EYE-FI card acquisition

On this week we acquired the SD EYE-FI card for our camera. The tests have been successful. Thanks to this new technology and the efforts of our teammate Diego, we now can take pictures and upload them automatically to facebook.

More transmission tests

First transmission tests

First transmission

Another achievement we made on this week was finishing the first transmission. Its design was made by our teammate Oscar. The following is a picture of the transmission already finished. In the following entries we will see how it works.

Changes made to the structure

To use the space in a smarter way, and take some weight off of our robot, our team chose to use a structure made of acrylic and endless screws.

We considered this to be a very good choice, because besides getting rid of unnecessary weight, the structure itself looked a lot nicer than the trash can we planned on using.

The circuitry, as well as the camera and the battery, will be set on the different levels of our structure. In the bottom part we will attach the transmissions.

Battery exchanged

One of the problems we were facing was the weight of the battery we had. We thought that our transmission wouldn't stand that much weight, besides the weight of all of the circuitry.


Luckily, while we were working on the Networking Lab, we found a similar battery, whose weight is around 1/3 of the weight of the previous one. This battery gives us 12V and 4A. We thank engineer Raime Bustos the loan of this battery for the development of our project. The battery has been set on the structure in the following way:

Sensor module demonstration

This module is part of the surveillance robot. It will be in charged of the ultrasonic sensor (SRF08) and infrarred sensors (GP2D15). For their control, we used a microcontroller PIC18F452. The programming was written in C with the CCS compiler. This module will communicate with the central module, who will be in charge of making the needed changes to the path.
