Hello,



I'm creating a 7 DOF robotic arm with XM430-W350 as the first two motors, XC430-W240 as the next three motors, and XL330-M288-T as the last two motors. I'm using an Arduino Mega 2560 with the Dynamixel Shield. The specs for the motors for the input voltage are as follows:

XM430-W350: 10.0 ~ 14.8 [V] (Recommended : 12.0 [V])

XC430-W240: 6.5 ~ 14.8 [V] (Recommended : 12.0 [V])

XL330-M288-T: 3.7 ~ 6.0 [V] (Recommended : 5.0 [V])

Since the Dynamixel Shield comes from one power supply, how can I make sure all the motors have enough voltage to power all of them?


Thanks!

Hi,


If you are using two different voltage source in a single system, you should separate the power source accordingly.

Without an additional voltage regulator from 12V -> 5V, it will be difficult to use XL330 along with other 12V DYNAMIXEL.

Thank you.

Thank you for your response!
How can I hook up two different voltage sources in one dynamixel shield? Or is it possible to stack the shields with one using 12V and the other using 5V?

DYNAMIXEL Shield does not support two different power source inputs. You'll need to use an external voltage regulator to provide a separate power to XL330.
Stacking up the DYNAMIXEL Shield is not recommended as DYNAMIXEL connected to each shield will be considered as a separate communication channel.
