ABSTRACT:
A parallel robot comprises a base, three set of arm assemblies disposed on the base at a predetermined spacing, and a bracket member which is supported by the arm assemblies and to which an end effector is attached. Each of the arm assemblies comprises a pair of motors mounted on the base to face each other with a predetermined clearance and a pair of arms which are supported by the motors to be swung, respectively. Each of the arms comprises a first arm portion and a second arm portion. The first arm portion and the second arm portion of each arm are connected with each other through a first joint means, and the second arm portion of each arm is connected with the bracket through a second joint means.
