The number of degrees of freedom of one of these systems is related to the number of joints by the mobility formula. For 10 points each:
[10h] Name these idealized systems consisting of rigid bodies coupled together by joints.
ANSWER: kinematic chains [or linkages; prompt on mechanisms; prompt on chains]
[10m] If several of these statements for a kinematic chain are redundant, a kinematic chain that the mobility formula predicts to have zero degrees of freedom can still move. Joints are typically modelled as a holonomic one of these statements.
ANSWER: constraints [accept holonomic constraints; accept overconstrained systems or mechanisms]
[10e] Kinematic chains are commonly used to model the manipulators of these machines, which interact with their environment using an end-effector. These autonomous machines are capable of performing complex tasks.
ANSWER: robots [accept robotic manipulators]
