Robotics Configuration Space and Degrees of Freedom Quiz

Configuration Space in Robotics

• Refers to the set of all possible positions and orientations of a robot's joints and links.
• Each point in the configuration space represents a unique configuration of the robot.

Degrees of Freedom in Robotics

• Indicates the number of independent movements a robot can make.
• Each joint typically contributes to one degree of freedom.

Joint Types Not Allowed in Typical Robots

• Non-conventional joints, such as those exhibiting infinite or highly restricted movement, are typically avoided.
• Examples include joints that can rotate freely in all directions without limits.

Grubler's Formula

• A mathematical formula used to calculate the degrees of freedom in a mechanical system.
• Commonly expressed as DOF = 3(L - 1) - 2J - H, where L is the number of links, J is the number of joints, and H is the number of higher pairs.

Planar Four-Bar Linkage

• A simple mechanical system consisting of four links connected in a loop by four joints that allow rotation.
• It is used to convert rotary motion into linear motion and vice versa.

Degrees of Freedom of a Four-Bar Linkage According to Gruebler's Formula

• Based on Gruebler's formula, a four-bar linkage typically has one degree of freedom.
• This implies that the system can perform one independent motion among its components.
