MIT recently published a new video of its Mini Cheetah robots, small quadrupedal robots that can run, walk, jump, turn, and backflip.

At the end of the song they were supposed to skip in a circle, jump-turn twice and wave jazz hands at the gathered audience.

They'll soon be tempted by an endless selection of mounts and accessories that promise to capture on video what they feel with every jump, turn, and crash.

According to the International Skating Union (ISU), the organization that regulates the sport, judges are responsible for determining a technical score based on the quality of each "element" (a jump, turn, or other movement) performed, and a presentation score, based on the quality of the performance.

The "Pedal-Jump Turn" was originally developed on traditional racing skis.

A jump turn is a skiing technique used in steep, narrow areas - such as a couloir - that do not permit a full parallel or carving turn. Jump turns involve pole planting followed by a quick hop that reverses the skiers' direction.

Patrick Vallençant (June 9, 1946 in Lyon – March 28, 1989) was a French alpinist/skier and pioneer in ski mountaineering. He was a pioneer in ski mountaineering and leader of the French school of ski mountaineers. His motto was: "si tu tombes, tu meurs", translated as "you fall, you die". In addition to numerous first descents, he was responsible for the creation of the "Pedal- Jump Turn" and co-founded the Degré 7 ski apparel company.

To cope with skiing the steep terrain (greater than 50 degrees), Vallençant developed a new turning technique, known as the "Pedal-Jump Turn" (also "Pedal Hop Turn" and "Pedal Step Turn"). The technique involved pushing off from the uphill ski, away from the slope and completing a portion of turn's rotation while in the air and then landing back on the downhill ski. With the advent of parabolic skis, using the uphill ski to initiate a turn is now a common technique for carved turns and racing. The key difference is in carving or racing the skier is traveling much faster, the terrain is not as steep and there is no need for such a dramatic thrust off the slope.

In order to safely ski these mountains he developed a new technique to "jump turn" on very steep inclines. Normal jump turns would have accelerated the skier and thrown him too far down the mountain so, using long ski poles, Saudan turned by planting a ski pole downhill and, keeping his weight on both skis and leaning back on his heels, he lifted the ski tips up and swivelled them in an arc into the turn. These turns, rhythmically swivelling the skis in arcs left and right, he christened the windscreen wiper turns. He is an accomplished guide for heliskiing, one of the first European guides, along with Hans Gmoser, to exploit the Bugaboos in British Columbia in the 1970s, with waist deep powder snow (often 150,000 vertical feet per week or more).
