ENGR 2120: Dynamics

 roject Assignment

For  this  project,  you  will  re

-visit  the  robotic  welder  that  was  analyzed  previously

.   Instead  of  

performing  the  position,  velocity,  and  acceleration  analysis  in  Cartesian  Coordinates,  you  will  

repeat  this  analysis  using  normal  and  tangential  and  polar  coordinate. 

This  will  allow  you  to  

compare and contrast different coordinate systems and allow you to determine which one is be

st 

for this type of application. As you will see, the choice of coordinate system can drastically change 

the complexity of the problem at hand!
