Course Objectives

The goal of the course is to familiarize the students with the concepts

and techniques in robotic engineering, manipulator kinematics, dynamics and control, chose, and incorporate robotic technology in engineering systems.

• Make the students acquainted with the theoretical aspects of Robotics
• Enable the students to acquire practical experience in the field of Robotics through design projects and case studies.
• Make the students to understand the importance of robots in various fields of engineering.
• Expose the students to various robots and their operational details. Course outcomes: After this completion of this course, the student should be able to
• Understand the basic components of robots.
• Differentiate types of robots and robot grippers.
• Model forward and inverse kinematics of robot manipulators.
• Analyze forces in links and joints of a robot.
• Programme a robot to perform tasks in industrial applications.
• Design intelligent robots using sensors.
