Bluetooth Mini Track Loader

thingiverse

Great news! I've just completed designing and printing a very cool charge adapter for the track loader. It'll be available within the next couple of days. You can find the Charger here: https://www.thingiverse.com/thing:2794970. I'm still working on this project, and more files will come. More description will come too. This is my take on the Mini Track Loader. Instead of using an RC Remote, I wanted something that would be more easy and lightweight to bring along with me on a daily basis. So, I redesigned the body to get more space inside for a Arduino Pro Mini, a Bluetooth module, a small 1s lipo battery, an on/off switch, and a charging plug - plus a little extra. You can watch a video of it here: https://youtu.be/NIg1I9ntlLo. This Track loader is based on the files from @lijingwei. Lijingwei writes: "This is a bigger track load using 9gram servo. All parts are all redrawn based on Zedpi's Mini Track Loader RC. The Lego track is no more supported, you have to print track with flex material. The servo I'm using is emax es08ma - other similar 9gram servo should be okay but not tested." To build this project, you'll need the following parts: 1x Arduino Pro Mini (https://goo.gl/D2z6b4) 1x Bluetooth Module (https://goo.gl/hRQhzv) 3x SG9 servos (https://goo.gl/fRvFBf) 1x On/Off switch (https://goo.gl/78AyvA) 1x 1s Lipo 180mAh (https://goo.gl/Hp6TaL) 1x 2 pin SH size connectors (https://goo.gl/r2ni9r) Optional parts include: 1x FTDI USB Adaptor (https://goo.gl/Tt3dWA) 1x Mini buzzer 5v (https://goo.gl/62NGMi) 1x Yellow 5mm LED PAD-11 Crimp Tool (https://goo.gl/U5KtBk) UPDATE 2018.01.15: The android app used to control the track loader is made by Andi.Co and can be found on Google Play Store. You can find it here: https://play.google.com/store/apps/details?id=braulio.calle.bluetoothRCcontroller. UPDATE 2018.01.17: The Arduino code is now uploaded, and it's a very modified version of the one made by Andi.Co. UPDATE 2018.01.21: Schematic is done and added as a picture in the Post-Printing section. UPDATE 2018.01.22: Description for modifying the belt servos has been added to the Post-Printing section. UPDATE 2018.02.09: Files have been updated - I made some mistakes with the wheels and track files. Now, you'll have two options: Big track or Lego track, with four files for each, clearly marked.
