Basic Robotics : Terminology android n "droid([a^]n"droid), A machine or automaton in the form of a human being. Possessing human features. n. An automaton that is created from biological materials and resembles a human being. Also called humanoid. ,[object Object],[object Object],[object Object]

Basic Robotics : Terminology Articulated - Jointed arm. End Effector - Device at the end of a robot arm that is used to grasp or engage objects. Degrees of freedom - In mechanics, degrees of freedom (DOF) are the set of independent displacements that specify completely the displaced or deformed position of the body or system. Robot - Mechanical device that performs human tasks, either automatically or by remote control. (From the Czech word robota.) BEAM Robotics -The word "beam" in BEAM robotics is an acronym for B iology, E lectronics, A esthetics, and M echanics. This is a term that refers to a style of robotics that primarily uses simple analog circuits, such as comparators, instead of a microprocessor for simplicity in design Telerobotics - Robot that is operated remotely.
