We have a lot of milling to do today, so we zero the vice instead of each individual part. The Y axis is zeroed, then the X axis. Now we have (0,0) on on corner of the vice. We use a straight edge to line up material […]
We spend the first half of the day on the manual Acer mill roughing the outer dimensions of the eyelet plates. One of the skills we learn in the department is how to read a vernier caliper. The technology is old, but vernier tend to produce more consistent measurements than digital […]
We spend the day tapping the 8020 parts of our design. The monitor did not quiet meet our expectations of its dimensions. Luckily, we added extra space around the monitor, so this issue can be addressed. Speaking about the monitor, we had to mill the VESA mounting plate smaller […]
We’ve found two really great books on our topic in our amazing library (we have everything really, haptics is an obscure field). The first is Engineering Haptic Devices: a Beginner’s Guide for Engineers. Everything is broken down, the design criteria for the physical plant is laid out, making designing a haptic […]
We had the CAD review today. We gained valuable insight into tolerancing drawings and working with drawings from vendors. Here is a picture of our table. We were required to place the finished parts on top of the drawings for the inspection by the faculty.
A load of 30 pounds (133.4 N) was applied 5 times on a 1/32” wire found in the lab producing the results below. Assuming these random variations are in a Gaussian destitution, we are 95% confident that Young’s Modules is between 59758.2 MPa and 60299.1 MPa.
It seems someone has gotten labview to work with unity. This could make a good virtual environment wrapper for our project. [youtube]http://www.youtube.com/watch?v=Cf9blViDoG4[/youtube]
One of the major design challenges in a cable-suspended haptic interface is the creation of the spool. The spool must be designed in a way to prevent the line from piling up as demonstrated by this video at 34 seconds. [youtube]http://www.youtube.com/watch?v=uwgFkACxgWc[/youtube] Not only does the piling up cause the line […]
