The invention discloses a four-footed walking
robot platform which is provided with a driving power via
cam rigidity by an internal-
combustion engine and is provided with a swerving power by a
servo motor system and the balanced stance of which is regulated. A compound
driving mode is established by finding a high efficient walking mode of combining the power technique of current car, tank and
tractor with the technique of modern computer and
robot technique based on the
research result of the current multi-footed
robot. 99% of driving power for the robot straightly walking on flat road is provided by the internal-
combustion engine. When rugged road appears or the robot needs to swerve, the
motor system regulates the balanced stance and finishes the swerving task. The robot of the invention not only can decrease the power of the
motor system, lighten the self-weight, lower the use frequency of the motor
system and prolong the service life of a screw rod, but also can completely imitate the four-footed animals, can realize continuous, smooth, stable, powerful and efficient walking and can continuously work for a long time in a complex environment.
