Robot Dancer HRP-4C – development of scientists from Japan, the Japanese National Institute of Science and Technology AIST (National Institute of Advanced Industrial Science and Technology).

Specialists from AIST continue to improve their abilities and pretty soon a robot was SINGING.

The next step was teaching robot to dance,and that was implemented by using an animation package Choreonoid (a combination of Choreography and Humanoid). 

This software generates movements with same principle as the traditional programs for three-dimensional graphics – the user sets the key provisions of the object, and the program calculates the interpolation between them.

The body of HRP-4C have 30 motors and 8 more, small motors, built into the head of the robot. Thanks to them, the robot can express various emotions.

Development of robotic androids are engaged in just one decade and has already achieved considerable success. And it is very possible that after another decade androids will work unthinkable jobs for us.

Surfers’ skills are tested not only in their ability to control their board in challenging conditions and/or catch and ride challenging waves, but by their ability to execute maneuvers such as turning and carving. Some of the common turns have become recognizable tricks such as the cutback (turning back toward the breaking part of the wave), the floater (riding on the top of the breaking curl of the wave), and off the lip (banking off the top of the wave). A newer addition to surfing is the progression of the air where a surfer propels themselves off the wave and re-enters. Some of these maneuvers are executed to extreme degrees, as with off-the-lips where a surfer over-rotates his turn and re-enters backward, or airs done in the same fashion, recovering either with re-rotation or continuing the over-rotation to come out with his nose forward again.
When tube riding, the surfer maneuvers into a position where the wave curls over the top of him or her, forming a tube (or barrel), with the rider inside the hollow portion of the wave. This difficult and sometimes dangerous procedure is arguably the most coveted and sought-after goal in surfing.

Hanging Ten and Hanging Five are moves usually specific to longboarding. Hanging Ten refers to having both feet on the front end of the board with all of the surfer’s toes off the edge, also known as noseriding. Hanging Five is having just one foot near the front, toes off the edge. Hanging Ten was first made famous by James (Rip) Carman from the early Californian surfing beaches.
