Week 3:

During week 3, Group 6 programmed the NXT Robot to move a few inches and then play notes at random. The pneumatic part of the organ was dealt with manually; one of the group members simply blew air into it. It was originally put on a track which was created using Lego pieces and duct tape. This track, as seen in Figure 1, was put in place to circumvent the problem of having the NXT go where desired. Using the Lego pieces for the track was not very reliable so we decided to go with the idea of buying a gear track which serves for better control.
