The lesson movie that Mr. Mark · Laybert of Boston · Dynamics did at the alma mater's MIT is open now

Robot development companyBoston · DynamicsMark Lei Bert, CEO, took classes at the alma mater's MIT. I will explain to students about robot engineering aimed at by Boston · Dynamics.

Laybert used to learn psychology and cognitive science while studying at MIT, but when he saw experiments of grasping thousands of things on the desk with the robot arm at the AI ​​research center I felt "this is the way to go", he said that he turned into a world of robot engineering. After that, he abandoned Professor MIT and launched Boston Dynamics, and developed numerous robots. We aim to develop robots with exercise capacity beyond humans and animals.


It was born at the end of the 10 years research from entrepreneurship "BigDog"


Physics research is indispensable for realizing the big goal of dynamic and stable operation. In the development of BigDog capable of carrying 400 pounds (about 180 kilograms) of loads, experiments were conducted everywhere throughout the United States.


In Virginia, it pounds the bushes ......


In Boston, I went through deep snow and I heard that I got stability that I could not fall down even if I was kicked.


List of robots that Boston · Dynamics has developed.


In this lecture, I will mention about the latest four robots. In each robot,Acquired by Google in 2013It seems to have been developed afterwards.


According to Laybert, "SpotIt was said that there were quite a lot of things to learn from development. By improving the complicated combination of controllers to simpler and more compact one, it seems that technological evolution that has shifted from rough movements to more sophisticated control can be described as innovative.


The robot developed by Boston · Dynamics including Spot is never made for the purpose of doing any specific action. The goal is to change the correspondence according to what you want to do.


For example,SpotMiniTests are being carried out as "delivery robots" that deliver packages to homes, but because the buildings of the addressees and the layout of the garden are all different, the applied force that can cope with various situations in the real world flexibly to the robot It is required. As a result of collecting data and making improvements and adjustments, it is said that delivery can be done without trouble at a rate of 70% to 80%.


Most people believe that "robots" as hardware including sensors etc. interact with computers with respect to robotics engineering. However, Laybert believes that "real world" will be added as a target for robots to interact with. For example, when timing such as when releasing energized energy to spring, the optimum value changes according to the real world situation, it seems that "the real world is instructing and instructing the robot", the computer, the robot, the real world We believe that cooperation is required.


In addition, Lauret said that in Boston Dynamics, "Build it" "Break it" "Fix it" approach is adopted. From the process of "making, breaking and repairing", the technology will increase at a fast speed.


Robber researchers from acquaintance Laybert say that some people are afraid to be afraid of breaking the work (robot) they made, but Boston Dynamics has a technician who can quickly repair even if it breaks. Actually moving the robot in the physical world seems to be able to learn a lot of things, which means that it can only be improved quickly by this. Laybert says, "Make and turn the breaking loop as soon as possible, so that you can reach the goal quickly by doing so."


A robot that made it so that it can move forward while avoiding objects, but does not advance towards trees. According to Laybert CEO, "I fell in love with trees".


A robot that ran at a tremendous speed, rushed to the old BMW and rolled over.


The BMW seems to have been a car just recently delivered by a Boston Dynamics engineer, and Raybert said he paid a repair charge of $ 5,000 (about 530,000 yen).


Robot development has realistic issues requiring a short-term perspective and issues requiring a long-term perspective.


For example, although the delivery robot that has already been described is a robot that requires a short-term vision, it is a state where completion of automatic driving car technology is awaited for practical use. With tags with automatic driving cars, delivery robotization is expected to be realized. In addition, it is said that most of "logistics" in which as many as 1 trillion boxes can be delivered to various places is done by human beings, and there is a big opportunity to let the robot help this.


Laybert believes that elderly care and support for people with disabilities will become the ultimate goal for robot technology. "In my case, I have no choice but to expect from a child for nursing care after age, but everyone can expect support from a robot, and if you want, you will be able to care for a robot."


Again, about a specific robot. Improve 180 pounds (about 80 kilograms) SpotSpotMini"Weight was reduced to 60 pounds (about 27 kg).


Under the crotch of Spot, SpotMini has succeeded in miniaturization enough to escape. Besides SpotMini equipped with a 500 Wh battery, the evolution of the battery is the key to robot technology. Robots are expected to evolve further with the advent of batteries with higher safety and reliability and larger capacity.


Laybert said he wants to make SpotMini a platform like Android. On Android smartphone terminals are developed by each manufacturer, applications are developed from developers, and they function as hardware / software platforms. It seems that he wishes to develop SpotMini as a platform to develop "my robot" by various developers participating and enhancing technology.


In the classroom that became the venue, a demonstration was carried out in which SpotMini autonomously walks in front of students of MIT.


Next, "Humanoid robot"Atlas". Originally it was a robot developed for the robot contest organized by DARPA.


Compared to the DARPA challenge, most of the parts were improved, and light weight, compactness and high rigidity were succeeded.


We have succeeded in slimming down and weight saving by power unit with built-in original hydraulic system. In addition, it seems that it was made simple by outputting the parts composed of many parts with a 3D printer.


Weight can be reduced from 375 pounds (about 170 kilograms) when participating in the DARPA Challenge to 165 pounds (about 75 kilograms) and succeeded in weight reduction to the same level as humans. AtlasSuccess in the bad worldWe have the ability to exercise so much.


In the end is a robot with its own design that is not restricted by the frame of human type "Handle"


Atlas's joints were 28, while Handle has 10 greatly reduced range of motion. However, we have succeeded in having overwhelming exercise ability which can not be reached by a humanoid robot which can move freely with a wheel and jump and lightly carry heavy objects. Atlas, which has a small footprint and can freely carry heavy objects, says Laybert, who can support humans at the logistics site.


Here, I introduce 18 engineers who are enrolled at MIT from Boston · Dynamics. "They are all happy," an invitation to Boston Dynamics was held for MIT students.


Finally about robot development. "You know, I was in a professorial position at MIT and Carnegie Mellon University," he told his own background, CEO Raybert talked about how many papers he would like to write in his professorial days, how many researchers He said he was competing for being cited in the paper. Raybaard, who has become a businessman after launching Boston Dynamics, is now competing for the number of views on YouTube, not the number of papers, but competing for the number of mischievous movie uploads, not the citation number of thesis.


Introducing movies of Akihabara, Los Angeles, Holland and Appalachia uploaded to YouTube.


I praised himself that he was uploading 28 mischievous movies and was doing the best work it was doing right now.
