It is difficult to control the movement of the robot arm due to its nonlinear structure. PID controller is still in the world because of its simplicity in designing this controller as the main controller. The nonlinear control technique is very complicated, and this is not very interesting in the controller. While fuzzy control has a better performance, it incorporates a fuzzy control with ...

There are many design factors and choices when mounting a vision system for robot control. Such factors may include the kinematic and dynamic characteristics in the robot’s degrees of freedom (DOF), which determine at what velocities and fields-of-view a camera can achieve. Another factor is that additional motion components (such as pan-tilt units) are often mounted on a robot and introduce sy...

In this paper a new procedure for type synthesis of low-DoF parallel robots based on screw theory is presented. The motivation of these work is that for many industrial applications, in particular in the machine-tool field, less than 6 degree of freedom (6-DoF) may be needed to complete the task. For example, for milling operation in the machine-tool domain, the rotation of the platform around ...

This paper presents an iterative algorithm to find a inverse kinematic solution of 5-DOF robot. The algorithm is to minimize the iteration number. Since the 5-DOF robot cannot give full orientation of tool. Only z-direction of tool is satisfied while rotation of tool is determined by kinematic constraint. This work therefore described how to specify the tool direction and let the tool rotation ...

The objective of this paper is path planning of a 3 DOF planer robot with hydraulic actuator using genetic algorithm. First the geometric and kinematic parameters of robot were established. The equations of motion are derived by Lagrange method. We proposed the model for proportional valve and hydraulic actuators. Then using the genetic algorithm we minimized the hydraulic energy consumption as...

development of an intelligent huggable robot named ANTY (Fig.1) that will interact with hospitalized children to distract and support them during their stay in hospital. This robot is subject of a multidisciplinary project covering research opportunities not only in mechanical design, vision, speech and AI, but also in sociology and psychology. The main goal of the first phase is the developmen...

The kinematics of manipulators is a central problem in the automatic control of robot manipulators. Theoretical background for the analysis of the 5 Dof Lynx-6 educational Robot Arm kinematics is presented in this paper. The kinematics problem is defined as the transformation from the Cartesian space to the joint space and vice versa. The Denavit-Harbenterg (D-H) model of representation is used...

To explore an issue of a human-like motion, we have constructed a human-like biped robot called WABIAN-RII (WAseda BIped humANoid robot-Revised II) that has a total of fortythree mechanical degrees of freedom (DOF); two six DOF legs, two ten DOF arms, a four DOF neck, four DOF in the eyes and a torso with a three DOF waist. For human-robot symbiosis, the biped humanoid robot is required to have...
