my team is thinking about using a tape measure like device where it retracts onto a spool when our arm restracts. Our arm reaches about 8 feet, so ours would need to be a bit more extensive. And we have 48 hours till ship.

Teams have used this type of device in the past. The ones I have seen are commercially available cable reels. You can easily make your own by using a spring driven drum, and attach the midpoint of your wiring to the drum and place the drum so it is halfway up your elevator when it is fully extended. As the assembly comes down, both the upper and lower portions of your wiring will wind onto the drum. If you must keep the drum mounted on the robot and only pay out wire as the elevator rises, then you need a device that has an internal slip ring assembly. |
