On this Week five we had a lot of issues with the worm drive especially with the support that made worm drive unevenly

As you can see on this picture it's impossible to use the worm drive because of the scale and the support issue. The servo will not be competent to pilot this.

We will have to print the worm again drive and also make some support changes to link everything.

For the electronic part we decided to choose :

Raspberry Pi Pico W
DRV8833
Motor gear N20
Li-ion 7.4V
L7805CV
Servo-Motor FS90R

Here is the wiring diagram of the project :

The L7805CV is one of the most important part that permits the raspberry Pi Pico W to not burn with the alimentation of the Li-ion 7.4V.

The maximal tension of the DRV8833 is 10V and the N20 motor is 12V so the Li-ion 7.4V is a great alternative to manage the motor and control the raspberry with the L7805CV

For more detail go to the files and search for the datasheets.

Next week we will have to 3D print the support and an other worm drive. Also start the code to pilot the servo-motor and the N20.
