Through multi-robot cooperative carrying simulation experiment in dynamic environment,it\'s shown that the collision number between robots and obstacles is effective decreased after using role changing and reinforcement learning method,cooperative carrying is successfully achieved and great learning effect is made.

The Research of Vision Servo and Control Mode on Frame-steel-transmitting Robot;

Dynamic material handling route planning based on real-time operation conditions;

The Research on VR-based Material Handling Remote Operating Simulation;

The survey about the development of electric control in technology material handling systmes in China is given.

Fork s appliance, as an advanced machine of materials handling, has changed the traditional thoughl ofmaterials handling mode, and it made fork become a handling tool which has many functions of forking, clamping, lifting.

The paper analyzes every factors that may improve the efficiency of materials handling system,gives out the process of how to study the system and establishes the optimized model based on the factors.
