Andrew Chudzik has spent some time building a bumper on his team
High school students from east central Indiana competed, informally, with their robotics projects on Sunday. They were preparing for the 2008 FIRST (For Inspiration and Recognition of Science and Technology) Robotics Challenge.
“We are here just, you know, comparing the robotics to other robotics. You know, try to get as much done, fine tuning as possible,” Greigh Davis, president of team 829, said.

The robot uses IR sensors to sense the line, an array of 8 IR LEDs (Tx) and sensors (Rx), facing the ground has been used in this setup. The output of the sensors is an analog signal which depends on the amount of light reflected back, this analog signal is given to the comparator to produce 0s and 1s which are then fed to the
Why would you want to interface the Keyboard? The IBM keyboard can be a cheap alternative to a keyboard on a Microprocessor development system. Or maybe you want a remote terminal, just couple it with a LCD Module.
Maybe you have a RS-232 Barcode Scanner or other input devices, which you want to use with existing software which only allows you to key in numbers or letters. You could design yourself a little box to convert RS-232 into a Keyboard Transmission, making it transparent to the software.
An interfacing example is given showing the keyboard’s protocols in action. This interfacing example uses a 89s51 MCU to decode an IBM AT keyboard and output the ASCII equivalent of the key pressed at 9600 BPS.
Note that this page only deals with AT Keyboards. If you have any XT keyboards, you wish to interface, consider placing them in a museum. We will not deal with this type of keyboard in this document. XT Keyboards use a different protocol compared to the AT, thus code contained on this page will be incompatible.
PC Keyboard Theory
The IBM keyboard you most probably have sitting in front of you, sends scan codes to your computer. The scan codes tell your Keyboard Bios, what keys you have pressed or released. Take for example the ‘A’ Key. The ‘A’ key has a scan code of 1C (hex). When you press the ‘A’ key, your keyboard will send 1C down it’s serial line. If you are still holding it down, for longer than it’s typematic delay, another 1C will be sent. This keeps occurring until another key has been pressed, or if the ‘A’ key has been released.
Inspired by the excitement of last year
(Nanowerk News) We are now living in an era of global competition, which is based on scientific and technological strength. Growth of a country is driven by technological renewal and creativity. To follow this situation, Vietnam
Adept Technology, Inc , the leading provider of intelligent vision-guided robotics and global robotics services, today announced it will host its Adept Global Conference 2008 event at its corporate offices in Livermore, CA April 2-4, 2008. The automation conference will feature industry leaders, real-world case studies, live automation demonstrations and a chance to network with automation leaders. Speakers will include representatives from such manufacturers and industry experts as Great Lakes Cheese, Evergreen Solar, Pepperidge Farm, Covidien, Robotics Industry Association and Medical Design magazine.”We are very excited to be hosting this event which will give attendees the opportunity to learn about the latest trends and opportunities in robotics, meet with manufacturers and solution providers alike and view live demonstrations,” said John Dulchinos, president and chief operating officer for Adept Technology, Inc. “It will also be an excellent forum to connect with peers and some of the top U.S. manufacturers.”
Six months after being introduced to robotics, the kids at Public School 21 in Bedford-Stuyvesant have scored big.
They were named the top team in Brooklyn during the FIRST LEGO League robotics competition at Brooklyn Tech last month.
FIRST – For Inspiration and Recognition in Science and Technology – is a group that creates innovative ways to get youngsters interested in science, technology and engineering. And the LEGO company creates and markets the popular multicolored interlocking plastic bricks, and other toys.
“It’s unusual to win a top award the first time out,” said Norman Scott, a retired teacher who serves as contest liaison.
On Jan. 26, the PS 21 kids won a Team Spirit Award during the New York City FIRST LEGO League Championship, a citywide competition held at Riverbank State Park in Manhattan.
Teams from St. Clare Elementary School on Staten Island landed the competition’s top honors, the Champion’s Award. The school’s Transformers 2 Team will represent New York City at an international competition in Atlanta.
