Unique Multi-link Leg Design Enables True Robot Running (Video)

One of the most active debates about robots running ability has always centered around whether or not both of the robots feet leave the ground at the same time. When Honda's ASIMO humanoid robot was first demonstrated running, lots of critics immediately questioned if it had actually achieved "running" to that point or not. Eventually videos surfaced showing that indeed, for a fraction of a second, both of ASIMO's feet were in the air.

That being said, ASIMO is a multi million dollar, multi-decade research project backed with a staff of engineers and developers from one of the world's most well known automobile manufacturers. Could the same performance, at least as far as running is concerned, be achieved by a hobbyist working essentially alone in his workshop?

Apparently so...

The FrostyDesign robot uses a unique multi-link leg design that enables it to achieve full speed running with both feet leaving the ground without falling or tipping, and it can stop on a dime. Even more impressively, it accomplishes all of this without using gyro sensor feedback.

The FrostyDesign video playlist below includes a 300 fps clip showing how the robots feet actually leave the ground, a clip with the robot running full out, another clip demonstrating the robots ability to stop quickly without losing its balance, plus two clips showing the multi-link leg design in detail.

  1. Why do so many biped robots have no toes? It seems to me that nature provided us with toes so we could run faster and be more agile. I don’t see any advantage of not using toes.

    It is not that it is not possible because I have seen video’s of toes-equipped bipeds that can walk pretty well.

  2. Toes are small, and are very hard to write code for unless you are heavily funded or have a foot fetish.

    Roboticists have a hard enough time creating walk/run/stop algorithms for their robot feet.

    Adding toes would only complicate every process.

    Not only then would you be working with a couple servos for the leg/ankle you would then exponentially raise the difficulty of even a walk animation when you add a couple toes.

    Unless heavily funded, toes are a luxury most robots can’t afford unless absolutely necessary.
