The goal is to spark student interest in computer science as a career amid declining enrollment nationwide.\u003C\/p\u003E\u003Cp\u003E\u201cClassic introductory computer science courses are dry,\u201d says Tucker Balch, director of the new Institute for Personal Robots in Education (IPRE) based at Georgia Tech. \u201cThe most exciting thing students do is print out a prime number. But if you have robots you can drive around and that makes computer science exciting and fun.\u201d\u003C\/p\u003E\u003Cp\u003EAs early as this fall, the $150 robot and a related textbook packaged together will be available in student bookstores at more than 50 U.S. universities, including Georgia State University and the University of Georgia. The program is being funded for three years with $1 million from Microsoft and another $1 million from the Georgia Tech College of Computing and Bryn Mawr.\u003C\/p\u003E\u003Cp\u003EStudents taking the introductory computer science class first learn how to drive their robots in a straight line for 12 inches before making a right turn. That means they have learned how to write two lines of code. Then they discover that by executing these two lines of code three times, the robot moves along the path of a square.\u003C\/p\u003E\u003Cp\u003E\u201cSo now they have learned the first important thing in computer science: A program is a set of instructions that are executed in a certain order,\u201d explains Balch, an associate professor in the College of Computing. \u201cYou don\u2019t have to write the code four times; you do a loop to make it do this thing four times. Now, they have learned the second most fundamental thing. The whole time this learning is embedded in this interesting physical thing that moves around.\u201d\u003C\/p\u003E\u003Cp\u003EOther universities are using robots teach computer science, Balch notes, but he believes Georgia Tech\u2019s approach is better for two primary reasons. Elsewhere, students typically write a program on their computers, download it and run it on a robot. But if the robot fails to do what it\u2019s supposed to do, the student has no idea where the program failed.\u003C\/p\u003E\u003Cp\u003E\u201cWith our concept, the program runs on a laptop, and the robot is the peripheral,\u201d Balch explains. \u201cThe robot sends information to the laptop from its sensors. We had to create our own robots to work this way.\u201d\u003C\/p\u003E\u003Cp\u003EThe other big difference between Georgia Tech\u2019s class and others using robots is that every Tech student gets his or her own personal robot. Elsewhere, students use expensive robots in a lab.\u003C\/p\u003E\u003Cp\u003EGeorgia Tech and Bryn Mawr are able to give students their own robot by using an existing commercial robot called Scribbler\u2122, which is sold to the universities at a discounted rate of about $55 each by Parallax. Researchers have added wireless connectivity to it, bumping the cost to $150 each. Balch believes that cost will eventually drop.\u003C\/p\u003E\u003Cp\u003E\u201cIt\u2019s a robust robot,\u201d Balch says. \u201cStudents have dropped them on the ground and run them off desks, but it doesn\u2019t stop them.\u201d\u003C\/p\u003E\u003Cp\u003EAs more students at Georgia Tech and elsewhere use the Scribbler and textbook in introductory computer science classes, Balch and his colleagues will gather feedback and use it to improve the curriculum, he says. Eventually, they want to make the robots available for use in middle and high schools to spur interest in computer science at that level.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"College students how have a chance to learn fundamental, often-abstract computer science concepts in a hands-on way using small, two-wheeled personal robots that move and interact with each other."}],"uid":"28152","created_gmt":"2014-11-11 16:45:31","changed_gmt":"2016-10-08 03:17:30","author":"Claire Labanz","boilerplate_text":"","field_publication":"","field_article_url":"","dateline":{"date":"2007-04-08T00:00:00-04:00","iso_date":"2007-04-08T00:00:00-04:00","tz":"America\/New_York"},"extras":[],"groups":[{"id":"1188","name":"Research Horizons"}],"categories":[{"id":"42941","name":"Art Research"}],"keywords":[{"id":"109261","name":"Winter\/Spring 2007 Issue"}],"core_research_areas":[{"id":"39521","name":"Robotics"}],"news_room_topics":[],"event_categories":[],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003E\u003Cstrong\u003EResearch News\u2028\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EGeorgia Institute of Technology\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003E\u2028177 North Avenue\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003E\u2028Atlanta, Georgia\u0026nbsp; 30332-0181 \u0026nbsp;USA\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EMedia Relations Contacts:\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EJohn Toon\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003E\u2028404-894-6986\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003E\u2028\u003C\/strong\u003E\u003Ca href=\u0022mailto:jtoon@gatech.edu\u0022\u003E\u003Cstrong\u003Ejtoon@gatech.edu\u003C\/strong\u003E\u003C\/a\u003E\u003Cstrong\u003E\u2028\u2028\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EBrett Israel\u2028\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003E404-385-1933\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003E\u2028\u003C\/strong\u003E\u003Ca href=\u0022mailto:brett.israel@comm.gatech.edu\u0022\u003E\u003Cstrong\u003Ebrett.israel@comm.gatech.edu\u003C\/strong\u003E\u003C\/a\u003E\u003C\/p\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
