1. A kinematic coupling for coupling an end effector to a robotic arm, the kinematic coupling comprising:
a first connector configured to engage with a second connector disposed on the robotic arm, the first connector comprising a recess or a contact, the second connector comprising the other of the recess or the contact corresponding to the first connector;
a third connector configured to engage with a fourth connector disposed on the robotic arm, the third connector comprising a fastener or a threaded recess, the fourth connector comprising the other of the fastener or the threaded recess corresponding to the third connector, wherein the fastener is configured to be received by the threaded recess, wherein the fastener is configured to be aligned with the threaded recess when the contact is received by the recess, wherein the fastener is configured to be moved between a first position in which the fastener is disengaged from the threaded recess and a second position in which the fastener is received within the threaded recess to couple the kinematic coupling to the robotic arm; and
a pivotable lever configured to pivot from a first position to a second position, wherein in the first position the fastener is disengaged from the threaded recess and in the second position, the lever moves the fastener into the threaded recess to couple the end effector to the kinematic coupling.
