Hey guys, so my son and I are having a great time with our little "rolli" robot. Yesterday, we decided to start experimenting with the tracking feature. We've watched all of the related tutorials we can find, and it seems like a pretty strait forward thing, but we cannot get our little guy to track. When we enable servo tracking, and use any of the tracking types (object, color, multi-color, etc) The camera slowly drops off to the lower left until the min/max settings are hit. The little blue box is around the object and seems to be correct, same thing every time. When we enable movement tracking, it charges right at the object. It attacks more than tracks. Same deal though, purple box present and accounted for, right as it plows into what its supposed to be tracking. Any ideas? blush
Did you view the camera control or the tracking activity? There are question marks on the controls to access their respective help pages. The activities can be found in the learn section. Here are some direct links for ya!
First I recommend reading what the options do. And understanding that hovering over the blue question marks gives you help: https://synthiam.com/Tutorials/Help.aspx?id=80
Also, check the bottom of that link for tutorials related to the camera.
Second, here's an activity: https://synthiam.com/Tutorials/Lesson/59?courseId=6
Learn section is your friend. Even better, the blue question marks and question marks on the controls next to the close button are important
.
Let me know if you need more assistance.
It also helps to use 1 tracking type at a time, and learn and understand how it works, before adding another type. When you just click all the check boxes it's all just a blur of functions...I get lost as to what's working.
Doombot, We have been using just one tracking type at a time. We've gone through each, one at a time, hoping for better results with each different tracking type.
DJ, thank you for the links.
We've read/watched both of those already (a few times) and several other pages. The little blue question marks are very helpful, and believe me- not ignored, but they only explain what things should do, or are supposed to do.
When we "learn" a new object, or "edit" a custom color, etc. everything goes as shown in the tutorial, until the point when we go to tracking and click "object" or "multi-color". The camera appears to recognized our object or color, but instead of keeping it in the center (or somewhere close) of the grid lines, the little guy just drops his head like he's ashamed. The blue/purple box around our object/color just slowly moves off screen through the upper right hand corner. tired
We'll keep trying. I'm sure we're just over looking something. I welcome any other suggestions.
I suspect you may have the pan(rotation) and tilt(lever) camera servo wires plugged into each other's ports. If they are reversed, the symptom you are seeing is exactly what you would get.
As for the "attack" vs follow, there is a setting for the size of the object when tracking. I don't have the instructions in front of me since I am at work, but in one of the tutorials it covers how to have it follow without getting too close by setting this parameter.

Sounds like either your pan/ tilt is wired the wrong way or you need to enable servo reversing on one or both servos. Try and use one servo at a time, say horizontal ( left/ right). Get that tracking first and then try adding in tilt.
Thanks guys! We did have the pan/tilt assigned wrong in the servo tracking (x/y), I reassigned the ports and now this little guy is tracking perfectly. Now we're going to tackle it with the movement tracking option selected. But, first we're headed to find the tutorial explaining size of the object. Thanks so much for the help!
:D Awesome! And that's how it's done - nothing more rewarding than feeling accomplished
