<p>remixed from the great work from <a href="https://www.thingiverse.com/thing:1681442">https://www.thingiverse.com/thing:1681442</a></p> <p>see it move <a href="https://youtu.be/rTlbqrB86YA">https://youtu.be/rTlbqrB86YA</a></p> <p>--</p> <p>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</p> <p>axle: printed with support and brim - easily removed afterwards</p> <p>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</p> <p>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</p> <p>**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.</p> <p>I use a radio-controller remote built with Arduino, similar to the one in this kit <a href="https://www.amazon.de/Adeept-NRF24L01-Wireless-Robotics-Guidebook/dp/B06XF5J52J/?tag=thingiverse09-20">https://www.amazon.de/Adeept-NRF24L01-Wireless-Robotics-Guidebook/dp/B06XF5J52J/</a></p> <p>--</p> <p>BOM for eWall-E:</p> <p>Arduino Nano <a href="https://www.amazon.de/Elegoo-Entwicklerboard-Arduino-Atmega328P-CH340/dp/B0713ZRJLC/?tag=thingiverse09-20">https://www.amazon.de/Elegoo-Entwicklerboard-Arduino-Atmega328P-CH340/dp/B0713ZRJLC/</a></p> <p>Radio Module NRF24L01 <a href="https://www.amazon.de/AZDelivery-NRF24L01-Wireless-Arduino-Raspberry/dp/B06XJN417D/?tag=thingiverse09-20">https://www.amazon.de/AZDelivery-NRF24L01-Wireless-Arduino-Raspberry/dp/B06XJN417D/</a></p> <p>2 Gear Motor Dual Shaft <a href="https://www.amazon.de/dp/B06XSJS8W6/?tag=thingiverse09-20">https://www.amazon.de/dp/B06XSJS8W6/</a> use motor2_hat_gear for it</p> <p>L9110S H-Bridge Dual DC Stepper Motor Driver Controller Board for Arduino <a href="https://www.amazon.de/iHaospace-H-Bridge-Stepper-Controller-Arduino/dp/B07PKC4FFG/?tag=thingiverse09-20">https://www.amazon.de/iHaospace-H-Bridge-Stepper-Controller-Arduino/dp/B07PKC4FFG/</a></p> <p>2x 3.7V rechargable batteries</p> <p>--next step</p> <p>3x servos: 2x for hands, 1x for head</p> <p>Sound support <a href="https://www.amazon.de/Cylewet-DFPlayer-Mini-MP3-Player-Modul-unterst%C3%BCtzt-TF-Karten/dp/B071147RGH?tag=thingiverse09-20">https://www.amazon.de/Cylewet-DFPlayer-Mini-MP3-Player-Modul-unterstützt-TF-Karten/dp/B071147RGH</a></p> <p>BOM for Arduino remote for eWall-E:</p> <p>Arduino Nano <a href="https://www.amazon.de/Elegoo-Entwicklerboard-Arduino-Atmega328P-CH340/dp/B0713ZRJLC/?tag=thingiverse09-20">https://www.amazon.de/Elegoo-Entwicklerboard-Arduino-Atmega328P-CH340/dp/B0713ZRJLC/</a></p> <p>Radio Module NRF24L01 <a href="https://www.amazon.de/AZDelivery-NRF24L01-Wireless-Arduino-Raspberry/dp/B06XJN417D/?tag=thingiverse09-20">https://www.amazon.de/AZDelivery-NRF24L01-Wireless-Arduino-Raspberry/dp/B06XJN417D/</a></p> <p>2x analog joysticks w/ push buttons -or- just push buttons</p> <p>2x pots for trimming speeds -or- none if you don't care for it</p> <p>4x push buttons -or- none for less function</p> <p>2x 3.7V rechargable batteries</p> <p>(unfortunately, I didn't have time to draw the schematics yet)</p> <p>--</p> <p>notes:</p> <ul> <li>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</li> <li>the tracks work with a redesigned 'slimmer' pin</li> </ul> <p>Arduino source code <a href="https://github.com/lmirel/eWall-E_r">https://github.com/lmirel/eWall-E_r</a></p> Category: Robotics
