  9. Solar Energy & the Environment • Solar energy produces no air or water pollution and no greenhouse gases • Manufacturing process of photovoltaic cells (PV) – use toxic materials and chemicals • Large solar thermal power plants – can be harmful to desert ecosystems • Solar thermal systems - use potentially hazardous fluids ( • Concentrating solar systems - water for regular cleaning/cooling Source: http://www.eia.gov/kids/energy.cfm?page=solar_home#solar_environment-basics

  12. What is a Robot? A robot is a device consisting of sensors, a body and Central Processing Unit (CPU) that together collect and respond to feedback in an autonomous way. What does all of this mean?

  13. Feedback The principle of feedback deals with changes in condition…then self correction.

  14. Sensors In order to detect changes and then send feedback a robot needs sensors. Sensors are small devices connected to the brain, or CPU, of the robot that tell the robot about the environment.

  15. Central Processing Unit (CPU) The Central Processing Unit, or CPU, receives and interprets electronic signals that come from the sensors. A CPU uses a series of transistors and circuits that mimic the function of a brain, sort of like a computer.

  16. Autonomous Behavior Autonomous means “self-directed,” autonomous behavior is behavior that happened in response to feedback. Autonomous behavior is not planned in advance but happens as a result of outside influences.

  17. Body The final part of the robot puzzle is the body. Without a body to physically react to feedback a robot is not a robot, it is more like a computer. The sensors send information to the robot’s CPU and the CPU then sends electronic signals to the robot’s actuators or motors. This system allows the robot to autonomously move and react to the environment.
