Last weekend, 17 teams came to Homestead, Fla., to participate in the US Defense Advanced Research Projects Agency's DARPA Robotics Challenge Trials. The competition has eight missions for contestants to test robots that can carry out rescue work after natural disasters, including driving cars, crossing rough terrain, climbing ladders, removing debris, opening a series of portals, drilling holes in walls, opening Valves and rolled up hoses, etc. Teams participating in the competition can design their own robots or write software that runs on the Boston Dynamics Atlas robot. For some of the world's most advanced robots, these tasks seem simple. However, when doing these tasks, only a few teams can get full marks in any one project; at the same time, despite spending more than two hours to try, there are three teams that get zero points. After the audience witnessed many failures and restarts, the final winner was the HRP-2 humanoid robot produced by the Japanese company Schaft, which was acquired by Google earlier this year. The HRP-2 won't be surprising, as Schaft released the video ahead of the game, showing that the robot can do all of the above. The score for this contest was 32 points, and Schaft scored an incredible 27 points. The runner-up came from the Florida Institute for Human and Machine Cognition, a non-profit research institution whose final score was 20 points. Carnegie Mellon University's CHIMP robot won the third place with a total score of 18 points. The university's participating robots weigh 400 pounds (about 181 kilograms) and have a bright red color with a wingspan of 10 feet. "3 meters" of the "wings". Other winners include MIT, NASA's Jet Propulsion Labs, defense industry giant Lockheed Martin, Worcester Polytechnic Institute, and Headquartered in Texas, TRACLabs Laboratory. The finals will be held next year, and these contestants will gather at that time to compete for a $2 million prize. Here are some of the robots that appeared in this contest: Reading Braille: Braille Instructions,Braille Alphabet,Braille Printing,Braille Packaging Box Shanghai Caide Printing Co.,Ltd. , https://www.caidelabels.com
1. Familiarize yourself with the Braille alphabet, which consists of six dots arranged in two columns of three dots each. Each dot or combination of dots represents a different letter, number, punctuation mark, or special symbol.
2. Place your fingertips lightly on the Braille text, typically on a page or surface made specifically for Braille.
3. Feel the dots with your fingertips and identify the patterns to determine the corresponding letters, numbers, or symbols.
4. Move your fingertips systematically across the Braille text, reading from left to right and top to bottom, just like reading regular text.
Writing Braille:
1. Learn the Braille alphabet and practice writing each letter, number, punctuation mark, and special symbol.
2. Use a Braille slate and stylus, which is a tool specifically designed for writing Braille. The slate has rectangular openings to hold the paper, and the stylus is used to press the dots onto the paper through the openings.
3. Place a piece of Braille paper or cardstock into the slate, ensuring it is aligned properly.
4. Hold the stylus like a pen or pencil and press the appropriate dots onto the paper, one at a time, following the Braille alphabet.
5. Lift the stylus after each dot is pressed to avoid smudging or blending the dots together.
6. Continue writing the desired text, moving from left to right and top to bottom on the paper.
7. Review your writing by feeling the dots with your fingertips to ensure accuracy.
It is important to note that learning Braille may require time and practice, as it is a tactile skill that requires the ability to distinguish between the different dot patterns. However, with dedication and persistence, individuals can become proficient in reading and writing Braille.
