Dynamixel XL320 and vision
2018-01-13 06:34:13 Espen


I want to build a robot arm with some pick vision.

There will be a robot arm with the XL320 servos and a camera for object detection.

Which board/setup will you recommend for this and will handle this?

I'm hoping to not use several boards; just one board for servo control and for the camera/vision processing.

Hello Espen,

I apologize for the late response.

If you wish to perform the vision algorithm, you might want to use something like Raspberry Pi Zero W(wireless & Bluetooth included).

But it will not give you an abundant processing power.

I think you need to search for more examples for image processing as the performance required is diverse based on the size of image, processing frequency and applied algorithms.

Also, you will need to have an additional device or board for communicating with XL320.

I do have a Raspberry Pi 3 that can use. Is RPi better than an Arduino for this? I'm open for both. Arduino is maybe easier since it is pretty similar?

So I could go for the RPi 3 that I have and use the USB2Dynamixel for communication to the OpenCM9.04, and thats it?

Can you recommend a setup for the RPi and Arduino?

I'm now thinking of using my RPi with the U2D2 adapter, SMPS2Dynamixel (+power supply) and 4 XL-320. Is there one off these that is not compatible with the XL-320?

I apologize for the late reply.

Recommended input voltage for XL-320 is 7.4V which is a series of two Li-io battery cells.

SMPS2Dynamixel will supply 12V and it will be too much for XL-320.

You might need to regulate the input voltage to 7.4V.
