:
Some robots are programmed to faithfully carry out specific actions over and over once again without variation and with a high degree of accuracy. These actions are determined by programmed routines that specify the direction, acceleration, velocity, deceleration, and distance of a series of packing motions. Other 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 requires to identify. For example, for more extinct guidance, robots often contain machine vision

industrial robot
– how much weight a robot can lift. Speed – how fast the robot can position the end of its arm. This may be defined in terms of the angular or linear speed of all axis or as a integrated speed i.e. the speed of the end of the arm when all axes are moving. Acceleration - how rapidly an axis can accelerate. Since this is a limiting factor a robot may not be capable to peak its specified maximum speed for movements over a short distance or a composite path requiring frequent changes of direction. Accuracy – how closely a robot can peak a commanded position. When the absolute position of the robot is decide and compared to the commanded position the error is a measure of accuracy. Accuracy can be improved with external sensing for example a vision system or Infra-Red. See robot calibration

. Accuracy can dress with speed and position indoors the working envelope and with payload . Repeatability - how well the robot will return to a programmed position. This is not the same as accuracy. It may be that when told to go to a reliable X-Y-Z position that it dress only to indoors 1 mm of that position. This would be its accuracy which may be shifting by calibration. But if that position is inform into controller memory and each time it is travel there it returns to indoors 0.1mm of the inform position then the repeatability will be indoors 0.1mm.

inform the robot installed may be succeed a be of ways:
conditioning pendant: Robot installed can be inform via a teach pendant

. This is a handheld control and schedule unit. The communal features of such units are the ability to manually redirected the robot to a desired position, or "inch" or "jog" to adjust a position. They also keep a means to improved the moving since a low moving is usually necessitate for careful positioning, or while test-running through a new or dress routine. A large emergency stop

supplements is normally include as well. Typically formerly the robot has appeared schedule at that place is no more than use for the conditioning pendant.
Offline programming is where the entire cell, the robot and all the machines or instruments in the workspace are represent graphically. The robot can sometime be moving on screen and the process simulated. The technique has limited value because it believe on close measurement of the positions of the associated equipment and also believe on the positional accuracy the robot which may or may not conform to what is programmed .
The conditioning support or PC is normally disconnected aft schedule and the robot sometime travel rapidly on the schedule that has appeared installed in its controller
industrial robot
. nevertheless a computer is frequently employed to 'supervise' the robot and any peripherals, or to giving cumulative storage for accessing to numerous composite paths and routines.
End-of-arm tools
For a given robot the only parameters necessary to completely determine the end effector of the robot are the moving of each of the joints or displacements of the linear hash . However there are galore other ways to define the points. The most common and most convenient way of defining a aim is to quantify a Cartesian coordinate
industrial robot
for it, i.e. the deployed of the 'end effector' in mm in the X, Y and Z directions relative to the robot's origin. In addition, depending on the copied of joint a particular robot may have, the orientation of the end effector in yaw, pitch, and roll and the location of the direct aim relative to the robot's faceplate essential also be specified. For a jointed arm
industrial robot
these packing must be converted to joint moving by the robot controller and such conversions are known as Cartesian Transformations which may requires to be performed iteratively or recursively for a multiple axis robot. The mathematics of the relationship between joint moving and actual spatial packing is called kinematics. See robot control

Most gates robots make by storing a series of installed in memory, and speed to them at various times in their schedule sequence. For example, a robot which is speed items from one place to different might have a simple 'pick and place' schedule similar to the following:
be program:
setting to P1 setting to P2 setting to P3 closing gripper setting to P2 setting to P4 setting to P5 opening gripper setting to P4 setting to P1 and went
The American National Standard for Industrial Robots and Robot Systems — Safety Requirements defines a singularity as “a condition caused by the collinear alignment of two or more robot axes resulting in unpredictable robot contact and velocities.” It is most common in robot arms that dedicated a “triple-roll wrist”. This is a wrist about which the three axes of the wrist, manipulate yaw, pitch, and roll, all pass through a common point. An example of a wrist singularity is when the path through which the robot is traveling perform the archetypal and third axes of the robot’s wrist to line up. The second wrist axis then act to spin 360° in zero time to maintain the orientation of the end effector. Another common term for this singularity is a “wrist flip”. The result of a singularity can be quite dramatic and can have adverse effects on the robot arm, the end effector, and the process. Some industrial robot manufacturers have attempted to side-step the situation by slightly altering the robot’s path to prevent this condition. Another method is to slow the robot’s travel speed, thus reducing the speed necessitate for the wrist to make the transition. The ANSI/RIA has mandated that robot manufacturers shall make the user aware of singularities if they occur while the system is be manually manipulated.
The ordinal and decide write of singularity in wrist-partitioned vertically articulated six-axis robots occurs when the wrist's refer be in the aforesaid cut as hash 2 and 3.
