An automated locking joint can include a first member, a second member, a joint, a locking structure, and a positioning device. The joint can connect the first member with the second member. The second member can be pivotable about the joint relative to the first member. The locking structure can be positionable between a lock position that prevents pivoting of the second member about the joint and an unlock position that allows pivoting of the second member about the joint. The positioning device can automatically move the locking structure from the lock position to the unlock position or from the unlock position to the lock position.
