Using a learning algorithm, Italian researchers taught a child-like humanoid robot archery, even outfitting it with a spectacular headdress to celebrate its new skill.
Petar Kormushev, Sylvain Calinon and Ryo Saegusa of the Italian Institute of Technology developed an algorithm called "Archer," for Augmented Reward Chained Regression. The iCub robot is taught how to hold the bow and arrow, but then learns by itself how to aim and shoot the arrow so it hits the center of a target.
Watch it learn below.
The researchers say this type of learning algorithm would be preferable to even their own reinforcement learning techniques, which require more input from humans. Kormushev et. al chose archery because of its complexity, requiring coordinated visual processing, the use of both hands and external tools.
The team used an iCub, a small humanoid robot designed to look like a 3-year-old child. It was developed by a consortium of European universities with the goal of mimicking and understanding cognition, according to Technology Review. It has several physical and visual sensors, and "Archer" takes advantage of them to provide more feedback than other learning algorithms, the researchers say.
The team will present their findings with the archery learning algorithm at the Humanoids 2010 conference in December.
First the bow and arrow, next the paintball gun, then the handgun...
Guns would be much easier than bows. Theyre just point and shoot. Their flight paths are consistent and predictable, allowing a program to reproduce shots without difficulty. However, for an autonomous robot to perform the complicated movement involved in using a bow, and then learn by itself to shoot it accurately is a great achievement. This research wont lead to guns, it will lead to things like cleaning, carrying, and performing other human tasks, without constant input from a programmer. Not everything having to do with robots will end up in Armageddon. iRobot was a movie. This is real life.
I believe you are mistaking my joke for the very thing I was making fun of.
Although, it was very thoughtful of you to write such a long comment.
A feather headdress? Really?
Using a learning algorithm, researchers taught a child-like humanoid robot human dismemberment, even outfitting it with a pair of razor sharp claws to celebrate its new skill.
So how long do you think it will be before someone programs a bot to target another person, a hitbot
Worst idea to program a robot into how to "learn"... this isn't learning, this is programing for compensation
When did Popsci commenters get as annoying and ignorant as Youtubers?
I'm looking forward to the cook bot! How nice would that be to have a robot chef in your kitchen?
An American archer went to Japan to improve his skills in archery. The teacher could hit the bulls eye blindfolded. How is that possible? It turns out that the Japanese archer would project his spiritual third eye to the target and look back at himself aiming the bow and arrow. This technique can also be used to project the third eye, which responds to mental commands such as "scan right", to view objects tens of thousands of miles away. It also works at a hundred thousand light years to project to planets on the edge of the galaxy. On one side of the planet you see just black space and on the other side you see the entire Milky Way with all its beautiful stars.
