A system for placing objects on a surface. The system may include a base, a robotic arm coupled, at an end thereof, to the base, an end effector coupled to the other end of the robotic arm. The end effector may be configured for releaseably coupling to an object to be placed on the surface. The system may further include one or more sensor units on a sensor frame. The one or more sensor units may be configured for sensing a two-dimensional profile data including at least two two-dimensional profiles together comprising at least three boundary portions of the object to be placed and at least three boundary portions of objects on the surface. At least two of the three boundary portions of the object to be placed may be from substantially non-parallel sides. At least two of the three boundary portions of the objects on the surface may be from substantially non-parallel sides. The system may further include a processor configured to determine at least three degrees of freedom of the object to be placed with respect to the sensor frame and six degrees of freedom of the sensor frame with respect to the objects on the surface in a three-dimensional space for determining a current pose of the object to be placed with respect to the objects on the surface based on the two-dimensional profile data. Further, the system may be configured to place the object based on differences between the current pose and a desired pose of the object to be placed determined from a model of objects on the surface in the three-dimensional space.

System for placing objects on a surface and method thereof

A mobile manufacturing device and a method for producing three-dimensional lattice or mesh structures, wherein the mobile manufacturing device is a mobile device adapted to move along a three-dimensional structure to be produced, in particular while performing both translation and rotation movements in three-dimensional space, and wherein the mobile manufacturing device includes a means for detection of its position relative to the dimensional structure to be produced, so that the mobile manufacturing device is able to produce the three-dimensional structure as an autonomous robot.

Method of fabricating a 3-dimensional structure, mesh formwork element for fabricating a 3-dimensional structure, and method of fabricating the same. The method of fabricating a 3-dimensional structure comprises providing a mesh formwork element such that a cavity bound by at least two opposing portions of the mesh formwork is formed; accumulating a material in the cavity; and allowing the material to harden; wherein apertures in the at least two opposing portions of the mesh formwork element are adapted to the hydro-static pressure of the accumulated material or vice versa such that at least two surfaces of the hardened material substantially take on the respective shapes defined by the two opposing portions of the mesh formwork element.

Apparatus () for vertical () slip forming of concrete walls and columns (). The apparatus comprises an attachment portion () for a frame with a slipform assembly inside comprising an extrusion form providing side walls defining a cavity and actuators () to adjust the position of the side walls forms essentially arranged along the longitudinal axis of the slipform assembly. A concrete supply () is connected with the slipform assembly for delivering concrete () to that cavity through the top open surface. A mechanism () is provided for vertically displacing () that slipform assembly incrementally relative to the frame. Thus, a concrete structure () having a vertical orientation is continuously cast. The actuators () adjust the position of the side walls during the incremental vertical movement () of the slipform assembly to create new forms for a column or wall with variable diameter, variable form and/or twisted.
