What is a Robot? A robot is a mechanical device, it is programmable, and controllable by a computer or by a human. It is usually a system, which, by its appearance or movements, conveys a sense that it has intent of its own. Coroware Kuka Robosoft Robotics Connection Mindstorm NXT iRobot

Robot Body The component that holds or connect other components through links and joints:

Types of Joints A ball joint allows rotation around x, y, and z axes, A hinge joint allows rotation around one axis, A slider joint, which allows movement along one axis. A Spring joint, which allows free movement along all axes. Source: Combined

Robot Effectors Component to accomplish some desired physical functions Examples: – Hands/Claws – Legs – Wheels – Cage – Tools

Robot Actuators (Muscle) Actuators are the “muscles” of the robot. These can be electric motors, hydraulic systems, pneumatic systems, or any other system that can apply forces to the system. Electric Hydraulic systems Pneumatic

Sensor Classes: Ranging sensors  Ranging sensors, such as  sonar,  ultrasonic,  IR, and  laser sensors:  These sensors return the distance to the object.  They typically have two lens (eyes). One sends out a light beam and the other receives the reflected beam.  By measuring the time and angle of reflected beam, the sensors can measure the distance to the object Distance = speed x time Sensors derive information from environment.

Sensor Classes: Other Sensors There are many types of sensors  Contact (touch) sensor: A signal is generated when touched  Compass (magnetic) sensor / Gyro senor (rotation)  GPS (Global Positioning System)  Color sensor: return different value for different colors  Temperature sensor Return the temperature  Cameras and microphones  Vehicle accelerometer sensor  Vehicle tire pressure sensor  …

Example: NXT Robot Body, Sensors and Effectors

Example: NXT Robot Body, Sensors and Effector Sonar Sensor Touch Sensor Actuator: Motor Effector While (true) { if touch sensor pressed Trigger the motor; else if sonar distance < 3 feet { while sonar distance < 5 { } Trigger the motor; } Image from:
