The present application relates to control command generation methods and systems for three-dimensional surface weaving. The control command generation method comprises the steps of: rebuilding a desired three-dimensional object into a three-dimensional surface mesh; converting the three-dimensional surface mesh into readable weaving information; and generating control commands from the readable weaving information to instruct a three-dimensional surface weaving system. The control command generation method generally comprises a pipeline of software including the mesh processing, weaving map extraction and command generation. The control command generation method can enable three-dimensional surface weaving function.

Control command generation methods and systems for three-dimensional surface weaving

Systems, devices and methods for three-dimensional surface weaving are disclosed herein. The system includes a jacquard device, a weaving device and a roller matrix. The jacquard device configured to selectively raise or lower the warp threads to form a shed for the weft thread to travel; the weaving device configured to carry the weft thread into the shed and weave the weft thread on the warp threads; and the roller matrix with individually controlled rotate apparatus configured to control the warp threads to move forward or backward. The warp threads come from rotate apparatus installed on the roller matrix. The rotate apparatus is controlled individually to forward or reverse rotate, so that the attached warp thread is able to be longer or shorter. As the warp threads can be shortened during weaving process, the three-dimensional surface can be produced.

A robotic constructing system based on a cable-driven robot for constructing a structure formed by objects such as bricks is provided. The process of laying the bricks is performed by the cable-driven robot autonomously. The bricks are provided to the robotic constructing system by an external conveyor and a robot arm of the robotic constructing system is configured to pick up the bricks. The robot arm is then configured to place the bricks in a position to receive an adhesive from an adhesive dispenser of the robotic constructing system and further to load the bricks onto a linear rail. The linear rail can be configured to place the bricks within the proximity of the cable-driven robot. The cable-driven robot can be configured to pick up the bricks and lay the bricks in the designated position of a three-dimensional space.

The present invention discloses a task specific robot for the procedure of endoscopic submucosal dissection (ESD). This robot has two arms with nine degrees of freedom (DOF), and the capability of tissue elevation and dissection. An optimal design of these robot arms requires the use of shape memory alloy (SMA) wire and steel wire actuators to develop an improved actuation mechanism, which enables force to be transmitted to the distal tip of the robot arms for an efficient tissue elevation and dissection.
