A legged running robot for XMas


The best shotgun chroma keying algorithm still had a hard time isolating the path in the right lighting, so wasn't convinced making a new board would work. The sun is so low in winter, it makes a lot more shadows, revealing more problems in machine vision. It was back to more notes on robot dogs.

In the old days, it was a tradition to stump Santa by wanting what wouldn't exist for another 30 years: LED TV screens, quad copters, watch TV's. Now the tradition continues. Despite Boston Dynamics introducing a robot that could run 3 years ago, no consumer version of one has appeared. 3 years is an eternity in modern terms.

A running robot dog is still a very difficult problem that preoccupies grad students for years, with no-one having miniaturized one. The Boston Dynamics robots used rotational hydraulics so powerful, they could hop. Their 6 year old consumer sized robot was limited to very slow movement by the speed of the servos.

It became quite clear the spring aided Swiss robot can't turn or support the weight of a battery. If a legged running robot is required, the best alternative would use 2 fans blowing air to support most of the weight & stabilize it. The legs would just provide sideways balance & forward motion. It would have really short battery life. Running robot dogs are still firmly in the imagination.
