  2. Press the Project tab from the top menu bar in ARC.
  3. Press Add Robot Skill from the button ribbon bar in ARC.
  4. Choose the Navigation category tab.
  5. Press the Kinect Xbox 360 Depth Mapping icon to add the robot skill to your project.

How to use the Kinect Xbox 360 Depth Mapping robot skill

Use the microsoft xbox 360 connect to send navigation/obstacle information into the ARC NMS (navigation messaging system). This skill publishes obstacle scan distance data to ARC's NMS (navigation messaging system) to be used in SLAM or The Navigator skills.

Because the entire image depth is unnecessary to be processed for mapping, only a portion is. This prevents your robot from picking up distances of things irrelevant to its size and distance. Using the options for the detection area, tune the pink box to the area of detection.

Required Drivers

The SDK 1.8 can be installed from here, as you will need the libraries it includes:

*Note: under development (see To Do)

User-inserted image

To Do
- additional testing to verify distance from point cloud is calculated correctly
- compensate for distance with camera angle
- add variables (min, max depth & sound direction)
- move detect rectangle into config menu


Upgrade to ARC Pro

Harnessing the power of ARC Pro, your robot can be more than just a simple automated machine.

Nice! Must get me a Kinect.
So far my test results aren’t that great. I think the intel depth camera is the way to go ... or a 360 degree lidar
Yes, the lidar seems to be the logic choice with the T265. It way less recourse hungry.

Still waiting for my T265............
That t265 is super great. Wish they were cheaper and more of them lol
I'm very interested in this skill!

I really like the idea of using Kinect sensors on robots because you can find them for pretty cheap these days. They are usually around $10-15 CAD at second-hand stores and sites.

In the future will this skill be able to move the Kinect pan/tilt motors?

Has anyone tried powering the Kinect's 12V line with a lower voltage? like 11.1V?

There’s no advantage to moving the motors, if they exist in the model. It would decrease the accuracy of detected obstacles degrees/distance by the Kinect
I don't have a kinect, but would love to see this skill in action. A video about it would be great.

@DJ I have to disagree with you, having the pan/tilt would be highly advantageous!

You could map at different vertical levels or do mapping while in a stationary position. Say you have a robot that doesn’t move geographically (like an arm) but the environment changes around it, it would be very helpful to do a quick scan within the range of the Kinect sensor

The onboard motors can also help with the camera view itself (excluding the IR depth sensing). I would much rather use the motors inside the Kinect to look around instead of having to install my own servos. 

Lastly, you could use the motors are they were originally intended as well! Use them for human body scanning with the Kinect Body Control skill.
Again, there's no way to identify the degrees for the NMS. Please read how the NMS works and there's some additional reading about the accuracy of angles for correct pose navigation.
I thought I was in a 70's disco. Think my kinect is really badly calibrated. Maybe needs a calabration checkerboard routine.
The Kinect has no calibration - as it’s a camera. And the camera has a lens. And the camera has a resolution. And that pixel resolution with the lens angle gives you angles of distances in degrees. 

it’s not great for mapping, as you probably just discovered. What you’re experiencing are why these technologies are often abandoned for robotics. New technologies are being made to replace this old stuff. 

the intel depth camera I think will be good. They have a lidar too. Might have to check those out one day

Nicolos Burrus had written some code to software calibrate the kinect with a checkerboard map to align the  speckled laser depth image and camera, when you get it right it creates a fairly good 3D Slam. looks like latest versions do auto calibration been years since I played with a kinect   
Hmm you have to cut and paste url or change https to http, looks like it changes to https when you click on it
Hmmm - I think that's for the first-generation Kinect, not the box 360 version
I know primesense had sold their chip in a number of devices (Asus xtion, eyeplay etc) but from a "Kinect" standpoint the XBOX 360 had the first Kinect version.
