I am working on InMoov hand project. The Software will disconnected the EZ-B 4/2 when I add more than 1 servo Motor.
Can anyone tell me the solution? Thanks.

You're starving your servos. They need a bigger power supply with the capacity to supply more current.
*edit: now I have the little shop of horrors theme song in my head
I'm using an adjustable voltage BIC's produced by Castle Creations for the different voltage needs of servos on my B9's arms. The BIC's are rated at 10 amps each and are switching style. Kinda expensive at $22 UDS each but I absolutely love them. They're tiny, very light weight and run cool. You can have a higher voltage power supply like 12vdc (rated above your amperage needs) and use these tiny BIC's to step down the voltage in .5 volt steps to what ever voltage you want. You program the wanted voltage through your computer. Here's a link to a lot of info on this BIC:

You can get them on AMazon for around $25 USD each here:
Amazon CC 10 amp Bic's
Unfortunately you'll also have to buy one of CASTLE LINK's USB PROGRAMMING KITs to set the proper voltage. The BIC's come from the factory set at 5.1 vdc. They cost about $20 USD. The Software is free. Read about them and buy here:

After stepping down the voltage from 12vdc to 6 or 7vdc as needed they easily handle the amp draw of my power hungry servos lifting up to 4 pounds while thay are moving fast.
Good luck and have fun!
Probably feels cool - like a mad scientist. Inventing in a lab
You are all right, thanks to cem, Dave Schulpius and DJ Sures.
Cem, Right! i completely forgot about requirement of voltage of servo. thanks for remind me.
Dave, Thanks for your information sharing. I seem, I need to change switching power supply to convert AC to DC 12 v. for the 1st step, then regulated DC to DC (12 v. to 7.4 v). If I had understood.
DJ Sures, thanks for sharing idea and developing interesting Hardware and Software. I do hope to control more activities with your reliable micro-controller EZ-B V4/2 than MRL software. Looking forward to your cool product development!!!
Very nice work you do
