3D printed components for a 1WD Robot managed by a Arduino UNO microcontroller

Aktualizacja u źródła: 5 kwi 2025

Informacje o modelu

A set of printed components to build a 1WD Robot that is controlled and managed by a Arduino UNO microcontroller and a UNO motor shield.

This (now quite old!) robot development can be controlled with a pair of slide switches.

All the components use 1.75mm PLA and a layer height of 0.15mm with print details for each component produced on an i3 Mk3 shown in the table below.

Further details on the build and use of the robot are at this link and example software to operate the robot is downloadable from here.

component file name/description	needs support (Y/N)	brim (mm)	filament length (m)	print time (i3 Mk3)
