Given that you posted this in the Inventor Subforum, I can tell you how to use a Design Accelerator for this. The advantage of Autodesk Inventor, in my opinion, is not the aesthetic advantage (which I'll admit I'm quite fond of) but the incorporation of Design Accelerators to help with fluidity in the design process. If you CAD the entire robot, don't worry about designing your own sprockets, bolts, chain, rivets- anything. Inventor will do it for you and give you calculations based on the size of the accelerator in your design.

For a riveted connection, you're best off opening your assembly and navigating to the "Design" tab in the Ribbon-bar. On the left side of the Ribbon, you'll find "Pin" , next to "Bolted Connection". When you click on pin, make sure you're set to cocentric (very important). Then, simply click the start plane, hole, and end-plane. You'll then need to select your rivet diameter. On the right side of the window, click on pin, and just choose the most appropriate one.

I advise that you save the rivet choice and diameter (bottom of the window).

Hope this was clear enough for you. Again, another option of course is to CAD the rivet manually and Insert constrain it into each and every hole. It all comes to a matter of personal preference.

Good Luck!
