Hi,
I've been through the tutorial on facial recognition. Two issues:
1) I'm getting 'false positives.' Roli see's my face and moves (Enable Movement Tracking is checked) Works great. When I'm not seen by the camera, he often responds. What setting is off? I've adjusted the grid & changed rooms assuming lighting could be an issue.
2) I'd like Roli to watch me as Omnibot does with DJ Sures's tutorial video. I checked servo Tracking but there's no response. I can see the square around my face so obviously the camera sees me.
I guessed that it might have something to do with the ports. On the configuration screen, I selected ports 9 & 10 (horizontal & vertical) but still no response.
Any suggestions are appreciated. Thanks in advance.

Add more light
Servo movement - check the grid. Only if that yellow box isn't in the centre square will it move. Also double check the ports, the options (inverted movement etc.) and that servo tracking is enabled. Relative tracking needs to be disabled for Roli in his/her intended configuration.
Only Facial tracking is checked. The x servo is port D9 and the y servo is D10. Enable Movement tracking is deselected. Track by Relative Position is selected. I only want Roli's head to move as I move.
I also tried different rooms to see if lighting was an issue. Still no response.
Just to confirm, Facial tracking works when Enable Movement Tracking is selected.
It doesn't seem like the signal is reaching the servos when Track by Relative Position is checked (Enable Movement Tracking and Enable servo Tracking are deselected.)
I've attached a screen shot of the configuration window. Are the settings as they should be?
Yes, I discovered that poor lighting and clutter in the room results in false positives. So that's cleared up. Thanks.

Rich mentioned that Reletive needs to be disabled and servo tracking should be enabled. Looking at your picture, you still have "Reletive tracking" enabled and "Servo tracking" is disabled. Have you tried it the way Rich mentioned?

So to confirm - servo Tracking is enabled and there's no response.
Track By Relative Position - Disabled
Also, change the max and min values of the X and Y servos, both are set to 90 so the servo can't move.
If it's Roli, open the example Roli project and check out the controls.
Everyone else, thank you. I am a newbie to this and finding it difficult to connect all of the dots.
