Track Vehicle System

Track Vehicle System3D-printed track vehicle system with batteries and motor built into the tracks.General infoThe leading idea behind the project was to create a tracked vehicle system "in the comfort of one's home", with readily-available parts and on an inexpensive printer.Other milestone in the making of the project was to embed the motor and gearbox system, as well as the batteries, directly into the tracks.HardwareThe motor is specified to run at 12600 RPM, and it's attached to a 100:1 gearbox system. Alongside of it, 6 pieces of 18650 cells in 3S2P arrangement are embedded into the track system.For the minimal version, an ESP32 device was connected to a relay array which control the power switching, as well as the direction the motor is turning to.Another ESP32 device is setup to send joystick commands to the first ESP32 chip via ESP-NOW communication protocol.Various screws, threaded rods, and nuts and bolts were used, with some of the parts such as bearings or nuts also being printed.PrintingPrinting was mostly done with 0.6mm nozzle, with an exception on the gearbox system printing where greater accuracy (0.4mm nozzle) was required. Material selection followed a similar process, where PLA was used for most of the print, with HIPS or PETG being used for the gearbox.Complete print takes around 200 hours of time and 4kgs of plastic.3rd-party works and authorsBelow is a list of works which were used in the making of the project.Maxstone Crawler Tank Tracks by evil_k100:1 Compound Planetary Gear Reducer by Gear_Down_For_WhatPrint in place bearings by Jerryie
