Description
Technical field
The present invention relates to robotic technology field more particularly to a kind of legged type robot control systems based on bus steering engine
And its control method.
Background technique
In nature and human society, the place that can not be reached there are the mankind and the particular field that human life may be jeopardized
It closes, such as planetary surface building site, mine, Fire prevention and struggle against terror, these environment is constantly explored and studied, are sought
The feasible way solved the problems, such as is asked to become the needs of scientific technological advance and progress of human society.It is irregular and uneven
Landform is the common feature of these environment, is restricted the application of wheeled robot and caterpillar type robot.And sufficient formula machine
People is a kind of mode of discrete foothold, is adapted to landform complicated and changeable, and more limbs, multivariant design can be with
It is set to adjust body height according to job requirements " active ", to guarantee the stability of equilibrium of body.At the same time, when a limbs
Break down problem in operation, and legged type robot still can continue to operate, that is to say, that and it has one " fault-tolerance ",
An and characteristic at this moment wheeled, that caterpillar type robot is no.Therefore flexibility and environment of the legged type robot in movement
Wheeled, the caterpillar type robot of ratio possess significantly more advantage in adaptability.
Legged type robot is often used the joint executing agency that steering engine is used as at present.Steering engine is by shell, motor, reduction gearing
The servo-system that group, sensor, control circuit and interface cable form.Whether there are microprocessor and crystal oscillator by control circuit,
Steering engine can be divided into simulation steering engine and digital rudder controller again.Simulation steering engine and digital rudder controller are the impulse waves for receiving adjustable pulse width
Control the corner of steering engine, period 20ms, pulsewidth is 0.5ms~2.5ms, and pulsewidth is the middle position that 1.5ms corresponds to steering engine, be less than
The pulse steering engine of 1.5ms pulsewidth rotates forward, and the pulse steering engine greater than 1.5ms pulsewidth inverts.Traditional simulation is used in robot
