Design Progress | Week 12

Dates: 11/05/25 - 11/11/25

This week marked major progress in the final design of NAVI. Design changes to the encasing required that the previous perfboard design of NAVI be scrapped, as the dimensions were now too large. This coupled with a confusing wiring design meant a new, more refined version of the perfboard design could be developed.

This new design is about 80% complete. It has functioning power and charging components, user interface components, all 6 functioning PWM capable motors, and currently 4 functioning IR sensors.

Below are images of the nearly completed final perfboard design.

I also converted the soldered approach to the power module components with a JST connector solution - which will allow for improved maintenance of the product as well as modularity in said components placement.

Here, it can be confirmed using an IR spectrometer gun that the IR sensors which are connected to their respective voltage dividers are in fact functioning as intended (front four sensors, minus the top.)

The motors also use a dupont connection scheme which will allow for lengthening/shortening to exact final product dimension specifications.

Thus, the only remaining work is to connect the final four sensors and the internals of the device will be complete.
