Talking Robots with Lego Mindstorms

From the days of "Small Wonder" TV show , I always wanted to have one robot which can talk and response just like human.To build one as Robotic Project is really interesting. This project is going to be very interesting and challenging because our robot requires not only speak capability but should have artificial intelligence to learn from its surroundings.

Architecture for talking robots consists of four main modules:
  • Dialogue system
  • Speech client with speech recognition and synthesis capabilities
  • Module for infrared communication between the PC and the RCX and
  • the program that runs on the RCX itself.

Business project ideas

 Thinking of starting a new venture and don't know how? This same problem has been faced by many of us. Starting a business looks difficult initially but it is not a rocket science. Fundamentals of business has not changed from centuries. Even though , we are living in a technology world and sometime feels that we need to think out of the box for running successful business , but in real life, we do not. In this post we will discuss about some really good ideas.Remember , starting a business is not a big deal but running it successfully requires dedication and determination.

There are lot of businesses you can do but I will suggest ideas which can be implemented with minimum or no costing at all.Look around and pick something you are passionate about :

Part Time Work having Potential to become full time :

1.Start a blog: This doesn't look like a business , but it is really good option with no investment.Wanna write one , start with blogger.com

2.Write a book: Yes, you don't need to be perfect for writing a book. Just start doing it write one page a day.Its really fun and you will able to complete  at least 200 pages at the end of a year.

3.Education Consultant: Do research about education environment, colleges , admission procedure and stuff like that and provide paid consultancy for that.

4.Property Dealer : Help sellers and buyers to get right kind of property and get hefty commission for that.

Businesses with Investment  :

Event Management Company : You can start your own event management company , which organize events such as marriages in your city.Hire some quality people from this field, they bring experience as well as contacts for you.

Distribution ship :  Get distribution ship of any reputed company with minimum presence in your city. If its possible find some new companies in the market whom you believe to get bigger by time. Advantage of associating with new company is that you will get good share in profit with minimum competition including help from the companies administration.

Auction Website like Ebay :  You can start your own auction site like ebay.With the open source community around it doesn't cost much,just download auction site code from sites like sourceforge.
 
Restaurant :  If you love cooking and have something special in that, you can start your own restaurant.For a start, you can serve only selected dishes and as word of mouth spread you can add more food items later.

Fruit and Vegetable : This business requires big chunk of land and time. Grow fruits or vegetable with working partnership with experienced local farmer. Use best technology available to make this business profitable such as Sprinklers, Drip Irrigation or Bird Scarer.

Business of Finance: This requires lot of money but you can arrange it with profit sharing basis with money lender. To run this business successfully you can ask your customer for some security like gold.

Packers and Movers: People often face difficulty to shift there offices or homes from one place to another.You can become there helping hand.

Importer : If you have good market sense , you can import cheap foreign goods from developing country like China and sell it to the shopkeepers.

Tricycle powered by pedals and electricity

An electric tricycle is a bicycle having three wheels with an electric motor used to power the vehicle.Tricycle which is powered by electricity would be very helpful for people who use cycles in there daily life. It would not only increase speed of the cycle but also helps them in paddling.


Concept :

Concept of this project is same as many electric vehicles we discussed before in Automobile Projects such as Solar Powered Cycle. It is powered by motor which is connected with battery that is charged with regular electricity available at home.
If you want , you can use some solar plates in vehicle itself to charge its batteries.


Components:
Components needed for this project are similar to those which we used in solar bicycle project and they are:

  • Lithium-ion battery 
  • DC-DC boost converter 
  • Solar panel Motor and 
  • Motor controller

Why Tricycles?
There are many advantages in using tricycle :
  • It is lighter than any vehicle around
  • It can be used to carry more than one person
  • There are pedals so dependence on electricity is not as much as motor bike.
  • Enough space to place large battery.

Can Crusher Experiment

Can crushing is very important to reuse aluminum in these cans. Moreover this contribute to significantly lower the waste management problem. These can crusher can be made to work mechanically so that no electricity is needed to crush them.


Why can crushing project is important?

Process of can crushing is very complex now. Every one throw there waste including cans to the dustbin, from there it is collected to throw in a city garbage area. Waste management people collect each can from there manually. And then these cans go for recycling in a big crusher. This whole process takes large amount of time and energy. We can reduce this problem if we crush them manually or with little electricity and then use them or sell them to aluminum buyers.


Useful Links :

Plasma Dynamic Can Crusher :  A 100 micro-Farad capacitor is charged up to 10 kV which discharges through a 3 turn copper coil upon triggering the spark gap switch. The magnetic field thus produced in the coil is so strong that any soda can, within the coil, will be crushed.

Pedal operated power generating system


 Pedal powered system can be used to recharge your cell phones, laptops or to power your camping outside. This is just a start but in future if it gets implemented in local exercise parlor and in every bicycle in a optimized way , it can produce electricity on large scale. Moreover , this method used successfully in recent wall street demonstration.



Things to know : 

Alternator : An alternator is an electromechanical device that converts mechanical energy to electrical energy in the form of alternating current.

Alternators generate electricity using the same principle as DC generators, namely, when the magnetic field around a conductor changes, a current is induced in the conductor. Typically, a rotating magnet, called the rotor turns within a stationary set of conductors wound in coils on an iron core, called the stator. The field cuts across the conductors, generating an induced EMF (electromotive force), as the mechanical input causes the rotor to turn.

Inverter : An inverter is an electrical device that converts direct current (DC) to alternating current.
