remixed from the great work from https://www.thingiverse.com/thing:1681442 see it move https://youtu.be/rTlbqrB86YA -- big wheel: one side glued to the axle, other side tightened with screw (drilled a 1.8mm hole and use a 2mm screw); gear on the outer wheel is just used as spacer and also makes it look symmetrical; used 2x 2mm screws to tighten the drive gear to the wheel axle: printed with support and brim - easily removed afterwards motor support: use M4 30mm for assembly, use one M3 30mm for securing the motor - for now, please drill the missing holes in the model for connecting the motor support to brackets and mounts new pin: redesigned the pin to be slimmer to allow tracks to move easily and now I have a moving Wall-E - now I used 35 threads per side, instead of 36 **nb: the motor support may change as I've noticed the drive gear may be too close to the ground and might get stuck in the tracks as they roll below it. I use a radio-controller remote built with Arduino, similar to the one in this kit https://www.amazon.de/Adeept-NRF24L01-Wireless-Robotics-Guidebook/dp/B06XF5J52J/ -- 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/ use motor2_hat_gear for it 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 rechargable batteries --next step 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 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 for it 4x push buttons -or- none for less function 2x 3.7V rechargable 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 - it didn't - the tracks work with a redesigned 'slimmer' pin Arduino source code https://github.com/lmirel/eWall-E_r
