When selecting an industrial robot there are many things which need to be considered, such as: what is its purpose, how fast does it need to move, what precision of movement does it need, will it be a (a) robot
Has the robot’s tool moving in a linear motion along each of the Cartesian coordinates (x, y, z). This type of configuration can sweep out a box-like work envelope.
Spherical
Cylindrical
Cartesian
Selective Compliance Articulated Robot Arm (SCARA)
This type of robot is the most commonly pictured when referring to an industrial robot. As a minimum, it needs to have at least a shoulder joint, an elbow joint, and a wrist joint. Many examples of these configurations can have both major and minor axes.
Articulated
Delta (Parallel)
Spherical
Cartesian
Allows its tool to rotate around a central axis. The tool can also move towards and away from the central axis, plus up and down the central axis. This configuration creates a work-volume in the shape of a cylinder.
Delta (Parallel)
Selective Compliance Articulated Robot Arm (SCARA)
Cylindrical
Cartesian
Uses pivot points to allow its tool to move in a combination of the Cartesian and the cylindrical motions. This allows the tool to move more quickly, and move more easily in certain motions, such as moving in an arc.

In order to define a movement in space, the movement needs to be measured. Measurements require a starting point or zero point, called a (a) point.
What is the work-volume or work envelope of the V5 Workcell?
The area above the limit of the arm which would be considered a singularity.
all the space it can move through, in all directions.
The starting point would be known as the calibration point for the drawing
What is the calibration point in a robot configuration?
A set of instructions
The workspace the robot sweeps through
starting point or zero point that is used to measure the robot's movements
An area in which a robot cannot move
What is a singularity in robot's movements?
a starting point for robot's movements
all the space a robot can move through, in all directions
An area in which the robot cannot move
A robot can not move without a (a)
Which is NOT a type of actuator?
hydraulic actuator
pneumatic actuator
Stepper motor
robotic claw
A (a) motor has a sensor/sensors which can be used to control things like position, speed, and acceleration of its shaft.
A pneumatic actuator uses an air compressor to pressurize air.
Valves release the air pressure through pneumatic tubing.
The air pressure in the tubing can cause the shaft of a pneumatic cylinder to move out or move in.
False
True
Hydraulics actuators use a pump to pressurize hydraulic fluid. Valves release the fluid through hydraulic hoses. The pressure in the hoses can cause the shaft of a hydraulic cylinder to move out or move in.
True
False
There are two ways an actuator can move a robot's component. In this model, an actuator’s shaft spins a system which transfers the force to the component on the robot. This system might use gears, sprockets and chain, pulleys and belts, or another type of power transmission between the actuator and the component it is moving.
direct drive
indirect drive
