Mechanical engineering senior design project UltraARM. This was a year-long project to design a robotic system that would assist ultrasound technicians in their daily tasks to help prevent musculoskeletal injuries. We were able to successfully build a proof-of-concept working prototype.
First prototype: made from Sintra, bolts and rubber bands.
Second prototype on a backpack frame with 7 degrees of freedom.
Third prototype where we changed from a wearable robot, to a mounted one. This simplified the design significantly while still performing all the necessary functions.
Fourth prototype with positional feedback potentiometers and linkage for constant angle position end effector.
The Big Check from winning first place in the Tech Titans competition. The winnings funded the remainder of our project nicely.
End effector with 3 axis force sensor. Designed and made from force sensitive resistors for $21. A commercial sensor generally costs about $5000.
