Before you begin the activities in this Learning Launcher, write down what you already know about robots and robotics. List three things you learned from the What You Should Know section. Choose the definition of robot that makes the most sense to you and explain the reasons for your choice. Take a video of your robot attempting a task. With the camera running, give a commentary of what worked and what didnt. Explain how you will improve the performance or fix a problem. Create a glossary of the vocabulary words associated with robots and robotics. Pay particular attention to the bold, italicized words in this Learning Launcher. Write a schematic drawing of one of your programs. Add comments to explain your intentions for the robot. Tell which of the Research Prototypes was a favorite and why.

Describe how you have used a Sense-Plan-Act sequence in a situation in your life. Creative Learning Systems What You Should Know There isnt a single definition of robot that is agreed upon and used world-wide. The International Organization for Standardization gives a definition of robot as "an automatically controlled, reprogrammable, multipurpose, manipulator programmable in three or more axes, which may be either fixed in place or mobile for use in industrial automation application. The Robotics Institute of America (RIA) uses a broader definition: a robot is a "re-programmable multi-functional manipulator designed to move materials, parts, tools, or specialized devices through variable programmed motions for the

performance of a variety of tasks". Creative Learning Systems What You Should Know Encyclopedia Britannica defines a robot as any automatically operated machine that replaces human effort, though it may not resemble human beings in appearance or perform functions in a humanlike manner. Generally speaking, we can say that a robot is a machine that can be programmed and/or respond to sensors. Creative Learning Systems

What You Should Know The word robot was first used in 1921 by Czech writer Karel Capek in his play R.U.R. Rossums Universal Robots. In Czech and many Slavic languages, the word robota means work, labor, drudgery or hard work. Isaac Asimov, a science fiction writer, first used the word robotics in 1941 to describe this field of study. Creative Learning Systems What You Should Know

The idea of automated machines or artificial helpers has been recorded since the early 1200s. Al-Jazari, a Muslim inventor, designed musical instruments that were programmable with wooden pegs. In the 1500s Leonardo da Vinci conceived an idea for a mechanical knight. In 1961, the first digitally operated and programmable robot, called the Unimate, was created to lift and stack hot pieces of metal from a die casting machine. Today, robots are used in commercial and in industrial settings

to do the work previously done by humans. In some cases, they are used because they can work more cheaply or with greater accuracy and reliability than humans. In other cases, they perform jobs that are too dirty, dangerous or boring for humans. Creative Learning Systems What You Should Know There are two main types of robots: general purpose autonomous and purpose-built. General purpose autonomous robots are designed to perform multiple tasks and to function independent of human control, using sensors, for example, to intelligently move through areas. They are often designed to mimic human behavior and may resemble humans in appearance and structure. They are therefore sometimes called humanoid robots.

Purpose-built robots are designed to perform a specific job or task. They may perform tasks that humans can do but with greater productivity, accuracy, or endurance. They may also perform dirty, dangerous or dull jobs which humans find undesirable. Creative Learning Systems What You Should Know Purpose-built robots are often seen in factories or businesses.

One type found in businesses is the automated guided vehicle (AGV) and is frequently used to carry medical supplies or documents in hospitals, or for mail delivery in large corporations. Robots are common in car factories, packaging facilities, and electronics manufacturing plants. In fact, in car factories, there is one robot for every ten human workers! Creative Learning Systems What You Should Know There are two aspects to consider when creating and trouble-shooting a robot construction and

programming. Construction refers to the mechanics of a robot - how it is made, how it can move, the types of built-in sensors it has, and other mechanical functions. Programming refers to the software instructions that define the tasks the robot will perform and how it will interpret and respond to sensory information. Creative Learning Systems Do It! Now that you know a little more about robots and robotics, lets get started building and programming your own robot!

Go to the Carnegie Mellon Robotics Engineering software on your computer and push Introduction. Push Quickstart and follow the Quickstart Sequence. Creative Learning Systems Do It! After you finish the Quickstart Sequence, proceed to the Using the Lessons menu item. Watch that clip.

Finally, view the Using the Programming Software segment. Navigate your way around the CD to familiarize yourself with the specifics of the NXT program and components. Creative Learning Systems Do It! Now you get to start building! Push the Basics button at the top of the screen and push the Building Instructions menu item in the left-hand side bar.

Click on the Taskbot button item and follow the instructions to build your robot. Creative Learning Systems Do It! Next, you need to program the robot! Push the Projects button at the top of the screen, and complete the Research Prototypes tasks by watching the video and performing the steps outlined. Do your best to complete the first four Research Prototype activities. If you have time, see if you can complete all six! Creative Learning Systems
