Introduction


In the Robotics Software Engineering program at URJC, we've recently welcomed four iRobot® Create® 3 robots —an event that's certainly cause for celebration!— Given our intention to utilize these mounts for both educational and research purposes, we will frequently need to attach and detach various accessories as quickly as possible. Furthermore, these mounts must be as sturdy as possible while maintaining some flexibility for orientation.

We have a history of using similar mounts for a wide variety of sports and activities. Action camera mounts, standardized by GoPro®, appear to meet our requirements perfectly. Aditionally, design an interface for such a mount is easy enough to quickly iterate over different accessories like cameras, sensors, panels with AruCo markers… So here we are!

Certainly, employing an actual action camera seems appealing enough! It would serve as a valuable resource for both enjoyment and documentation purposes. 😬
 

Additional hardware

 

NOTE. The quantity of each component depends on the models and the number of them you will use. However, you will always need one of each for every hole in the model you are using.

  • Threaded inserts M3x4mm NOTE. Longer inserts will not work!
  • DIN7380 M3x6mm
  • DIN125 M3

As for the bolt securing the accesories to the mount itself, in the pictures I am using this model in its short version, along with one M5 nut (DIN1587)

 

Printing tips


I highly recommend using PETG for this application, as the clamping bolts will exert direct pressure on the weakest part of any FDM printed component. Layer adhesion is a crucial consideration here. While you have the freedom to choose any material you prefer, it's essential to keep a close watch on this aspect.

Regarding the printing settings, feel free to select those with which you are most comfortable. However, bear in mind that since the final assembly involves additional hardware, the tolerances of your part will also play a significant role.

If you are utilizing PETG, please adhere to the original orientation. The holes designed for the threaded inserts are sufficiently small to be printed without supports; thus, their usage is unnecessary.

 

Assembly

 

  1. Insert the threaded inserts in the holes of your mount, using this guide as a reference.
  2. Use the numbers of bolts (DIN7380) needed along with the same number of washers to firmly attach the mount to the faceplate of the robot.
    • VERY IMPORTANT NOTE. There are several models available, two of them (Standard_Mount and Flat_Mount) are intented to be secured anywhere in the faceplate, with bolts or tape, respectively. However, there are eight more models intented to be secured at the very edge of the faceplate. You can use this image as a guide:

  3. Optional. If you have already printed the thumb bolt, you can now secure it to the mount. There is another model called Disk, which is intented to be decorative as long as there is not anything mounted.
  4. Take some pics and upload your result! 😄
  5. Done!

 

Hope you find it useful. Cheers!

Model origin

The author remixed this model.

Differences of the remix compared to the original

The model has been modified to accommodate an interface that is compatible with different positions on the faceplate of the iRobot® Create® 3.
