Abstract: The present invention relates to an additive manufacturing system and its methods. The system includes a material conveyor, an energy source, and a micro-forging device. The material conveyor is configured to convey material. The energy source is configured to direct an energy beam toward the material, the energy beam fuses at least a portion of the material to form a solidified portion. The micro-forging device is movable along with the material conveyor for forging the solidified portion, wherein the micro-forging device comprises a first forging hammer and a second forging hammer, the first forging hammer is configured to impact the solidified portion to generate a first deformation, and the second forging hammer is configured to impact the solidified portion to generate a second deformation greater than the first deformation.

Abstract: A robotic system includes a support structure, a motor mount assembly, first and second parallel chains, a serial translation assembly, a sensor and a control module. The motor mount assembly includes rotary motors, where the rotary motors include a first rotary motor and a second rotary motor. The first and second parallel chains are connected to the movable platform, the rotary motors and the motor mount assembly. The serial translation assembly is connected to the supporting structure and the motor mount assembly and includes a linear actuator and a third rotary motor. The sensor is connected to the movable platform and detects force applied by a human operator on the movable platform and generates a signal indicative of the force applied. The control module controls the rotary motors and the third rotary motor based on the signal to assist the human operator in moving the movable platform.

Abstract: A method, device, and apparatus for optimizing unbalanced loads covered by a same network and a storage medium are provided. The method includes: determining whether loads of cells covered by a same network are balanced; determining, if the loads of the cells are unbalanced, a cell with a highest network load rate and a cell with a lowest network load rate in the cells; determining a target offset parameter corresponding to a predetermined index according to a timing advance and the number of sampling points of each of the cell with the highest network load rate and the cell with the lowest network load rate; and adjusting a load of the cell with the highest network load rate and a load of the cell with the lowest network load rate based on the target offset parameter.
