An exemplary translational branch joint for a parallel robot includes a swing arm connected to a four-bar linkage. The four-bar linkage includes two parallel connecting bars, a first link member, a second link member, and joint members. The first link member and the second link member connect the connecting bars. Each joint member comprises a first joint portion and a second joint portion extending from the first joint portion. The first joint portion has a first axis, and the second joint portion has a second axis substantially perpendicular to the first axis. The first joint portions of the joint members are rotatably connected to ends of the first link member and the second link member, and the second joint portions of the joint members are rotatably connected to ends of the connecting bars.
