Scrap Collecting Robot

On July 2nd, 2010 by admin | 36 Comments | Posted 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

On July 1st, 2010 by admin | 9 Comments | Posted 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

On June 28th, 2010 by admin | 11 Comments | Posted 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

Automatic Rain Operated Wiper

On June 25th, 2010 by admin | 106 Comments | Posted in Automation, Automobiles, Mechanical Engineering Projects

This Mechanical engineering project requires the help of electronic components for working. The design of automated rain operated wiper is based on an electronically controlled motor whose controls are actuated by the presence of water droplets.

The required components for this project are:
1. A conduction sensor circuit
2. Control unit
3. A wiper motor
4. A glass frame

 

AUTOMATIC RAIN OPERATED WIPER
SYNOPSIS
The aim is to design and develop a control system based an electronically controlled automotive rain operated motor is called AUTOMATIC RAIN OPERATED WIPER.

Rain operated motor is consists of conduction sensor (Tough sensor) circuit, Control Unit, wiper motor and glass frame. The sensor is used to detect the rain or water flow. There is any rain on the class, the sensor senses the rain … Read the rest

Integration of Automatic Transmission for AutoRickshaw

On June 25th, 2010 by admin | 20 Comments | Posted 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.

Fabrication of Motorized Screw Jack for vehicles.

On June 20th, 2010 by admin | 137 Comments | Posted in Automobiles, Mechanical Engineering Projects

Motorized/Automatic Screw Jack for vehicles

Fabrication of a motorized screw jack is easy especially when the parts are avaialble in the market. This mechanical engineering project can be easily completed by integrating an electric motor with a screw jack.

A screw jack or a Jackscrew is operated by turning a lead screw. The height of the jack is adjusted by turning the lead screw. This can be done either manually or by integrating an electric motor with it. This integration is our project.

The difficult part in the project may be finding a low speed motor that is able to work at 12V. This is because the battery output of an automobile is 12V, and the electricity needed for the operation of the screw jack is taken from this battery. … Read the rest

Fabrication of Solar Car

Solar Car Design-How to Build a Solar Car

The title of the project may be misleading, because it not going to be easy building a full sized solar car. It is not only difficult but also very costly. So it is better to do this as a project which includes lots of study and then a demonstration of how the solar energy can be converted and stored in batteries and then how it can be used to run the vehicle. May be with the staffs permission you may be able to use your college’s water heater solar panel if there is any. The design part of the project includes lots of calculations on how much energy can be stored, how fast the energy can be stored, how maximum efficiency … Read the rest

Fabrication of Gear Level Indicator for Automobile

On June 19th, 2010 by admin | 11 Comments | Posted in Mechanical Engineering Projects

This is a simple mechanical project which requires some knowledge of electrical and electronics. I believe that kits for an automatic gear level indicator is available in market.

An automatic gear level indicator digitally displays the gear on which the vehicle is currently running. It doesn’t observe the transmission directly, instead, this is done calculating the speed of the vehicle and the rpm of the engine and then comparing both. The speeds of a vehicle are different for different gear levels even when the rpm is kept same. So by calculating the speed/rpm ratio for each gear level, the gear positions can be detected and displyed using an LCD screen. This will be different for different vehicles, so it is a must that you check these ratios with your experiment … Read the rest

Fabrication of Electromagnetic braking System For Automobile

On June 18th, 2010 by admin | 38 Comments | Posted in Automobiles, Mechanical Engineering Projects

Electromagnetic braking System

This is one of the simplest mechanical engineering projects. An Electromagnetic Braking system uses Magnetic force to engage the brake, but the torque required for braking is transmitted manually.

The main parts of an electromagnetic brake are:
1. The coil
2. The armature.
3. The hub.

The hub is attached to the axle of the vehicle. The armature is mounted on the hub and rotates along with it. The coil is mounted on a stationary element attached to the machine frame of the vehicle. Two friction plates are mounted each on the face of the armature and the machine element holding the coil.

Working:
Electricity is applied to the coil at the time of braking. This develops a magnetic field around it and the rotating armature gets … Read the rest

Turbocharger for two wheelers

On June 17th, 2010 by admin | 97 Comments | Posted in Mechanical Engineering Projects

This mechanical engineering project deals with turbocharging a two wheeler.

Turbocharging is usually carried out in diesel engines. This is because turbocharges work using the pressure from the exhaust gas (For diesel engines the compression ratio is high and hence the pressure.). But it can be used in petrol engines also if the engine is 4 cylindered or more.

Turbocharging a bike is possible only if it is a 4 cylinder one. Usually only performance bikes are turbocharged. It is also possible to improve the performance of a bike using nitro injection, bigger carburettors etc, but the advantage of turbocharging its stock engine is that you save a lot of money and at the same time obtain better performance.
