Pico Bot

A desktop bot for fun... wobbles around, falls over, blinks and shows the data from the gyro and accelerometer.

Components

• Waveshare Round LCD with RP2040 - https://thepihut.com/products/round-1-28-lcd-display-module-240x240-ips-65k-rgb
• 600mah 1s battery
• Tiny switch
• Tiny button
• 8 x 1mm magnets

Micropython

You'll need 1.19, not all firmware appears to work, if you have problems try the one included here https://www.waveshare.com/w/upload/9/9d/RP2040-LCD-1.28.zip to test your device. You'll then need download the "Pico with Pimoroni Libraries" via Thonny or https://github.com/pimoroni/pimoroni-pico/releases

All this because I used the ellipse method in framebuf which didn't appear till 1.19. Apparently circles are cutting edge and only just released!

Printing

Printed on an Ender 3 Neo v2 with standard settings and PLA filament.

Painting

Sanded down and a couple coats of primer, 4 - 5 coats of spray metalic silver paint. Photo really shows up the layer lines, it's much less noticable in real life and has quite a nice gloss finish.

pico-bot's Issues

Make it wobble but not fall over

Suspect this is a complete redesign in Fusion360.

Idea from Reddit to add rounded feet to make the correct curve on the bottom without touching the main body.

The button isn't connected to anything

Wire it up, first two pins on left header? Maybe..

What does it do..

Cycle through the display modes
Press and hold - make funny face / or go to sleep

Eyebrows - add and control them

One for each eye

Animated in the same way as eyes are

Eye animation and control - open, close, look...

Eye API

open(25) - Open the eye to 25%
open(100) - Open fully
open(0) - Close
look(90) - Look right (90 degrees)
speed - speed of movement?

Continue with idea of a target Eye, compare and adjust each frame
