There isn't a "sleep" mode per se... Releasing servos will save power.... The ezb4 is pretty frugal anyway... with the camera attached it draws maybe 180mA.... You can always control the ezb4 with voice command because the computer is running the show and the ezb4 is always "listening"..... If you can use a larger capacity battery then that would be your best bet....

could the panic button be off use maybe?maybe as start Auto Position then wake up.

Use the Auto Release control: https://synthiam.com/Tutorials/Help.aspx?id=146

That will release the servos after a set amount of time not being used.

Once released, the ezb only draws 180 mha - which will last for over a day on a full charge with the provided lipo batteries. they'll drain quick as you use it, however.

thanks for replies everyone , new here and I do like those Tutorials ! Lots or really great features to put to use ....having a blast
