Defining parameters[ edit ] Number of axes — two axes are required to reach any point in a plane; three axes are required to reach any point in space. To fully control the orientation of the end of the arm robos industriais.
Degrees of freedom — this is usually the same as the number of axes. Working envelope — the region of space a robot can reach. Kinematics — the actual arrangement of rigid members and joints in the robot, which determines the robot's possible motions. Carrying capacity or payload — how much weight a robot can lift.
Speed — how robos industriais the robot can position the end of its arm.
This may be defined in terms of the angular robos industriais linear speed of each axis or as a compound speed i. Acceleration — how quickly an axis can accelerate.

Since this is robos industriais limiting factor a robot may not be able to reach its specified maximum speed for movements over a short distance or a complex path requiring frequent changes of direction.
Accuracy — how closely a robot can reach a commanded position. When the absolute position of the robot is measured 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.
Accuracy can vary with speed and position within the working envelope and with payload see compliance. Repeatability — how well the robot will return to a programmed position.
Robos industriais is not the same as accuracy. This would be its accuracy which may be improved by calibration. But if that position is taught into controller memory and each time it is sent there it returns to within 0.
Accuracy and repeatability are different measures.

Repeatability is usually the most important criterion for a robot and is similar to the concept of 'precision' in measurement—see accuracy and precision. ISO robos industriais sets out a method whereby both accuracy and repeatability can be measured.

Typically a robot is sent to a taught position a number of times and the error is measured at each return robos industriais the position after visiting 4 other positions.
Repeatability is then quantified using the standard deviation of those samples in all three dimensions. A typical robot can, of course make a positional error exceeding that and that could be a problem for the process.
Moreover, the repeatability is different in different parts of the working envelope and also changes with speed and payload.

ISO specifies that accuracy and repeatability should be measured at maximum speed and at maximum payload. But this results in pessimistic values whereas the robot could be much more accurate and repeatable at light loads and speeds.
Repeatability in an industrial process is also robos industriais to the accuracy of the end effector, for example a gripper, and even to the design of the 'fingers' that match the gripper to the object being grasped.
For example, if a robot picks a screw by its head, the screw could be at a random angle.

A subsequent attempt to insert the screw robos industriais a hole could easily fail. These and similar scenarios can be improved with 'lead-ins' e. Motion control — for some applications, such as simple pick-and-place assembly, the robot need merely return repeatably to a limited number of pre-taught positions.
For more sophisticated applications, such as welding and finishing spray paintingmotion must be continuously controlled to follow a path in space, with controlled orientation and velocity. Power source — some robots use electric motorsothers use hydraulic actuators.
