to do the inspection and maintenance in a typically dangerous environment like the exterior of a tall building or a nuclear facility and pray to God to provide for someone else to do the same. Well, consider your prayers answered! A wall climbing Robot is willing to go through the trouble so that you can still keep smiling!

But, the idea of developing a wall climbing robot is always held back by the mighty force of GRAVITY!

And BEWARE. This won’t be an Easy Project for you. But this definitely is a fantastic Mechanical Engineering Seminar Topic, especially if you can demonstrate how it defies gravity.

You need to move against gravity to accomplish the task. Adhesion is what is required primarily, to help keep … Read the rest

Fabrication of Spark plug testing machine

July 16th, 2010 by CJ Samson | 22 Comments | Filed in Automobiles, Mechanical Engineering Projects

This is a simple mechanical engineering project which can be executed at low cost.

Construction

A Spark plug tester essentially consists of a metallic portion followed by something that looks almost similar to a Spark Plug and a connecting port in a tubular arrangement.

Fabrication of Spark plug testing machine

What does the tester do?

The Spark plug tester performs the following functions to check the proper working of the Spark plug.

1. Checks if the Spark plug is accepting current from the wires that go to the spark plug.

2. Proper firing of the Spark plug

The main idea of using a spark plug tester is to avoid the removal of the spark plug and testing it. This leads to saving valuable time.

How does it perform the above functions?

a)     Testing the wires:

At … Read the rest

Magnetic Levitation Train

July 15th, 2010 by CJ Samson | 54 Comments | Filed in Mechanical Engineering Projects, Mechanical Seminar Topics

Love to turn a 45 minute car ride to an 8 minute blur?

China was the first to country to have an up and running Maglev you could buy tickets to. Back in 1979 the Germans developed the 1st Magnetic levitation (Maglev) train.  The first to overcome the limitation of wheel and rail, because the rail moves entirely without contact!

This is a wonderful topic for your mechanical engineering seminar as well as project if you dare to make a working model.

The functions of the wheel and rail on a normal rail road including support guidance propulsion and braking are accomplished through an electro magnetic levitation and propulsion system. The mechanics have been replaced by electronics. Support Magnets draw the vehicle towards the guide way from below. While, … Read the rest

Automatic Multi-level parking (AMLP)

July 8th, 2010 by CJ Samson | 14 Comments | Filed in Automobiles, Mechanical Engineering Projects

What if you had a foot print area of 50X50 feet and you were supposed to park 200 cars in it?

After a while of using your grey cells, you would possibly stumble upon this idea called Multi-level car park (MLCP) . The idea of a structure designed particularly for Automobiles, having a number of floors or levels so as to facilitate parking.  Just the way people stack up houses to make flats! Putting one over the other so as to maximize the use of the available space.  In a MLCP you would have to seek a vacant parking slot and park your car exactly in the space provided and it might turn out to be an issue for amateur drivers! Moreover, retrieval of the car turns out to be … Read the rest

Scrap Collecting Robot

July 2nd, 2010 by admin | 36 Comments | Filed in Automation, Mechanical Engineering Projects, Robots
The intention of this mechanical engineering project is to fabricate a scrap collecting robot. Since complete automation is very complex and even research facilities haven’t come up with one, you better design one that is operated via a remote control which is either wireless or not.
This is a working project and as usual requires the help of electronics students for the control systems. This robot is 4 wheeled with an arm to collect scrap materials. It also can move over small obstacles with the support of the arm.
Though this project may sometimes look simple, it requires much effort to actually make one working model. A detailed video of one such scrap collecting robot is given below.

Ofcourse there are many other robot designs, but this one looked … Read the rest

Automatic Lawn-mover

July 1st, 2010 by admin | 9 Comments | Filed in Automation, Mechanical Engineering Projects

This mechanical engineering project requires electronic controls and sensors. Better try this in collaboration with electronics students.

The concept of an automatic lawn-mover is simple. It is a machine to cut grass automatically without human assistance. Many variety of this machine is already available in the market which have complex electronics parts. They cost around $1000.

Below is a video of a home made automatic lawn mover with a much simpler electronic parts. For your project it is better to try something like this than going for a very complex mechanism.

The main parts of this machine are:
1. Two independent motors preferably servo, if not, try Wiper motors.
2. Sensors at sides and front and the associated control units.
3. A grass cutting mechanism with an independent drive motor.… Read the rest

Auto tracking for solar panel to improve performance

June 28th, 2010 by admin | 11 Comments | Filed in Automation, Mechanical Engineering Projects, Power & Energy

The function of a tracking system for a solar panel is to track the position of the sun constantly so that the solar cells receive maximum solar energy and thereby making it fully functional.

This mechanical engineering project idea is about the fabrication of a solar panel auto tracking system. This comes under power and energy projects. The tracking system mostly consists of electronics parts. So the aim of the project sholud not be just about the fabrication of the tracking system but about energy efficianecy achieved by its implementation. It is better to get the advice of your guide on this topic.

The main parts of a solar tracking system are:
1. Solar panel
2. Servo motor or stepper motor (if difficult to find try using a wiper … Read the rest

Integration of Automatic Transmission for AutoRickshaw

June 25th, 2010 by admin | 20 Comments | Filed in Automobiles, Mechanical Engineering Projects

Auto-rickshaws have manual transmissions with 4 forward gears and 1 reverse. This mechanical engineering project is about integrating an automatic transmission to an autorickshaw replacing manual transmission gear box.

Manual transmissions are operated with the help of a clutch box, a gear knob and meshing of different sets of gear boxes. But an automatic transmission works with the help of planetary gears.

The working of automatic transmission for the project is the same as that in a gearless scooter. But here while integrating this transmission with an auto-rickshaw the size of the transmission equipment is different from that of scooter. So you will need to machine transmission elements.
