Flexible Robotic Arm
It is possible to make high speed and light weight manipulators for complex robotic assembly tasks and remotely operated space programs has motivated research work in the field of dynamic modeling and control. A kinematic and dynamic model of serial link manipulators with flexible links and joints has been developed. The flexibility is represented by decomposition of the deformations on modal basis for each of the links.
What you think guys !!!
I agree because there are a lot of places where we require robots with dynamic control. Its not like robots are only used for stiff purpose jobs only like lifting something from one places and putting it somewhere else. In many of the industries such as the manufacturing ones, robots with flexible links are used in order to help with the packaging process. We can understand this with a single example, suppose a robot is used for lifting a cup, now if we are using a robot with stiff and less joints, then it'll have a hard time to pick that cup if the position is changed and kept in a place with some obstacle, the same way if we are trying to lift the cup using a flexible arm, it becomes really easy since thanks to its flexible links and too many joints, it doesn't faces any problems while bending and going through the obstacle. So we can say that flexible arms are a lot useful in many robots.
