One end of the chain, the base, is generally fixed and the other end is free to move in space and holds the tool or end-effector. Figure 7.1 shows two classical robots that are the precursor to all arm-type robots today. Each robot has six joints and clearly the pose of the end-...
As a first step in control of two-arm robots, it is necessary to determine the kinematic relationships between the two end-effectors at any instant. The elements Of the orientation-position matrix of a dual (slave) arm are obtained in terms of those of the main (master) arm, so that th...
• Inverse kinematics (Sect.16.2): Given a desired position of the robotic arm, whatsequence of commands will bring it to that position?Forward kinematics is relatively easy to compute because the calculation of thechange in position that results from moving each joint involves simple trigonometry...

Among them, describing the kinematics of the robot arm using screw theory has the advantages of beautiful form and clear physical meaning. However, this theory is relatively complex, requiring complex operations such as matrix operations and vector cross products in the specific calculation process, ...
Vision assisted robotic assembly of miniature parts The objective of this thesis was to design and build a work cell that utilized a robotic vision system to assemble a micro motor. The work cell design consisted of an Adept SCARA robot with a vision system, end-of-arm tooling, and a comb...
A 6 degree of freedom (DOF) robot arm is controlled using the ROS2 robotic manipulation platform, MoveIt 2. The ROS2 Humble version of MoveIt 2 is used, which runs in a Docker container on an Nvidia Jetson Nano board. The robot arm is equipped with an Intel Realsense D415 depth camer...
To initialize an instance of Robot, DH parameters need to be provides. They should be given by an n*4 matrix, where n is the number of axes the robot has, most commonly six. The matrix should be in following format: daalphatheta x x x x x x x x ... ... ... ... In this...
the robotic arm because of the high speed of some parts of the robot while passing these singularities is dangerous to the human partner while human and the robot are in physical contact with each other. Kinematics can be further classified into two broad categories: ...
