In the last couple of days I have been working with the front nose for the robot. The front nose will have an integrated Intel Realsense ZR300 Camera. I want to integrate it to the nose because I want a seamless body. The Intel Realsense ZR300 is mounted in a aluminum housing originally and to be able to integrate it to the nose I need to disassemble the camera. The ZR300 have a stereoscopic depth-sensing camera integrated with robust motion-tracking capability, designed for long-range depth perception and position awareness, this development kit brings computer vision, position tracking, and object recognition to your prototype.
My first Nose Design came out pretty nice. I 3D printed the nose and was happy camper until i realized I had forgotten the USB port. As its turns out my design was to tight for the USB to fit.
The other thing I realized after playing around with the nose was that the camera should be mounted from the outside and not from the inside as I originally thought. Creating a housing within the nose itself and then reuse the cover material from the camera. Making the integration nicer and safer from dust and other things.
I started to design a new nose instead of trying to modify the old design. Usually it goes faster to do a new design. Ones started with this I realized that the USB space would act as a limit on the shape of the nose and the build surface of the Raise3D printer would limit the width of the nose. In this design the camera will be mounted from the outside and then attaching the original over the the PCB.
New nose design partly 3D printed. Testing the camera housing before printing the entire nose again. Came out pretty good need to make minor adjustments for USB. The housing was printed with PrimaSelect PETG solid White @225C and dialed back the Flowrate to 100 instead of 106 used with The PrimaSelect Black PETG.
So Before 3D printing a new nose again minor adjustment needs to be done to the new design. I need to mount the PCB 5-7mm deeper, so the USB head can fit nicely, other then that I think we are good. In the picture below I printed a camera housing and everything fits perfect.
To confirm the Field of View from the the ZR300 I did a quick assembly attaching the nose to the robot. Here is a short video on the field of view running ROS and RVIZ with a image and a depthcloud. enjoy!
