Toyota's Robot Quartet Band

The most talented instrument-playing robots out there just got an upgrade from Toyota's engineers, who also make some pretty good cars.

Toyota's robot quartet consists of Harry (trumpet), Dave (trumpet), Chuck (tuba), and Ritchie (drums). Songs played include: "The Theme of Lupin III", "Moonlight Serenade", "Stompin 'at the Savoy", and "A train to go".Honda's ASIMO may have picked up the baton to conduct an entire orchestra, but Toyota has just outperformed the little guy with its suite of robo-musicians. the part-wheeled, part-bipedal quartet recently performed a concert where they actually played a trumpet, tuba, drums, violin and trombone.

Awesome, but no passion. Just plain machine music. Music with no soul. They get all the notes and the right beat and stuff. It's a little too perfect but it doesn't have the feel or atmosphere of a real band. This video may be entertaining, but I hope that the efforts that go into making these robots aren't just for music, because I don't think that's the kind of thing robots should be doing.

Toyota Robot Violinist

Toyota have unveiled a new robot that can play the violin. Toyota's robot violinist has 17 computer-controlled joints in its arms and fingers, which allow it to hold the violin, gently draw the bow, and correctly press the strings against the fingerboard. In a recital held at a Toyota showroom in Tokyo on December 6, the 152-centimeter (5-ft) tall humanoid entertained guests with a rendition of "Pomp and Circumstance."

The rendition was note perfect, but was described by some as "stilted". "Over the next two to three years, we will put the robots to the test through trial applications and see what kind of business possibilities they present," Toyota president Katsuaki Watanabe told The Guardian.

Robotics will become a core business for Toyota by 2020. The company will unveil medical robots next year, and plans more advanced "partner robots" for domestic duties, nursing, healthcare and short-distance personal transport by 2010.

Toyota is a comparative newcomer in the robotics field compared to manufacturers such as Honda. Demand for robots is strong in Japan, particularly in the domestic and medical fields.

Robot Expresses Facial Emotions

MIT's Nexi Robot Expresses Facial Emotions
MDS robots, closer to us

Nexi is a MDS small humanoid robot, designed by MIT Media Lab's Personal Robotics Group, capable of expressing facial emotions much in the same way as humans do. MDS actually stands for 'Mobile/Dexterous/Social', meaning it can perform a multitude of tasks, by moving around on its dynamically self-balancing wheels, with its fully compatible arms that can grab and lift objects up to 4.5 kilograms in weight.

Nexi was specially designed to mimic human movements at roughly the same speed. The head and face were created by the Xitome Design and MIT. The neck mechanism has four degrees of freedom and its face is able to express emotions through an array of movable features, such as the eyes, mouth, eyebrows and so on.

Two CCD cameras placed inside each eye gives it binocular vision of its surroundings, while an Active 3D infrared camera and microphones located in the forehead allows it to make 3D maps of the environment in which it is placed. Nexi was build on a previous robot design created at the Laboratory of Perceptual Robotics UMASS Amherst, the uBot5 mobile manipulator robot, which also uses a two-wheel dynamically balanced system to move around.
Nexi's facial expressions

Nexi is powered by lithium-ion batteries and controlled by an onboard personal computer working on a Linux operating system.

According to its designers, "the purpose of this platform is to support research and education goals in a human-robot interaction, teaming, and social learning." Robots like Nexi could one day work alongside with people in their homes. However, before becoming commercially available, Nexi will be used for research into human-robot interactions.

MIT Media Lab's website also reveal that, aside Nexi, three other small humanoid robots were developed, each of them with a fair amount of mobility, dexterity and human-centric communication and interaction abiliies.
