Example Concept: In 7-DOF manipulators, the extra degree of freedom provides redundancy, which can be used to optimize motion paths by avoiding obstacles or minimizing energy consumption. However, this also increases the complexity of the inverse kinematics and motion planning algorithms, as they must evaluate multiple potential solutions for each target pose. Algorithms like RRT (Rapidly-exploring Random Trees) or PRM (Probabilistic Roadmaps) are often employed to handle this complexity by exploring the configuration space more efficiently.
