Various embodiments relate to magnetically moveable displacement devices or robotic devices. Particular embodiments provide systems and corresponding methods for magnetically moving multiple movable robots relative to one or more working surfaces of respective one or more work bodies, and for moving robots between the one or more work bodies via transfer devices. Robots can carry one or more objects among different locations, manipulate carried objects, and/or interact with their surroundings for particular functionality including but not limited to assembly, packaging, inspection, 3D printing, test, laboratory automation, etc. A mechanical link may be mounted on planar motion units such as said robots.

A portable work module includes a combination of prismatic and revolute joints for positioning and orienting a robotic end effector for performing a task within confined space. For example, the portable work module may include telescoping arm integrated with wrist having a plurality of degrees of freedom with respect to telescoping arm. The portable work module includes an insert that is secured with respect to an access port of confined space, said access port serving as a reference location for calculating the position of the robotic end effector within confined space. The portable work module is configured to have a compacted configuration for insertion into confined space, and an extended configuration for performing tasks within confined space. In some examples, the portable work module is modular, such that the robotic end effector or other components may be selectively removed and replaced.

In one aspect, a translational parallel manipulator is provided and includes a fixed platform including three guide members. The three guide members include first ends and second ends, and the first ends of the three guide members are all coupled to each other and the second ends of the three guide members are all spaced-apart from each other. The manipulator also includes a movable platform spaced-apart from the fixed platform and three serial subchains coupled between the three guide members and the movable platform. In one aspect, a translational parallel manipulator is provided and includes a fixed platform, a movable platform spaced-apart from the fixed platform, and a plurality of subchains coupled between the fixed platform and the movable platform. At least one of the plurality of subchains includes no more than four one degree-of-freedom joints.
