-We found that many of our pieces could be smaller, which would decrease the amount of delrin we would use. For example, our front and back pieces were slightly too wide and a lot of plastic was sticking out on the sides. So we decided to make the widths shorter. By better matching the width of the front/ back pieces with the length between the two side pieces, the robot also looked a lot better.
-We also made an adjustment to our side pieces. They seemed a bit too long and we wanted the motor and the battery to fit perfectly inside the robot. Therefore, we decreased the size of the side piece by 6mm.
-When assembling the parts, we found that our bottom piece had the completely wrong dimensions. The length was much shorter and the width was much to long. So we made the adjustments and continued assembling the robot.
This is a picture of the assembly:
The legs and feet are connected to the robot with press fits, so were not able to show this on SolidWorks, but we placed the pieces in their intended locations.
After making the assembly we made a drawing of all the pieces we need so we could start printing out the pieces. Here is a picture of the drawing:
Then we proceeded in printing out the pieces. Because we had a lot of pieces, the printing took a long time. Here is a picture of the laser printer at work:
During class, we also assembled our motor. The only problem with it is that the shaft is not as long as we wanted it to be. We also need a single shaft, not two, since we want the circles to rotate at the same time. Professor Berg ordered some new pieces, so hopefully they would work with our design.
