Wendesday 11/3

Today we finished the basic aruino code for the movement of JAM. It is now possible to move the motors forward, backward, left and right.

Tuesday 10/3

Today we managed to build the circuits for the motors and solder them together. We also begun doing the basic structure of the robot where the wheels will be attached.

Monday 9/3

Today we finally got our DC-motors that we ordered from Conrad. We build a circuit to try them out and they worked fine. (http://itp.nyu.edu/physcomp/Tutorials/HighCurrentLoads) They are much stronger than the stepper motors and will probably be more then enough power for us. But we needed to build a circuit that could control the directions of the motor independently of each other in order to turn. After a lot of searching we found a circuit that worked: (http://itp.nyu.edu/physcomp/Labs/DCMotorControl#toc2) We can now control the direction of the motors with the bread board and will now continue by soldering the circuit, we need to build two of them in order to operate both motors at the same time.

We also begun the planing of a user study that we will carry out in order to get feedback and ideas for the robot.

First trials of the conversation the robot could do:

Monday 2/3

Today we wrote on the design document and made and the changes necessary. We discussed the results of the low-fi prototype presentation and we also had a meeting with Olof. The web cam can now detect specific objects. We also started do do some more sketches and investigated what we needed to be able to use the 3d-printer.

Monday 2/3

Meeting with olof:

3d printer: STL-file (.stl ?) Standard format, that 3d modelling uses. olof.wranne@chalmers.se.
Battery: Just buy a batteries.

Work on the personalities: What will the robot do when it meets people, when it meets then the second time.

Don't waste to much time on having maps etc in the brain. Focus on avoiding obstacles and finding people.

General look: How will it look like and so on.
