PACERBOT Parts 8 – 11: Custom Optical Encoder

25 05 2016

Measuring speed can be done in many ways. I chose to build an optical encoder, to  sense the frequency of the drive shaft’s revolutions, and calculate the speed by recording the time between pings.

PACERBOT Part 4 + 5

21 05 2016

The design,printing and assembly process of the resting place for the battery. A rectangular box that seats on top of the transmission serves as a holder for the Arduino board in addition to a battery holder. A straightforward, though important part of the robot.





PACERBOT – Part 3

A more specific overview of the robot. Showing the various components in more detail. Read the rest of this entry »





PACERBOT – Introduction

15 05 2016

Hi, I’m glad to finally share with you a project that I began about four months ago. The PACERBOT! An Arduino Uno based robot designed to pace track runners and perform as a physical guide. I will post brief summaries of my progress along the way, besides more detailed video logs.
