LEGO® Mindstorms™ Robotics Invention System (RIS) ™ is a programmable toy. The kit contains an assortment of blocks, pieces, sensors and motors that connect allowing the student to produce objects limited only by imagination. The unique piece of the Invention System is the programmable brick called the NXT that brings the model to life. The NXT is programmable from a PC using an infrared transmitter (provided in the kit). There is a simpler system, the Robotics Discovery Set, that also uses a brick, but this set is not programmable from a PC. (Patterson-McNeill and Binkerd)
By analyzing the facts and information, I believe that robotics is a useful and innovation technology, and robots are replacing human worker’s job. Therefore, as a high-school student, I will research and introduce how we are going to make a high-school level robot with LEGO NXT.

(Patterson-McNeill and Binkerd) Hiroshi Makino of Yamanashi University designed the Selective Compliant Articulated Robot Arm (SCARA) for assembly jobs in factories.(Robot Shop) I believe that everybody knows that the domain of robotics field right now is on industry. Most industry robots do not look like androids but more likely an arm. Selective Compliant Articulated Robot Arm (SCARA) is the principle use of robotics field and it is the most kinds of robots that we have now. Japanese made the first modern industry SCARA in the robotics history, and the robot arms are getting closer and closer to our life. The Sukhoi Su-35 (Russian: Сухой Су-35; NATO reporting name: Flanker-E)[N 1] is a designation for two separate, heavily-upgraded derivatives of theSu-27 'Flanker'. They are single-seat, twin-engine supermaneuverable multirole fighters, designed by Sukhoi and built by Komsomolsk-on-Amur Aircraft Production Association (KnAAPO). The first variant was designed during the 1980s, when Sukhoi was seeking to upgrade its high-performance Su-27, and was initially known as the Su-27M. Later re-designated Su-35, this derivative incorporated aerodynamic refinements to increase manoeuvrability, enhanced avionics, longer range, and a more powerful engine. The first Su-35 prototype, converted from a Su-27, made its maiden flight in June 1988. More than a dozen of these were built, some of which were used by the Russian Knights aerobatic demonstration team. The first Su-35 design was later modified into the Su-37, which possessed thrust-vectoring engines and was used as a technology demonstrator. A sole Su-35UB two-seat trainer was built in the late 1990s that strongly resembled the Su-30MK family. In 2003, Sukhoi embarked on a second modernization of the Su-27 to produce what the company calls a 4++ generation fighter that would serve as an interim fighter prior to the arrival of the Sukhoi PAK FA. This derivative, while omitting the canards and air brake, incorporates a reinforced airframe, improved avionics and radar, thrust-vectoring engines, and a reduced frontal radar signature. In 2008 the revamped variant, erroneously named the Su-35BM in the media, began its flight test programme that would involve four prototypes, one of which was lost in 2009. The Russian Air Force has ordered 48 production units, designated Su-35S, of the newly revamped Su-35. Both Su-35 models marketed to many countries, including Brazil, China, India, Indonesia, and South Korea, but so far have not attracted any export orders. Sukhoi originally projected that it would export more than 160 units of the second modernized Su-35 worldwide. The Lockheed Martin F-22 Raptor is a single-seat, twin-engine fifth-generation supersonic supermaneuverable fighter aircraft that uses stealth technology. It was designed primarily as an air superiority fighter, but has additional capabilities that include ground attack, electronic warfare, andsignals intelligence roles.[6] Lockheed Martin Aeronautics is the prime contractor and is responsible for the majority of the airframe, weapon systems and final assembly of the F-22. Program partner Boeing Defense, Space & Security provides the wings, aft fuselage, avionics integration, and training systems.
The aircraft was variously designated F-22 and F/A-22 prior to formally entering service in December 2005 as the F-22A. Despite a protracted development, the United States Air Force considers the F-22 a critical component of their tactical air power, and claims that the aircraft is unmatched by any known or projected fighter.[7] Lockheed Martin claims that the Raptor's combination of stealth, speed, agility, precision and situational awareness, combined with air-to-air and air-to-ground combat capabilities, makes it the best overall fighter in the world today.[8] Air Chief Marshal Angus Houston, former Chief of the Australian Defence Force, said in 2004 that the "F-22 will be the most outstanding fighter plane ever built."[9] The high cost of the aircraft, a lack of clear air-to-air missions because of delays in Russian and Chinese fighter programs, a ban on exports, and development of the cheaper and more versatile F-35 led to the end of F-22 production.[N 1] A final procurement tally of 187 operational aircraft was established in 2009;[11] the final F-22 rolled off the assembly line on 13 December 2011 during a ceremony at Dobbins Air Reserve Base.[12] Starting in 2010, the F-22 was plagued by oxygen system problems that contributed to a fatal crash. In 2011 the fleet was grounded for four months before resuming flight, reports of oxygen issues persisted.[13] In July 2012, the Air Force announced that the hypoxia-like symptoms experienced were caused by a faulty valve in the pilots' pressure vest; the valve was replaced and the filtration system also changed. The picture above that I made on 16 April indicated two exactly same function programs with two kinds of programming software. The left one is Bricx CC and the right one is LabVIEW. This is a follow line program. The logical translation of this program is determined the value of light sensor, if both are greater than 80, go straight, if left light sensor is below 48 then turn left, if right light sensor is below 48 then turn right.
I spend 2 minutes to type the language up, but dragging the icons cost me 7 minutes. That is why I believe that traditional programming is better than graphic programming. It is faster, more accuracy and more logical. From the research and compression, I believe that there is enough proof to prove this point. Programming is an important of robotics, therefore choosing good programming software is no doubt important, and I suggest everyone, which is on advanced level to use traditional language programming software instead of graphic programming software. The sign of a new subject taking place is the point that people starting to use the term of this subject, same thing with robotics. The purpose of the first imagination of robot is for replace human’s job. Robot have been seen as a machine that tougher than human since we start using this term, and it is also be seen as then smart machine that serve human.
Karel Capek used the word Robot in his 1921 play Rossum’s Universal Robots, derived from the Czech word robota, meaning "forces labor.” These Robots were created to replace man and, in their simplified form, as cheap labor. The second milestone of robotics is Asimov came up with a clue of laws of robotics in 1942. 1.A robot may not injure a human being or, through inaction, allow a human being to come to harm. 2.A robot must obey the orders given to it by human beings, except where such orders would conflict with the First Law. 3.A robot may not injure its own kind and defend its own kind unless it is interfering with the first or second rule.(Wikipedia) For preventing robots seizure control of the world, Asimov came up with the laws of robotics, so we would not get terminated by something we created. At the same time, robots could serve better for us. As we know, nowadays, the biggest market that robotics taking place is in industry. There is another milestone on robotics that I researched and I believe it is important to point it out is THE SCARA, which is the first industry robot. Hiroshi Makino of Yamanashi University designed the Selective Compliant Articulated Robot Arm (SCARA) for assembly jobs in factories.(Robot Shop) Most industry robots do not look like androids but more likely an arm. Selective Compliant Articulated Robot Arm (SCARA) is the principle use of robotics field and it is the most kinds of robots that we have now. Japanese made the first modern industry SCARA in the robotics history, and the robot arms are getting closer and closer to our life. Robots are similar to human somehow, because they have strong bodies and at the same time, they have their own mind. However, the difference between human mind and robot mind is that humans think by themselves, robots think by the program that humans put on it. Therefore, programming is one of the most important parts of building a high-school level robot. By researching I find out that traditional language programming is more advanced that graphic programming. Here is the program of Limo, a line follower program. The logic of this program is identify the grayscale and follow the black line. Programming will not be finish in on time, but on of that necessary step of programming is testing.
The topic robotics has been around me for 7 years, I treated this subject as my love and my future. My robotics career can be conclude in 4 numbers, 7 2 2 99+, which is 7 years career, Won Beijing FLL champion twice, Created 2 robotics teams and have over 99 robotics products. I believe most people here are sure about the reason why I choice Robotics to be my project topic, which is that I have been doing robotics for 7 years and that is the subject that I love.

Lego Mindstorm program has begun for 16 years, and I am honor to be involved in 7 years with it. I remember the beginning of my robotics journey. I was 9 years old in 4th grade, by interested in a chance for traveling that school provided for robotics team, I started my journey of robotics. I still remember the first time I walked in that room, It just feel like I opened a new door in my life, a magic door to the haven of robotics technology.
The first robot I have been ever worked on is Lego RCX. It was around 2007, The 2nd generation was not fully apply yet. I worked on it 5 to 6 hours a day. That was a lot of work for a 4th grade little child. But I tried my best with it. I follow the step, Design, Construction, Programming and testing. As the beginning of the third quarter. As the ending of the 2013-2014 academic year. At this point, everything is so important for me especially my academic. I have just finished my presentation for all the wife of FUMA trustees, The presentation went very well, everybody was shocked by the performance of my robot. Next step for my robotics team is to training new guy and get them ready for next year.
For my presentation, I already placed a faculty appointment on 12th May with LTC. Meunch. I will start working on it on Monday and I believe that by working hard for a week, I will have a good presentation in front of everybody. About the whole project, I am very proud of it, I have done a lot of work on this project and I paid a lot of time on it. When a person ask me how was my class, I always tell them that it is a hard class with a lot of work but I truly enjoy it. It is the class that did most affection on me through my whole life. I wish I can work very hard and get an A. I have been noticed that Lego group just published their new generation robot EV3 last year. I am interested in this robot and I think that I am going to get a set of EV3 for future study and researching. By researching the detail of EV3, I found out that EV3 have been improved a lot from NXT. In the new set, there is a new servo motor that is medium size and strong power. They also added a DC motor in the set. I believe that there are way more choice of selecting motors, then there is more chice on construction. I finish my mid term exam pretty well today, and I have just finished my video for the FUMA blue devil Robotics team. I have been working on the resubmit work for whole CQ and I hope it will go well tomorrow on grading. And I also have a very important presentation at 10:45 in Library Classroom 1 about robotics. I wish that it will goes well. The biggest change from the Lego Mindstorms NXT and NXT 2.0 to EV3 series is the technology improvement of the programmable brick. The main processor of the NXT was an ARM7-based microcontroller, whereas the EV3 has an ARM9-based processor running Linux. A USB connector and Micro SD slot (up to 32GB) are new to the EV3. It comes with 5 models: EV3RSTORM, GRIPP3R, R3PTAR, SPIK3R, and TRACK3R. Lego has also announced that they will release instructions online to build 12 additional models from the set; ROBODOZ3R, BANNER PRINT3R, EV3MEG, BOBB3E, MR-B3AM, RAC3 TRUCK, KRAZ3, EV3D4, EL3CTRIC GUITAR, DINOR3X, WACK3M, and EV3GAME.[2]
The EV3 Home (31313) set consists of: 1 EV3 programmable brick, 2 Large Motors, 1 Medium Motor, 1 Touch Sensor, 1 Colour Sensor, 1 Infrared Sensor, 1 Remote Control, cables, USB cable, and 585 TECHNIC elements.() [2] The Education EV3 Core Set (45544) set consists of: 1 EV3 programmable brick, 2 Large Motors, 1 Medium Motor, 2 Touch Sensors, 1 Colour Sensor, 1 Gyroscopic Sensor, 1 Ultrasonic Sensor, cables, USB cable, 1 Rechargeable battery and many TECHNIC elements. [2] There is also an education set for the EV3 like the NXT. The core set contains 541 Lego elements including the EV3 brick, 2 large motors, 1 medium motor, an ultrasonic sensor, a pair of touch sensors, a gyro sensor and a colour sensor. The expansion set, which could be bought separately, contains 853 Lego elements. However, these two sets combined aren't capable to build most robots of the retail set unlike the education set of the NXT when the base set and the resource set can be combined to build any retail robots. The set is released 1 month earlier than the retail set, therefore it was released on August 1 2013. Robots that can be built by the core set itself are the EV3 educator robot, the GyroBoy, the Colour Sorter, the Puppy and the Robot Arm H25. Robots that can be built with the expansion set are the Tank Bot, the Znap, the Stair Climber, the Elephant and a remote control. Another robot that can be built with a pair of core set and an expansion set is the Spinner Factory.(Wikipedia) |
