MoSeq Cage

Step 1

Set up all your brackets with nuts and bolts like this:

Note: the orientation of the nut is crucial! Please be sure the lip of the nut is facing exactly as is shown:

Step 2

Make 4 right angles with one short 19.5" (49.5cm) beam and one long beam, like this:

Note: The best way to secure the corner bracket to the 80/20 is by sliding it in like this:

Note: Orientation of the nut when sliding the bracket into the 80/20:

Step 3: The Bottom

After four independent right angles are made, it's time to join them. Attach a second bracket to your long beams like this, making sure to have the beam and empty bracket in the same location on each corner:

Then, make the bottom:

Step 4: The Top

Now assemble the top portion of the cage, which will slide right into the bottom portion from Step 3 and eventually hold the Kinect.

First, make two of these with 19.5" (49.5cm) beams:

Then, slide four inside corner brackets into those beams (these tighten with a 1/8" hex wrench):

Next, assemble the tube bracket -- this will hold a tube that the Kinect will be secured to. Slide two nuts (80/20 part #3202) into an 18.5" (47cm) 80/20 beam, then secure the bracket to the beam:

Finally, assemble the top...ON THE FLOOR! You will be sliding the inside corner brackets around in multiple directions; floor assembly makes things much easier:

NOTE: Make sure to adjust the inside-corner brackets to leave a 0.5" gap on both sides of the 18.5" (47cm) bars. The top will not fit on the rig otherwise.

Step 5: Top + Bottom

After securing bolts so that no beams are sliding around, slide the top into the bottom (now a good time to phone a friend for assistance):

[CRITICAL] Note: The recommended height for Kinect video acquisition is 26.5" (67.3cm) from the Kinect sensor to the bottom of the apparatus.

Attach the tube to another tube bracket:

Now, connect the Kinect with a single 1/4-20 screw:

Done!

It is critical that the Kinect2 depth camera is 67.3 ± 0.5 cm to the bucket floor to ensure the acquisition quality. The mouse would be too small when the depth camera is too high and part of the mouse will be cropped out because the part exceeds the minimum depth threshold of the camera.

You can verify the camera height after installing the acquisition software.
