037 The Ever Evolving Zoomie and Viewer Suggestions

Рет қаралды 282

Күн бұрын

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.

Wow, Steves QR Code suggestion is really fascinating! Impressive cross-thinking :)

I love the idea of using an e-ink display to give changeable information to the zoomie. There are 1 inch x 1/2 inch modules available but it could get expensive.

I love the idea of E-Ink too, but like you said, could get expensive. I am anxious to get testing on this, if for nothing else, just to see that little sensor work and what it is capable of - SO MUCH POTENTIAL!!! Cheers! Chris

The QR codes is a good idea, you may want to look into magnet sensors or compass sensors so as it passes a location, it knows what direction it is facing to " expect " the next QR code. The software can then compensate for travel time for the distance when the drive batteries go low. I do not have a link for the sensors, you may want to have it mounted on the top of the Zoomie to prevent EMF interference from the rest of the electronics. As to the tinning of copper, you can still find " tinning solution " and cheap paint brushes to brush on the tinning solution where you want to solder. I had a bottle from years ago and had to keep adding small amounts of water to it before use due to how long between uses and how little I did use. The paint brushes should be thrown in to proper disposal as they will have traces of toxic chemicals on them.

Thanks for sharing all that information! Magnets are being used in conjunction with the TCRT5000 sensors to help with localization - working pretty good. Yeah, I have the liquid tin and use it but still not as good as the real thing - especially when you have a lot of soldering to do. Digital compass will not work at all in this location - I have tried many of them a few years back on another robot project. There are two very strong sources of magnetism in this space and both of them are stronger than the earth's pull. It certainly would help to make this project easier of it would work! Cheers! Chris

Chris, I pick up Steve's idea and put it a little further ... The QR code could deliver even more information. For example: "slow down, curve ahead. curvature will be x" "parking lot to the right" "slow down, stop sign ahead" That way, the zoom could be proactive instead of just reacting. Maybe this great advantage is worth prolonging your loop cycle up to 10ms. Also, to push it eben more: instead of putting QR Code labels on your track, why not build-in small monochrome e-ink displays? That way you could also direct your traffic and stuff :) Enough said, enjoy your pizza tonight! 🍕🍕🍕

Wow, some serious add-ons to Steve's suggestion. There is a lot of potential with this concept. I have a couple on order and should get them early next week. It is probably going to take some serious work to get it working with the PICO W and MicroPython, but I am curious to see what can be done. The Pizza was great as usual !!!! Been eating any more of the super hot foods???? Cheers! Chris

Well I am excited and really looking forward to your findings and presentation! Naaaa, we don't go there too often so the taste does not become "usual" and stays an excitement :)

@@tomek3633 LOL! I get that, some things just need to stay "Special" so there is something to look forward to! Cheers! Chris BTW - just posted a new video (and it is a SHORTY)
