Explore the fundamental concept of degrees of freedom in robotics through this comprehensive video lesson. Learn the definition and significance of degrees of freedom for rigid bodies in 2D and 3D spaces, and understand how robot joints constrain motion. Discover various types of joints used in robotics, including revolute, linear, universal, spherical, cylindrical, and helical joints. Master Grübler's Formula to calculate degrees of freedom for any mechanism, with practical applications to planar robot arms, four-bar linkages, Stewart platforms, and Delta robots. Gain insights into complex scenarios, such as a 7 DOF robot arm carrying a tray with drinks, to deepen your understanding of robotic motion and constraints.
