Automatic Guided Vehicle

In this bachelorthesis project which I took part in, we developed an Automated Guided Vehicle, that could locate and navigate itself in a limited space. It sensed reflectors by using a one dimension infrared laser and used this to calculate it’s position. With an Arduino Mega it controled the motorspeed of the two tracks (powered by two Biltema screwdrivers), and at the same time communicated with the server.

Here’s a wrapup from the presentation of the project:

There where lots of test before the project was completed, here we tryied out the manual control on a laptop via bluetooth.

There where also a previous project the year before, this was their result:

Food printer.

A concept design project named Cornucopia presented by MIT has a new take on the environmental problems in the food industry such as transportation and waste of food. It is estimated that the waste of meat is equivalent to 100 000 pigs/year in Sweden alone according to ”food for a better climate” ( in Swedish), add to that all other products with an expiration date and the numbers becomes staggering. We could of course shop locally to avoid unneccesary transportation and minimize the impact on the environment but how do we solve the issue of us throwing away food? This is where the foodprinter enters the scene. Simply put it has a series of canisters with basic ingredients which can be mixed, chilled or heated and then used to create any number of dishes. It doesn’t get any greener than that.

Above is a picture of the Cornucopia, on top are the canisters with basic ingredients to be used to “print” the dish.

Wii Nunchuck for Arduino

I found the technology of this project (“Control Your Robot Using a Wii Nunchuck (and an Arduino)”) to be interesting as the Wii Nunchuck might be a useful input device in future projects.
