Definitions
- the invention belongs to the technical field of humanoid robots, and specifically relates to a method for generating and optimizing the gait of a biped robot.
- the biped robot has the characteristics of human appearance. It adopts biped walking and two-handed operation. It is easy to adapt to the human working environment and use human tools. It has important applications in the aging society, family services, public safety and other dangerous environment operations, national defense and other fields. demand. Although biped robots have achieved landmark results in motion planning, balance control, operation, and system integration in a structured environment, compared with the wide application of industrial robots in industrial production, biped robots are far from practical applications. Big gap.
- the walking gait of the biped robot directly affects the walking performance of the robot. Different gaits have different characteristics such as stability, energy efficiency, and degree of anthropomorphism. Therefore, it is very important to design a reasonable walking gait. Humans have different walking gaits to adapt to different walking environments.
- an omnidirectional coupling of oscillating neuron units is proposed to generate foot and center of mass trajectories, and sensors are used to detect environmental information to form a feedback loop to obtain gait trajectories; in addition, there is a spherical hinge dual degree of freedom thumb root joint device that uses Dual motors are connected with threads, ball hinges and herringbone linkage mechanism, etc., which comprehensively realize the independent swing and fitting action of the root of the thumb; others have proposed a five-finger dexterous hand finger side swing and palm-pointing mechanism based on a screw linkage mechanism , Use the screw nut and connecting rod system to realize the movement of the finger base joint with two degrees of freedom.
- the placement position of the motor is restricted by the driven object, which occupies a large amount of palm space, increases the weight of the hand, reduces flexibility, and requires high precision in coordination with installation, and does not have the versatility of the driving method.
- a biped robot gait generation and optimization method is proposed, with the purpose of providing a biped robot gait generation method with higher universality.
- a biped robot gait generation and optimization method In the finite state machine, the biped robot's gait database is constructed according to the target pose of the biped robot's state; the conditions for switching between the states of the triggering robot are set; During each state switching process, the motion trajectory of the supporting leg is planned by the joint cubic interpolation method, and the motion trajectory of the swinging leg is optimized by the Gaussian pseudo-spectrum method; finally, the finite state machine generates a variety of different motion modes of the biped robot gait.
- the switching conditions include man-made triggers, time triggers, and event triggers.
- the time trigger is the duration between the set states
- the event trigger is whether the swing leg of the robot touches the ground.
- the state of the biped robot includes: the initial state of the robot standing on the ground with both feet, the state that only the right foot is supported, the state that the left foot touches the ground, the state that the left foot supports, the state that the right foot touches the ground, and the airborne state. status.
- the process of the joint cubic interpolation method is: according to the target angle ⁇ 1 , ⁇ 2 of the front and rear states, and the angular velocity of the front and rear states
- the duration between and the state is T, when the current state duration is t, the current reference angle ⁇ and angular velocity after cubic interpolation for:
- the method for optimizing the motion trajectory of the swinging leg by the Gaussian pseudospectral method is:
- M is the inertia matrix of the joint space
- C is the resultant force vector of Coriolis force, centrifugal force and gravity
- q sw is the angle between the hip joint and the knee joint of the swing leg
- Is the angular velocity of the hip joint and the knee joint of the swing leg
- ⁇ sw is the driving torque
- S3 establish an evaluation function: Among them, x e is the state at the last moment, and S, Q, and R are weight matrices;
- x(T) is the real state time history
- X(T) is the state time history approximated by the Lagrangian interpolation polynomial
- t 0 is the start time
- t f is the end time
- X 0 is the state time history at t 0
- X f is the state time history at t f
- w k is the Gaussian integral weight
- g is The piecewise integral function is the integral of the dynamic equation
- T k is the Gauss point
- X k X(T k )
- k 0,1,...,N;
- the position of the end of the foot of the swinging leg is restricted, and the position of the end of the foot of the swinging leg in the vertical direction should be greater than 0;
- the present invention provides a method for generating and optimizing the gait of a biped robot, which does not simplify the biped robot to avoid errors caused by the inaccuracy of the model, thereby increasing the difficulty of control; using the finiteness and symmetry of the finite state machine to plan dual
- the operation of the foot robot simplifies the planning process, and adopts the whole-body dynamics constraint to reduce the energy loss during the operation of the biped robot; because there is no ZMP restriction, this method can be used on either a footbed or a point-footed biped robot. Applicability improves the universality of the method.
- Figure 1 is a flow chart of the method for generating and optimizing the gait of the biped robot of the present invention
- Figure 2 is a schematic diagram of different states of the biped robot during walking
- Figure 3 is a schematic diagram of the motion state of the biped robot in different modes.
- FIG. 1 A biped robot gait generation and optimization method is shown in Figure 1:
- the biped robot divides the robot states into 6 types according to the different supporting legs during walking. They are the initial state of the robot standing on the ground with both feet, the state where only the right foot is supported, and the left foot touching The state of the ground 2, the state of the left foot support 3, the state of the right foot touching the ground 4, and the empty state, the joint target angle and walking reference speed are set through the human walking state information; in the finite state machine, according to the different states of the biped robot Construct the gait library of the biped robot with the target pose.
- the switching conditions include human trigger, time trigger and event trigger.
- the event trigger is specifically whether the robot’s swing leg touches the ground; as shown in Figure 2, when a human input control command After that, the robot starts to move from the initial state, that is, using human touch; after a period of time, it reaches state 1, and the robot starts to enter the cycle of walking cycle.
- the cycle walking phase there are 2 switching conditions for switching between the 4 states.
- time triggering that is, setting whether the current state continues to run for 0.2s
- event triggering that is, the robot swings its legs.
- the switching rule is: when state 1 is switched to state 2, and state 3 is switched to state 4, the condition is whether the current state continues to run for 0.2s, when state 2 is switched to state 3, and state 4 is switched to state 1.
- the condition is whether the swinging leg of the robot touches the ground; Figure 2 shows that the gait of the robot is symmetrically distributed, which is consistent with the rhythmic periodic motion of human walking. If the robot is in the airborne state during walking, when the robot is in the airborne state, the robot will keep the posture of the whole body unchanged and wait for the robot to land. When it detects that both feet touch the ground, it will switch to state 1.
- each state in the gait library only represents the pose at the initial moment of the current state of the robot, when switching between the two states, the reference joint trajectory will jump, causing the robot to run free when executing the planned trajectory. Stable phenomenon), so it is necessary to obtain a smooth trajectory through an interpolation function between the two state target angles. Because the angle of the supporting leg changes little and plays a supporting role, only the cubic interpolation function is used for simple trajectory planning; for the swing leg due to the large motion range, it plays an important role in the balance and stability of the robot, so Gaussian pseudo-spectrum is used Method of optimization method for interpolation planning. Finally, the finite state machine generates the gait of the biped robot with multiple different motion modes. The specific process is as follows:
- the target angle and angular velocity of the two states are ⁇ 1 , ⁇ 2 and The duration between states is T, when the current state duration is t, the current reference angle ⁇ and angular velocity after three interpolations for:
- a 0 ,a 1 ,a 2 ,a 3 ,s are only process variables in the calculation, and have no practical meaning;
- M ⁇ R 2 ⁇ 2 is the inertia matrix of the joint space
- C ⁇ R 2 ⁇ 1 is the resultant force vector of Coriolis force, centrifugal force and gravity, They are the angle of the hip and knee joints of the swinging leg, the angular velocity of the hip and knee joints of the swinging leg, and the driving torque of the hip and knee joints of the swinging leg.
- Is the angle of the hip joint of the swing leg Is the angle of the knee joint of the swing leg, Is the angular velocity of the hip joint of the swing leg, Is the angular velocity of the knee joint of the swing leg, Is the driving torque of the hip joint of the swing leg, It is the driving torque of the knee joint of the swing leg.
- the dynamic equation of the swing leg must be deformed to meet the requirements of the optimization algorithm. Establish a nonlinear state equation:
- the angular acceleration can be expressed as:
- x e is the state at the last moment
- S, Q, and R are the weight matrices
- t is the time.
- t 0 is the start time
- t f is the end time
- x(T) is the real state time history
- X(T) is the state time history approximated by Lagrange interpolation polynomial
- w k is the Gaussian integral weight.
- the position of the end of the foot of the swinging leg needs to be restricted, that is, the position of the end of the foot of the swinging leg in the vertical direction should be greater than 0 .
- the Gaussian pseudospectral method needs to meet the set whole-body dynamics constraint conditions to optimize the motion trajectory of the swinging leg.
- the method to construct the robot's whole-body dynamics equation is:
- D, N, G, B, J are the matrices related to inertia, Coriolis force, gravity, moment transformation and Jacobian respectively
- F E is the external force on the end of the swinging leg
- the simulation experiment proves that the method can generate the gait of the biped robot with many different motion modes from the finite state machine. As shown in Figure 3, a variety of different modes of movement can be formed, including slow walking, fast walking, jumping forward and so on.
- the present invention uses the state machine to generate the motion mode of different robots, which simplifies the planning process and
