Glossary of robotics

Robotics is the branch of technology that deals with the design, construction, operation, structural disposition, manufacture and application of robots. Robotics is related to the sciences of electronics, engineering, mechanics, and software.

The following is a list of common definitions related to the Robotics field.



A

 * Actuator, a motor that translates control signals into mechanical movement. The control signals are usually electrical but may, more rarely, be pneumatic or hydraulic. The power supply may likewise be any of these. It is common for electrical control to be used to modulate a high-power pneumatic or hydraulic motor.
 * Aerobot a robot capable of independent flight on other planets. A type of aerial robot.
 * Arduino The current platform of choice for small-scale robotic experimentation and physical computing.

 * Explosive ordnance disposal robot A mobile robot designed to assess whether an object contains explosives; some carry detonators that can be deposited at the object and activated after the robot withdraws.

F

 * FIRST.For Inspiration and Recognition of Science and Technology, is an organization founded by inventor Dean Kamen in 1989 in order to develop ways to inspire students in engineering and technology fields.
 * Forward chaining a process in which events or received data are considered by an entity to intelligently adapt its behavior.

G

 * Gynoid A humanoid robot designed to look like a human female.

H

 * Haptic tactile feedback technology using the operator's sense of touch. Also sometimes applied to robot manipulators with their own touch sensitivity.
 * Hexapod (platform) A movable platform using six linear actuators. Often used in flight simulators and fairground rides, they also have applications as a robotic manipulator.
 * Hexapod (walker) A six-legged walking robot, using a simple insect-like locomotion.
 * Human–computer interaction.
 * Humanoid A robotic entity designed to resemble a human being in form, function, or both.
 * Hydraulics, the control of mechanical force and movement, generated by the application of liquid under pressure. c.f. pneumatics.

I

 * Industrial robot A reprogrammable, multifunctional manipulator designed to move material, parts, tools, or specialized devices through variable programmed motions for the performance of a variety of tasks.
 * Insect robot A small robot designed to imitate insect behaviors rather than complex human behaviors.

K

 * Kalman filter, a mathematical technique to estimate the value of a sensor measurement, from a series of intermittent and noisy values.
 * Kinematics, the study of motion, as applied to robots. This includes both the design of linkages to perform motion, their power, control and stability; also their planning, such as choosing a sequence of movements to achieve a broader task.
 * Klann linkage, a simple linkage for walking robots.

L

 * Linear actuator A form of motor that generates a linear movement directly.

M

 * Manipulator (device) or gripper. A robotic 'hand'.
 * Mobile robot A self-propelled and self-contained robot that is capable of moving over a mechanically unconstrained course.
 * Muting The deactivation of a presence-sensing safeguarding device during a portion of the robot cycle.

P

 * Parallel manipulator an articulated robot or manipulator based on a number of kinematic chains, actuators and joints, in parallel. c.f. serial manipulator.
 * Pendant Any portable control device that permits an operator to control the robot from within the restricted envelope (space) of the robot.
 * Pneumatics, the control of mechanical force and movement, generated by the application of compressed gas. c.f. hydraulics.
 * Powered exoskeleton, is a wearable mobile machine that allow for limb movement with increased strength and endurance.
 * Prosthetic robots are programmable manipulators or devices for missing human limbs.

R

 * Remote manipulator A manipulator under direct human control, often used for work with hazardous materials.
 * Robonaut a development project conducted by NASA to create humanoid robots capable of using space tools and working in similar environments to suited astronauts.

S

 * Serial manipulator an articulated robot or manipulator with a single series kinematic chain of actuators. c.f. parallel manipulator.
 * Service robots are machines that extend human capabilities.
 * Servo, a motor that moves to and maintains a set position under command, rather than continuously moving.
 * Servomechanism An automatic device that uses error-sensing negative feedback to correct the performance of a mechanism.
 * Single Point of Control The ability to operate the robot such that initiation or robot motion from one source of control is possible only from that source and cannot be overridden from another source.
 * Slow Speed Control A mode of robot motion control where the velocity of the robot is limited to allow persons sufficient time either to withdraw the hazardous motion or stop the robot.
 * Snake robot A robot component resembling a tentacle or elephant's trunk, where many small actuators are used to allow continuous curved motion of a robot component, with many degrees of freedom. This is usually applied to snake-arm robots, which use this as a flexible manipulator. A rarer application is the snakebot, where the entire robot is mobile and snake-like, so as to gain access through narrow spaces.

 * Stewart platform A movable platform using six linear actuators, hence also known as a Hexapod.
 * Subsumption architecture A robot architecture that uses a modular, bottom-up design beginning with the least complex behavioral tasks.

 * Swarm robotics involve large numbers of mostly simple physical robots. Their actions may seek to incorporate emergent behavior observed in social insects (swarm intelligence).
 * Synchro

T

 * Teach Mode The control state that allows the generation and storage of positional data points effected by moving the robot arm through a path of intended motions.
 * Three Laws of Robotics, coined by the science fiction author Isaac Asimov, one of the first serious considerations of the ethics and robopsychological aspects of robotics.

W

 * Waldo, a short story by Robert Heinlein, that gave its name to a popular nickname for remote manipulators.
 * Walking robot, a robot capable of locomotion by walking. Owing to the difficulties of balance, two-legged walking robots have so far been rare and most walking robots have used insect-like multilegged walking gaits.

Z

 * Zero Moment Point. Zero Moment Point is a concept related with dynamics and control of legged locomotion, e.g., for humanoid robots. It specifies the point with respect to which dynamic reaction force at the contact of the foot with the ground does not produce any moment, i.e. the point where total inertia force equals 0 (zero).
 * ZMP. See Zero Moment Point.
