Hardware files and code for Crimson Dynamic (HAX Shenzhen 2019) sensor system prototyping
Design a sensor system that adds value to the exoskeleton, specifically for use in an overhead assembly line in car factories. Potential insights the sensor system could provide:
- Task compliance: ensure a worker did not forget a bolt/nut on a car
- long term vibration exposure
- long term arm fatigue
- long term noise exposure
- etc.
Sensor breakout to count the number of overhead drilling actions accomplished. Looked into doing an FFT analysis on IMU data and microphone data. Decided to settle on matching IMU data peaks to microphone data peaks. The same two sensors could be use to quantify the long term exposure to vibration, noise and fatigue.
Pi HAT with sensors and UI to count the number of overhead drilling actions accomplished. A more efficient rendition of REV1 that is usable for demonstration.
Note: Data is post processed and results are not given in real time
NRF52 based sensor node with only IMU to monitor limb motion and vibration
