19 .Chain Alignment • Important aspect of design is the motor alignment of chains, gears or pulleys. • This relates also to cams and fourbars. 

20 .Supporting Shafts motor 

21 . Building a Robot Supporting Shafts motor Shafts must be well-supported! 

22 . Building a Robot Supporting Shafts motor • This is a really bad design. • Many early designs from this class were like this, although I told students not to do this.
