This paper proposed a novel continuum arm driven by three contractile pneumatic muscles and one extensive muscle. This arm has variable compliance capabilities and low inertia capabilities, which is suited to any field with robot/human interaction. Statics model is proposed, and under different load and position situations using MATLAB software simulation has been done. Simulation results show that...
This paper proposes the use of UWSim (an underwater simulator) in combination with Simurv (a kinematic and dynamic library for Underwater Vehicle-Manipulator Systems control algorithms) and ROS (a well-known robotics framework) in order to simulate the dynamics of an Intervention Autonomous Underwater Vehicle and its application to the benchmarking of autonomous control algorithms in the field of...
Multi-agent robots, working in a group and sharing intelligent information, have several advantages over a single agent robot such as simplicity in agent design, better performance, increased fault tolerance and spatially distributed sensing. Applications of such systems are abundant in various fields of engineering and sciences. Multi-agent robots using leader-follower formation comprises of a group...
A robotic system of crane systems is proposed and simulated for a vanilla pollination application. The system could be used for other applications where a grid of posts is serviced in an area suitable for overhead cranes. Existing crane systems could work together with new crane equipment in a hierarchical manner. A docking crane system with two or more six degrees of freedom cranes services the area...
A digital integrated development platform, which is based on Pro/E, ADAMS, ANSYS and Matlab, is introduced in this paper. A type of 6-DOF industrial robot for laser cutting is developed on this platform. In the virtual environment, the development efficiency is improved, as well as the reliability of the robot. The 3D parametric model of the laser cutting robot is firstly built by using Pro/E. Through...
In odder to improve positioning precision and decrease the exceed initial value of solar cell transfer robot, we design a kind of PID controller with fuzzy self-adjusting function based on fuzzy control technique, solve the problem that the PID-controller can not adjust parameters itself on line. The result of simulation in fuzzy logic toolbox of Matlab proves that the controller possess both the...
This paper presents the ground work prepared for turning a bucket wheel reclaimer (BWR) into a robotic arm for operation automation. BWR has been widely used in dealing with bulk materials by removing them from the conveyor and stack them as well as to load stacked materials onto the in-feed conveyor, such as in mining industry. Generally speaking, current BWRs are manually operated, remotely operated,...
Pneumatic muscles mimic function of human muscles and are used as robot actuators. The intelligent pneumatic muscle (IPM) with shape memory alloy (SMA) wires braided shell was proposed to improve characteristics. The mechanism was designed and prototype test-bench was made. Output force model was established through static force equilibrium analysis. The equation between temperature and contraction...
The paper presents a novel structure of the Isoglide3 parallel robot (IG3PR), as an effective robotic device with three degrees of freedom manipulation. The IG3PR manipulator offers the characteristics, advantageous relative to the other parallel manipulators (light weight construction), while on the other hand alleviates some of the traditional weaknesses of parallel manipulators, (extensive use...
Firstly, a tomato harvesting robot in greenhouse is introduced, the workspace of which is visually verified that it covers the tomatoes distribution space of one plant and hasnpsilat cavity by the pose diagrams of end-effector, and the designed robot has high flexibility. Subsequently the forward and inverse kinematics of harvesting robot is analyzed, so the range of joint variables and the inverse...
In this paper, in order to complete multitask underwater, we will propose a kind of novel underwater multi-microrobot system which is consist of a mother submarine and several microrobots with ICPF (ionic conducting polymer film) actuators. Then we simply design the structure and close-loop control system of the microrobot system, study the mission planning and coordinate motion with the formation...

In recent years, studies about control methods for complex machines and robots have been developed rapidly. Biped robots are often treated as inverted pendulums for its simple structure. But modeling of robot and other complex machines is a time-consuming procedure. A new method of modeling and simulation of robot based on SimMechanics is proposed in this paper. Physical modeling, parameter setting...
