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.
