Types of Robots
1.Manipulators
“A mechanism, usually consisting of a series of
segments,
jointed
or
sliding
relative
to
one
another,
for
the
purpose
of
grasping
and
moving
objects
usually
in
several
degrees
of
freedom.
It
may
be
remotely
controlled
by
a
computer or by a human."

Robotics Terminology
End
- effector:
The tool, gripper,
or other device mounted at theend of a manipulator, foraccomplishing useful tasks Workspace:
The volume in space that a robot’s end-
effector can reach, both in position and orientation Position:
The translational (straight-line) location of
something. Orientation:
The rotational (angle) location of
something. Link:
A rigid piece of material connecting joints in a
robot
Robotics Terminology
Joint:
The device which allows
relative motion between twolinks in a robot.
Kinematics:
The study of motion without
regard to forces.
Dynamics:
The study of motion with regard
to forces.
Sensor:
Reads variables in
robot motion for use incontrol.
Robotics Terminology
Accuracy^ • The ability of a robot to go to the specified
position without making a mistake.
- It is impossible to position a machine exactly.• Accuracy is therefore defined as the ability of
the robot to position itself to the desiredlocation with the minimal error (usually 25mm).
Repeatability^ • The ability of a robot to repeatedly position
itself when asked to perform a task multipletimes.
Robot Classification
Drive Technology.
Which source of
power drives the joints of the robot.
Work-envelope geometries.
Points
in space which can be reached by theend-effector.
