Precision couplings

admin 2.77, 2.77 Seek and Geek Leave a Comment

In one of my research meetings with my advisor, Prof. David Trumper, we were discussing about motors and motor couplings. He mentioned about how the metal bellows for precision couplings are manufactured using electroforming process. I did some more search on the topic, and found that they are very useful torque transmission elements which are very rigid torsionally and accommodate misalignments in …

How are ball bearings made?

When I was making the Kinematic Coupling for Lab-4, I was wondering how I would manufacture the wooden balls. In the first day of class, Prof. Slocum had given us a wooden hemisphere which looked almost perfect. The most number of balls that are used anywhere in the world is in ball bearings. They are mostly made out of steel, but …

Seek and Geek – 2: Robots to manipulate work-volumes at a large distance from location of base actuators

admin 2.77, 2.77 Seek and Geek, Uncategorized Leave a Comment

In my project, I’m trying to build a cell-sorter, primarily focussed on picking and sorting of islets. One of the major constraints in the design are that the work are is under the objective lens of the microscope. Thus all actuators should be outside this field area, yet resulting in motion accuracy of ~ 25 um. The are two major …
