Anyone who has ever had to walk on crutches knows how difficult it can be to carry things, especially a cup. To solve this common problem, Team Carry Crutches developed a self-stabilizing cup holder that attaches to a crutch and can hold a beverage without spilling it. The team designed a 3D printed gimbal inspired by those used to steady a camera on an aerial drone. The team developed two versions of the cup holder: a mechanical version that costs only $15 in materials and combines 3D printed parts with ball bearings, and an electronic version features a Raspberry Pi, servo motors, and an accelerometer and costs $30 to build. "We know that sometimes, helping people do the simplest tasks can have a tremendous impact, that's why our team created the Carry Crutches," said Tomas Garces, a design engineer at General Electric Firstbuild. "To have a person on the team who has a need for the device was integral to our design process and we look forward to seeing how people on Thingiverse improve upon it.” The 3D design files for Carry Crutches are available on Thingiverse.

Team members: Benoy Bhagattjee, Daisy Bermudez, Ilan Sherman, Maayan Dremer, Matthew Wasala, Tomas Garces.

"The team developed two versions of the cup holder: a mechanical version..., and an electronic version features a Raspberry Pi, servo motors, and an accelerometer and costs $30 to build."

Please explain to me exactly how the electronic version only costs $30, when the Pi itself is usually $40? Do they know of a discounted source that I don't?

Either way, I would go with the simple ball-bearing design, assuming it's pretty smooth...sometimes simplicity is best!

BTW, Great Job!!

The parts list shows an Arduino, so I think the Raspberry Pi might be a typo. That said, I tend to agree, the costs of the Arduino, servos, and Triple axis accelerometer are going to run greater than $30 at qty 1. Maybe in volume???
