KinematicsKinematics Kinematics is the study of motion without regard for
the forces that cause it.
It refers to all time-based and geometrical properties of motion.
It ignores concepts such as torque, force, mass, energy, and inertia.

Advantages And Disadvantages Advantages And Disadvantages
Robots increase productivity, safety, efficiency, quality, and consistency of products.
Robots can work in hazardous environments without the need.
Robots need no environmental comfort. Robots work continuously without experiencing fatigue of
problem. Robots have repeatable precision at all times. Robots can be much more accurate than human. Robots replace human workers creating economic
problems. Robots can process multiple stimuli or tasks
simultaneously.
Robots lack capability to respond in emergencies. Robots, although superior in certain senses, have limited
capabilities in Degree of freedom, Dexterity, Sensors, Vision system, real time response.
Robots are costly, due to Initial cost of equipment, Installation costs, Need for Peripherals, Need for training, Need for programming.

•Emotionless Machines
•Cannot logically reason, and/or plan activities, unless the designer program it to do so.
