Using the TCRT5000 Photo Reflective Sensor as a Line Following Sensor

In this video we are looking at how to use the TCRT5000 photo reflective sensor for line following.  Line following will be utilized by the Zoomie for guidance during all straight line driving.  We will cover the many aspects of the sensor including how I tested the sensors analog output over a variety of different line types.  

PICO / Micropython specific discussions include:

  • Measuring read time of the sensor
  • Writing testing reading to a file inside the PICO
  • Graphing the analog readings to "see" the line transition



Cheers!

Constructing Powertrain Deck for the PICO Controlled Autonomous Robotic Car

The Powertrain Deck is a critical element for the Zoomie, the autonomous robot used in the ZoomTown experiment.  Chris explains the 'what' and 'why' of this subassembly and how it is the foundation for the rest of the Zoomie.

Cheers!

Motor Drive Selection for the Autonomous Robot used in the ZoomTown Experiment

 Selecting a motor drive for the N20 motors didn't require a lot of research.  In this video Chris explains why the TB6612FNG was a good choice based on the defined criteria for the autonomous robot.

Motor selection for the Autonomous Robot used in the ZoomTown Experiment

Selecting a motor for the Zoomie is harder than ever with so many choices! As already covered a few episodes back, the design criteria for the Zoomie is pretty well defined.  In this video Chris talks through the choices and the reason why some are good and some are bad.  

Cheers!

A FAILURE ALREADY? Zoomie V1 is a failure.

This experimental robotic car failed in the prototype stage.  The design was certainly unique so it was worth the time to explore and experiment.   However, some designs are best left in the prototype stage, this video explains why it failed and more importantly, what was learned along the way.



Cheers!

The ZoomTown experiment has reached a fork in the road, what to do?

The results of the most recent test involving test trips have been very disappointing and extremely discouraging.  This episode discusses th...
