Lynx 6 stuttering and servo's appear to go off

For a project on school we have ordered a Lynx 6 robot, with only the SSC-32 interface working with RIOS software. Once we had assembled the robot we started testing it by the RIOS software, when we try to use for example the wrist, it looks like the elbow-servo losses power. And so the shoulder-servo suddenly stops when moving the elbow-servo.

Because we live in Europe we have replaced the 120, 60 Hz adapter by an external powersupply with 5 V and 2 A.

What can be our problem?

There are two issues.

  1. The servos work best at 6vdc. You can get even more power from the servos at 7.2vdc. There is a difference between providing 7.2vdc with a power supply and connecting a 7.2vdc battery. The 7.2vdc battery when fully charged can be almost 9vdc. So be careful.
  2. If powering the SSC-32 electronics (vl) from the same supply as the servos (vs), and using only 5vdc, the SSC-32 can reset if the power supply can’t deliver the required current. To eliminate this problem power the SSC-32 (vl) with a 9vdc battery and power the servos (vs) from a separate supply.

Hope this helps!

i had this problem in the past !
i was using a UNIROSS brand powersupply external adapter with a 3V to 7V output at 2500Ma
the problem was a bad contact between the adapter plug system and the plug system on the L6 (near the switch)…so, it cut power and rebranch randomly…and most often when the robot was moving because it move a bit the wires…i have solved that with a direct connection to the switch.
did you try to move the robot joint by joint with the SSC-32 module in RIOS ? try this while you are moving a bit the 5V adapter wires near the switch.
