040 Can a Vision System be Used as a "GPS" system?

In this video we explore the idea of using vision tracking to keep track of where all the Zoomies (Robotic cars) are located. There will be up to 16 Zoomies moving about ZoomTown at any given time, each Zoomie will need to have knowledge of the other Zoomie's locations. For example, when backing out of a driveway, the Zoomie will need to know about the cross traffic.

Cheers! Chris

039 Can a QR Code Reader Help with Robot Localization?

 Based on viewer feedback, we are taking a look at the Tiny Code Reader from Useful Sensors for the purpose of helping with localization.  Keeping track of where the Zoomie is within ZoomTown is critical as it is with most robotic applications.  We will explore a lot of the details on how this sensor can help with localization.  

Cheers!

38 Achieving Robust Line Following and Position Tracking

The Zoomie has moved up a notch on performance!  The line following is very robust, so much so, I can push it nearly 45 degrees off course and it easily corrects course and continues on.

Position tracking (localization) has improved significantly using the hybrid system of the AS5600 encoders, TCRT5000 photo reflective sensors, and some A3141 Hall effect sensors.  This new method is bringing the project very close to 1mm accuracy!

Cheers!

037 The Ever Evolving Zoomie and Viewer Suggestions

 In this video we will discuss some viewer suggestions and the evolution of the Zoomie.  With these new suggestions, will the Zoomie evolve again?

One suggestion has to do with the mechanical design of the Zoomie and how it could be modified to turn more accurately.

The other suggestion is a sensor that can read markings which would be very useful for localization.

036 New Concept for Position Tracking

 Localization is difficult, especially when using simple sensors, in this video we will discuss a new concept that combines using: PICO W, Wheel encoders, Photo reflective sensors, Hall effect sensors, and some creative markings to achieve better localization.

Cheers!

Initial testing shows promise for Hybrid encoder concept

This past weekend (6/22/2024 and 6/23/2024) I was able to work in the development  and testing of the new Hybrid concept of combined ABSolute encoder markings and the ABSolute motor encoders we have been using.   The photo below shows Test Track Z with some of the modifications.  

There is still a lot more work to do to get this refined though.  I still don't think I will achieve 1mm resolution, but it is very close most of the time!!!!

While going through this process, I thought of an idea for a story showing my method of development and testing that I use (especially in my older years).  I think this may be of value to you so hopefully I have time to get that produced for you.

Cheers!
