Design Progress | Week 9

Dates: 10/15/25 - 10/21/25

This week I created the final prototype for the haptic/IR cooperative system. This prototype takes advantage of the 8 motors being controlled through the darlington array, as well as the (currently 5) IR sensors sending data to said motors, into the Pico 2 from the ADC multiplexer. The system also makes use of the production system battery, as well as the 5V boost converter.

The only things now missing from this system are the buttons (awaiting delivery) for UI control, the charging module (already tested with production battery and pico), the three remaining IR sensors, and soldering into final prototype boards for seating into the final enclosure.

I plan to have the final production system soldered together and placed in the NAVI enclosure by the first meeting in November.

Below is a demo video showcasing this week's accomplishments.
