Human: Inspired by the brilliant work on Thingiverse, I created my own remix of this incredible project (https://www.thingiverse.com/thing:1681442). Watch it in action here: https://youtu.be/rTlbqrB86YA. To build the big wheel, attach one side to the axle with glue and secure the other side with a screw (I used a 1.8mm hole and a 2mm screw). The gear on the outer wheel serves as a spacer and adds symmetry; I tightened it using two 2mm screws. For the drive gear, I attached it to the wheel using two 2mm screws. The axle was printed with support and brim, making it easy to remove afterwards. For the motor support, I used an M4 30mm screw for assembly and an M3 30mm screw to secure the motor. However, please note that you'll need to drill additional holes in the model to connect the motor support to brackets and mounts. I redesigned the pin to be slimmer, allowing the tracks to move smoothly. This enabled me to create a moving Wall-E - I used 35 threads per side instead of 36. Please note that the motor support may change as I've noticed that the drive gear might get stuck in the tracks when they roll below it. I built a radio-controller remote using Arduino, similar to this kit: https://www.amazon.de/Adeept-NRF24L01-Wireless-Robotics-Guidebook/dp/B06XF5J52J/. Here's the BOM for eWall-E: * Arduino Nano (https://www.amazon.de/Elegoo-Entwicklerboard-Arduino-Atmega328P-CH340/dp/B0713ZRJLC/) * Radio Module NRF24L01 (https://www.amazon.de/AZDelivery-NRF24L01-Wireless-Arduino-Raspberry/dp/B06XJN417D/) * 2 Gear Motor Dual Shaft (https://www.amazon.de/dp/B06XSJS8W6/) using motor2_hat_gear * L9110S H-Bridge Dual DC Stepper Motor Driver Controller Board for Arduino (https://www.amazon.de/iHaospace-H-Bridge-Stepper-Controller-Arduino/dp/B07PKC4FFG/) * 2x 3.7V rechargeable batteries Next steps: * 3x servos: 2x for hands, 1x for head * Sound support (https://www.amazon.de/Cylewet-DFPlayer-Mini-MP3-Player-Modul-unterstützt-TF-Karten/dp/B071147RGH/) Here's the BOM for Arduino remote for eWall-E: * Arduino Nano (https://www.amazon.de/Elegoo-Entwicklerboard-Arduino-Atmega328P-CH340/dp/B0713ZRJLC/) * Radio Module NRF24L01 (https://www.amazon.de/AZDelivery-NRF24L01-Wireless-Arduino-Raspberry/dp/B06XJN417D/) * 2x analog joysticks w/ push buttons - or - just push buttons * 2x pots for trimming speeds - or - none if you don't care about it * 4x push buttons - or - none for less function * 2x 3.7V rechargeable batteries Unfortunately, I didn't have time to draw the schematics yet. Notes: * The track plates won't work if they are stiff, so check your prints! I used flexible material for threads but those tend to get loose from pins after a while - might try a mix of flex and PLA to see if it works better. * The tracks work with a redesigned 'slimmer' pin.
