Humanoid

Kojiro mimics the human body and can handle more complex movements.

Kojiro is a humanoid which is built by the University of Tokyo’s JSK Robotics Laboratory.

Kojiro  musculoskeletal humanoid robot has a detailed musculoskeletal system built to mimic the human body.

To develop control algorithms for Kojiro, the JSK team is using an iterative learning process. This kind of system has lots of nonlinearities and is hard to model precisely.

The main drawback of using a musculoskeletal system is that controlling the robot’s body is difficult. For balance, the robot uses three gyros and a three-axis accelerometer on its head. To keep track of its posture and limb positions, they embedded joint angle sensors on spherical joints and six-axis force sensors on the ankles. To make the robot safer, the researchers built its body using mostly light and flexible materials. The results are transmitted to a computer and displayed on a control screen developed by Takanishi. A driver circuit board automatically adjusts the current fed to the motors based on temperature measurements.

Each motor unit has a rotary encoder, tension sensor, and current and temperature sensing circuit. Its brushless motors are quite small but can deliver a substantial 40 watts of output power. These tendon-muscle structures — Kojiro has about 100 of them — work together to give the robot some 60 degrees of freedom, or much more than could be achieved with motorized rotary joints.

XPERO project Research on technology to understand human being [Degrees of freedom]

XPERO’s A.I. is stored in Nao, an autonomous, programmable and medium-sized humanoid robot. This video demonstrates and explains very simple the complexity of the science declared A.I. (artificial intelligence).

4. Degrees of freedom (“…from the data obtained this way, he builds a model that describes what we know as degrees of freedom.”)

A robot explores his environment and learns from his experiences

This is about autonomous robot scholarship by experimentation and gaining insights of the world. The robot has no particular goal but to gain knowledge of as much as possible by forecast and executing experiments in his environment and of course from its knowledge-beginning obtained data. The robot learns relations between its measures and observations.

Degree-Of-Freedom

Conscious that the robot is gifted to move the boxes, it wonders how far it is capable to impulse them. It chooses a box and begins to push it in one command awaiting the box hits a wall. Surprised that the box is out of the blue unmovable, he tries just about it in new directions and succeeds to slide the box down the wall, in anticipation of he reaches a corner.

From the data obtained this way, he builds a model that describes what we know as ‘degrees of freedom’ as shown in the picture

The synth-playing robot (1984)

Idea via SynthGear “The synth-playing robot”

“Biped robot that balances dynamically using a human-like walking motion.”

Idea to this post an more videos via FastCompany

Boston Dynamics is a small engineering and robotics firm spun off from MIT in 1982. According to its own Web site it “builds advanced robots with remarkable behavior: mobility, agility, dexterity and speed.” Those parameters sound kinda military-like for a reason: BD has worked with DARPA, the Army, the Navy, and Marine Corps, as well as the more innocuous-sounding Sony. Their current starting lineup:Biped robot that balances dynamically using a human-like walking motion.

Can it be more realistic (scary)?
