higher fidelity prototype & mechanics issue #1

We cut the black satiny fabric into a shape that would do away with all the extra fabric to help with the weight of the skirt. The hoops were loosely sewn to the skirt. We fond that the hardest part of the twist ties was to find something strong enough to get rid of the locking part of it. It made a tear drop shape more than a circle. After some digging in the engineering lab we found some sheers and used those.

For the motors, we had to create the means of powering them. They spun insanely fast but they were having a hard time pulling up the lightest loads. What was more disconcerting was the issue of the pulley mechanism. The system we have figured out is one where the skirt hoops are threaded through with string and the string is attached to a a spool which is attached to a motor. Once the motor is started in a direction, the string will wrap around the spool, pulling the hoops and skirt up. If we wanted to drop the skirt, we’d just need to reverse the motor’s direction.

The issue was that the DC motors did not work with the Lego pieces we had so we would need to custom make the spool if we were to use the DC motors. In addition, we would lose the up and down functionality for the most part because we had not figured out how to program the DC motors.

So it was back to the drawing board.
