Like most guys, I enjoy keeping up with technology and having the latest “toys”. I’m still a student in college and am going into engineering so I’m always curious of the parts that it takes to put my gadgets together. Many people just buy, buy, buy without knowing how their toys are made or the work it takes to make such things. During one of my classes I had a huge project where I had to work with robotics.
I had never worked with robotics and thought it was going to be much more difficult than it actually was. If it wasn’t for ball splines I would have never made it through my project. Ball splines are a special type of linear motion bearing that provides linear friction-less linear motion and also transmits torque. The difference between a shaft and a bushing is that a shaft is free to move up and down and is free to rotate.
