What Is an Articulated Robot?

The reason why walking robots attract people is not their practicality, but because of their novelty. After all, the design of such robots is more difficult. With the rapid development of science and technology, scientists have developed various robots, and have made great achievements in imitating animals, but there is still a certain gap in the development of robots like humans who can walk freely. The latest computer simulations from the University of Vermont show that, similar to animal evolution, robots will gradually evolve to improve their walking capabilities.

Reason for attraction

Novelty

In August 2011, a laboratory at the University of Michigan in the United States developed a robot that can run like a human, bringing the agility and efficiency of a two-legged robot to a new level. This robot is called "MABEL" and can reach a maximum speed of about 11 kilometers per hour. It is believed to be the fastest two-legged knee robot in the world.

Since the 1990s, scientists have been focusing on one area-"Passive Dynamics", aerospace engineer Tad McGill

According to the British "Daily Mail" reported on March 6, the United States Boston Dynamics has recently developed

by

"Jam" robot

A robot whose shape can be changed. When needed, it can switch between solids and liquids, enter the enemy's room through door slits or small holes, and perform tasks.

"Ostrich" robot

An ostrich-like robot. It has two legs and can run fast on the ground. It can accelerate from standstill to 32 km / h in 15 seconds.

On November 1, 2011, according to the British "Daily Mail" website report, a two-legged humanoid military robot named "Pet Man" swings arms and steps like a soldier, and can also do jumping and push-ups, etc. Maneuver without losing balance while doing these exercises. The company claims that "Pet Man" is the first robot that is similar in size and size to a human and can walk like a human, and it can travel at speeds of up to 4.4 miles per hour. Part of the funding for this robot was provided by the US Department of Defense's Advanced Research Projects Agency.

Boston Dynamics also designed an "Atlas" robot, which has a human torso, two arms and two legs, but no head. It can walk on rugged terrain and can be climbed by hand in special cases. . The company hopes that the Cheetah robot will be more advanced than the previous "Pittman" robot. It is reported that the Pittman robot can be used to test chemical weapons, thereby protecting soldiers and walking up to 3 mph in an upright manner.

In July 2010, Cornell University's latest development of a "Ranger" robot, which can walk 23 kilometers in 11 hours, built

Commando Robot

Set an unofficial world record. On July 6, the robot "commando" walked 108.5 laps around the track and field track of Cornell University's Barton Stadium, each circa 212 meters. This robot walked a total of 70,000 steps from start to battery exhaustion. The entire process was only remotely controlled by researchers nearby. It is reported that the previous world record was created by the Boston Dynamics "Big Dog" robot and completed a total of 20.59 kilometers. Andy Ruina, a professor of theory and applied mechanics at Cornell University, led several engineering college students to complete the research. Earlier, students at the Ruiner Lab created a robot walking record in April 2008, when the "commando" walked 9 kilometers.

This robot looks like a tall saw frame, and its gait is like a person with a cane. It has 4 support legs and no "knee" structure. Unlike other walking robots that use an engine to control movement, the "commando" robot uses gravity and power to promote the legs to move forward. It behaves more flexibly and is comparable to human walking to a certain extent. Ruiner said that through this robot walking experiment, it will not only help to promote the development of advanced robots, but also help these college students understand the principles of robot walking more deeply. These principles and information can be applied to human prosthetic research and disabled limb recovery. And help improve people's athletic ability. ^[6]
