  Industrial Robots   (Site not responding. Last check: 2007-11-05)
The field of industrial robotics may be more practically defined as the study, design and use of robot systems for manufacturing (a top-level definition relying on the prior definition of robot).
Other industrial robots are much more flexible as to the orientation of the object on which they are operating or even the task that has to be performed on the object itself, which the robot may even need to identify.
Unimation robots were also called programmable transfer machines since their main use at first was to transfer objects from one point to another, less than a dozen feet or so apart.

 designfax - Feb 2000 - Precision Single-Piece Flexible Couplings In Robots
Robot arm speeds of 2 meters (80 inches) per second and position accuracies of 0.01mm (0.0004 in.) are typical for high performance vision robots used in semiconductor electronic component assembly and material handling applications.
The Cartesian coordinates robot best represents this type of robot, while the cylindrical coordinates robot is also used in these less demanding applications.
A miniature single-piece flexible coupling is used to connect the drive motor shaft to the lead screw used in the Cartesian coordinate robot arm as well as the height (z - zeta) axis and the extend/retract (g - gamma) axis in the cylindrical coordinates robot arm.

 Robot welding - Wikipedia, the free encyclopedia
Robot welding is the use of mechanized programmable tools (robots), which completely automate a welding process by both performing the weld and handling the part.
Robot welding is a relatively new application of robotics, even though robots were first introduced in United States industry during the 1960s.
The manipulator is what makes the robot move, and the design of these systems can be categorized into several common types, such as the SCARA robot and cartesian coordinate robot, which use different coordinate systems to direct the arms of the machine.

 Using a PID-based Technique For Competitive Odometry and Dead-Reckoning
Second, the robot was able to rely on the accuracy of its dead-reckoning calculations because of a machine-control algorithm that held it to a straight-line path when it was traversing corridors.
If the robot were to execute a turn with a radius equal to half the width of the course (9 inches, 22.9 cm), it could begin the turn right at the end of one corridor and complete the turn at the beginning of the next.
Thanks also go to the the members of the Connecticut Robotics Society, in particular Bill Ruehl and Jake Mendelssohn whose good sense and extensive knowledge of robotics are always an inspiration, and to John Gallichotte who organized the CRS odometry event and made important suggestions regarding this article.

 The juggling robot
The installation comprises a 2 dimensional high-speed robot arm with a structure based on the DELTA robot developed at the Microengineering institute of the EPFL.
The neural network approach consists in teaching to a neural network the correspondence between the X and Y coordinates of the gripper, as seen from the camera, and the angular coordinates of the motors.
It learns the relation between the cartesian coordinates X Y and the angles of the arms A and B. Once the network is organised, its knowledge can be exploited to juggle.

 Coordinate systems in Flat
The origin of the robot's coordinate system is the center of the robot (assumed here to be the circular robot "Spot").
The positive X-axis of the robot extends in whatever direction the robot is facing.
For a two-laser Spot, the lasers are mounted on the sides of the robot at (0, -140mm) and (0, 140mm) for the left and right ones respectively.

 Robot encyclopaedia
Cartesian velocity refers to the rate of change of Cartesian pose.
Loosely speaking, Cartesian position refers to the position (x, y, z) of the tool of the robot with respect to a given frame of reference.
Also known as a gantry robot, this refers to a robot which has three prismatic joints, all mutually perpendicular to each other.

 ST robotics software   (Site not responding. Last check: 2007-11-05)
To teach the robot you first move the arm to the required position using any of the means provided and secondly record the coordinates of that position.
Cartesian coordinates, absolute or relative coordinates, name of any object in that position etc. The robot can also learn positions itself, for example by searching or by computing a target position or by modifying a taught path to suit a new requirement.
The robot can be programmed to learn it's own coordinates (self teaching), for example to modify a path you taught it so that it changes as a target position changes.

 Robot
In the initial setting of the robot arm, each servo is set to no rotation (0 degrees), and the links in the robot arm coincide with the z-axis.
Counterclockwise rotations about a coordinate axis are produced with positive rotation angles, if we are looking along the positive half of the axis toward the coordinate origin.
Given the number of links in a robot's arm, their lengths, and the proposed settings of the servos, first determine if the proposed positioning of the arm is allowable.

 Sankyo Robotics - CCR's
CCRs are highly configurable, rectilinear robot systems which, in a basic configuration, include an X and Y axis.
CCRs are also typically very repeatable, have better inherent accuracy than a SCARA or jointed arm, and perform 3D path-dependent motions with relative ease.
However, the CCR’s key feature is its configurability – the ability you have to configure and size the CCR to best meet your application needs.

 Robots & Robot Controllers
As may be known from the name, the robot has compliance only in specific directions (X and Y directions) and has high rigidity in other direction (Z direction), and thus, has been designed mainly for automation of assembling works.
Although SCARA robot is examined by comparing with cartesian coordinate robot in many cases owing to its operating range, it can be said that SCARA robot is suitable for works requiring speeds on three axes or four axes motions because of its excellent cost-performance ratio.
The features of this robot include its small installation area that provides higher degree of freedom in design of a system, and in addition, provides an advantage that, in case the system is disused in the future, the robot can be installed easily on another system.

 ROBOTIC PATHWAY GUIDANCE AND OBSTACLE AVOIDANCE
The robotic model’s goal is to successfully maneuver down a specified pathway, maintaining the pathway constraints while avoiding obstacles positioned in the pathway.
  A simulation of the simple autonomous robotic model is employed using the pathway and obstacle model’s positions on a Cartesian coordinate system to provide input signals or stimuli by which the robot then reacts or responds.
The significance of this research is to provide a simple, yet affective method that may ultimately lead to the development of an autonomous mobile robot model that is more robust than the original model.
