hao Jiang (China,1992) completed Environmental Design at Soochow University, China. During the period he focused on the relationship between the environment

and the Architecture.He also won the Asia Architecture And Urbanism Alliance Architectural design best creative award.He served as an interior designer in the famous company GOLD MANTIS. Recently he finished the MArch Architectural Design at the Bartlett School of Architecture(UCL). During this period he is committed to developing 3D printing at the architectural scale. He further studied the combination of 3d printing and other materials so as to increase the efficiency of printing and reduce the cost as well.

05 ROBOTIC ASSEMBLY pick and place process

W

e (INTILE) aims to achieve a fully reversible and robotic assembly structure. To achieve this point, an interlocking system has been

developped. This mechanism allows us to assemble and disassemble the pieces as many times is required. Two scenarios has been analyezed, the first one is based on fabrication and assemble on a factory and a seconde one where the fabrication and assemble is directly on site. The main different between both scenarios is based on the shipping method. In the first one the pieces has to shipped to the place once the has been produced, this fact produced and increment of the cost of the shipping. On the other hand, the second scenario allow as to ship the robotic arm and the extruder whereever is needed. By this method, the shipping cost is reduced drastically.

Gripper part

The project InfiniteVoxels aims to achieve a fully robotic assembly through a robotic arm. A pneumatic gripper has been used to grip the pieces, the gripping part of the gripper has been customized to be adapted to the dimension of the pieces. There are two bases were designed for picking and placing. According to robot working space and the limited rotation of the robot arm, small pieces could be picked from three different surfaces, Long piece and floor slab could be picked by one point.
