Degrees of Freedom in Mechanics

“Degrees of Freedom in Mechanics” is a crucial read for anyone immersed in the world of robotics, mechanics, and engineering. This book takes a deep dive into the fundamental concepts of mechanical freedom and constraint, addressing essential topics from basic kinematics to advanced manipulator systems. Authored by Fouad Sabry, this volume is a musthave for professionals, students, and enthusiasts seeking to understand the mechanics of robotic systems, both in theory and practical application.

1: Degrees of freedom (mechanics): This chapter introduces the concept of degrees of freedom, explaining its significance in mechanical systems and how it influences the motion of objects.

2: Machine: Explore the nature of machines, including their structure, function, and the role of degrees of freedom in determining machine behavior and capabilities.

3: Kinematics: Learn the principles of kinematics, focusing on the motion of bodies without considering forces, and its application in robotic systems.

4: Configuration space (physics): Understand the concept of configuration space, where all possible positions and orientations of a system are represented.

5: Rigid body dynamics: Dive into rigid body dynamics, focusing on the motion of solid bodies in a mechanical system and its relevance to robotics.

6: Inverse kinematics: Explore inverse kinematics, a crucial aspect of robotic movement that involves calculating the required joint parameters to reach a target position.

7: Nonholonomic system: Learn about nonholonomic systems, where constraints on movement depend on the velocity, impacting the design of robotic systems.

8: Robot kinematics: This chapter delves into the specific application of kinematics to robots, covering how they achieve movement through joints and links.

9: Linkage (mechanical): Study the mechanical linkages that connect parts of a machine, enabling precise movement and functionality in robotic systems.

10: Overconstrained mechanism: Examine overconstrained mechanisms, which, despite having more constraints than necessary, can still function effectively in some systems.

11: Six degrees of freedom: A focus on the six degrees of freedom crucial to robotic arms and manipulators, enabling full control over movement in threedimensional space.

12: Parallel manipulator: Study the parallel manipulator, a mechanism in which multiple arms work in tandem to control movement with high precision.

13: Multibody system: Understand the dynamics of systems involving multiple interconnected bodies, critical in complex robotic systems.

14: Kinematic pair: Learn about kinematic pairs, which define the relative motion between components in a mechanism and their constraints.

15: Kinematic chain: This chapter discusses kinematic chains, where a series of interconnected links and joints create a system capable of controlled movement.

16: Holonomic constraints: Dive into holonomic constraints, where the restrictions on motion are directly related to the system's coordinates.

17: Chebychev–Grübler–Kutzbach criterion: Explore this criterion for analyzing the degree of freedom in mechanisms and determining the feasibility of mechanical systems.

18: Mechanism (engineering): A deeper look into mechanisms in engineering, focusing on their role in transforming motion within mechanical systems.

19: Kinematics equations: Learn about the mathematical equations that govern the motion of robotic systems, providing solutions to kinematic problems.

20: Freedom and constraint topologies: Study the topological relationships between degrees of freedom and constraints in robotic systems, essential for optimal design.

21: Cartesian parallel manipulators: Explore Cartesian parallel manipulators, which offer high accuracy and speed by using multiple arms arranged in parallel.
