I just ordered a SES Arm from USA to Sweden.
I’ve assambled it and noticed when I’m trying to run all the servos the arm goes “limb”…
when i’ve started the shoulder, elbow and then try to start the grip… the Arm loses it’s power for the shoulder and elbow…
but the grip works. Im trying to go back and enable them again…
but with no succes… they can’t all work at the same time.
Then i tryied to (Im using the standard power adapter DV 6V 2A) connect a external power supply and still have
the standard power adapter connected… It worked (had the voltage steady at 6.34V).
So it seems that the standard adapter doesent deliver enough power. Maybe it works in USA… but seems not to work properly with europeen standard? Or I’m wrong?
That was problem no2.
The first problem i had was that the HS-475HB (wrist up/down) did’nt work. I’ve connected other the other servos to pin 3 just to rule out that it were’nt something wrong there.
We are using the same 6vdc 2amp wall supply for the L5 L6 and the SES arm. The supply works well for the L5 and L6, but the SES arm may draw too much current. There are several things that can effect this, but the solution is easy. Just remove the VS1=VL jumper, and install the 9vdc battery clip on the VL terminals. This will prevent the servo voltage dips from effecting the microcontroller.
