Arduino Zero Timer / PWM Direct Access Notes

If you want to access the timer or PWM outputs more direct style here are some helpful links: Link to google docs explaining the PWM pins and their associated timers used on V1.0 of our microbot PCB    Arduino forum example library code to set PWM values manually – Includes TC3 code which most examples

Microbot 2016 Software/Firmware Setup

Microbot Mechanical Design Guide

Wheels: Outer Diameter: 10.6mm Thickness: 2mm O-ring groove diameter: 1.8mm O-ring groove inner diameter: 9mm Center mounting hole:  2mm diameter – ideally with .5mm D cut or wheel may spin on shaft Chassis:  Starting Body Extrusion: 19mm width, 23.5mm length, 16mm height Top Cutout subtraction: 17mm width, 21.5mm length, 8mm height – this should leave you with 1mm

3D printer computer upgrades

We have a new laptop to run the 3D printer which replaces a 10 year old desktop computer that was on its last legs. Printing a test boat model here to make sure the software transition worked properly.

Timing Belt Design Information

Timing belts can be great at moving power around, and changing speed/torque from source to destination. They can also be tricky to work with. The standard belt size used on FIRST robots is 5M-HTD 15mm wide belt The_World_of_Timing_Belts – This design guide from Gates is very helpful. Some Suppliers: http://polybelt.com /    

Using the 3D Printer

Prepare   Software Design: Autodesk Inventor 2015 Student Edition – download and install on your computer or use one of the schools computers Print/Slice: Slimplify3D – Already installed on the 3D printer dedicated computer, not necessary to have on your computer Process File Download (sets basic printer configuration): Process Print Import your .stl file into simplify3d
