that's the power of dream.
To create a 2 legs robot that can run is a new milestone in robot industry, a technology break through.
Because running involves more complex calculation + faster machine response.The momentum, leg movement, hand swinging and the central of gravity change every mili-seconds, the robot must have the processor that fast enought to do the accurate calculation to archive good balancing, not to mention the mechanical leg and arm need to give fast response (adjustment) based on the result of accurate calculation.
