Description

Constrained trajectory planning method, equipment and storage medium for mobile operation robot
Technical Field
The invention relates to the field of mobile operation robot track planning, in particular to a constrained track planning method of a mobile operation robot based on a manifold approximate probability roadmap.
Background
Mobile manipulator robots often need to perform a series of constrained manipulation tasks safely and efficiently in complex scenarios, such as in chemical laboratories, between different instruments to complete a series of different chemical experiments, inside space stations, such as opening/rotating valves. These scenes are characterized by numerous and dense obstacles, which can make it difficult to find a collision-free trajectory that satisfies the constraints, but they are generally fixed and only subject to movement positioning errors or occasional placement of small objects. Existing constrained trajectory planning methods based on sampling generally include both reject sampling and constrained shaping. The sampling rejection method is simple to realize, but has low efficiency, and especially when the constraint conditions are strict, the sampling rejection is frequently generated, so that the planning time is greatly prolonged. While the constrained manifold approach improves sampling efficiency, collision detection is still required, which introduces a non-negligible time overhead in complex scenarios such as chemical laboratories. The existing track planning method is difficult to meet the requirement of obtaining a track with enough high quality while the planning time is as short as possible.
In view of this, the present invention has been made.

step 1, setting constraint and constructing an approximate graph of a constraint manifold;
Specifically, the step 1 includes the following steps:
Step 11, carrying out random uniform sampling in the whole potential form space A to obtain an initial potential form X 0, and then projecting the potential form X 0 onto the constraint manifold X by using a Newton-Raphson method to obtain a potential form X i;
Step 12, performing difference verification on each of the configuration x i and the configuration x j in the point set V obtained in step 11, as shown in fig. 3, a difference index is:
Wherein ε is a constant, set to 0.1; alpha is a constant and is set to 0.45; ρ is a constant, set to 1; By cutting space/> Log mapping at: /(I);/>Representation/>Is a transpose of (2); /(I)And/>The tangent space/>, respectively, of the constraint manifold at position x i And bit shape/>Space of department/>Is a group of radicals satisfying:
Wherein, Is the jacobian matrix of constraint function F at x; i is a k x k unit array;
If the bit shape x i meets the difference index, adding the bit shape x i into the point set V;
and 13, repeating the steps 11 and 12 until the positions in the point set V reach the specified number, and completing the construction of the point set V.
Step 14, for the position x k in the point set V, searching the nearest position x n in the point set V by using the euclidean distance;
Step 15, connecting the configuration x k in step 14 with the nearest neighbor shape x n by using a straight line, and equidistant sampling the straight line to obtain a plurality of configurations ,/>,/>And the following judgment is carried out:
Wherein, Is a small amount only when all sampling configurations/>All satisfy the above formula, the configuration/>And/>Connection between/>Effectively, adding the same into an edge set E;
Step 16, repeating step 14 and step 15 until the configuration is the same All the configurations in the set of points V or the specified number of connections have been tried. This is done for each of the configurations in V, resulting in an edge set E.
Preferably, in the step 1, the undirected graph constructed by using the point set V and the edge set EThe approximation of the constraint manifold X is shown in fig. 2. Where the set of points V is a set of vertices in the approximation graph, each vertex in the set corresponding to a potential shape that satisfies the constraint F. Edge set E is a collection of edges in the approximation graph, edges being possible paths for connecting different vertices, and spanning any edge does not leave the constraint manifold.
And 2, reconstructing the operation scene to obtain an operation scene model. Alternatively, the operational scene may be reconstructed using the SLAM method or NeRF method.
And step 3, executing an optimal trajectory planning algorithm PRM on the approximation graph obtained in the step 1 and the operation scene model obtained in the step 2 to obtain a roadmap containing the optimal trajectory.
In the step3, the PRM algorithm is two sampling modes, i.e. uniform random sampling and neighbor random sampling; wherein, for uniform random sampling, the number of bit shapes in the point set is as followsThus using uniform random sampling of an integerThe method realizes uniform random sampling, and the sampled configuration is the configuration at the ith index position in the approximate graph. For neighbor random sampling, two cases are classified according to whether the bit shape x belongs to the point set V:
(1) When (when) When, can sample the collection/>, of the bit shapesThe expression is as follows:
Wherein, Representing that there is an active connection to position form x and position form x n, V n is a collection of position forms x n connected to position form x and at a distance d or less;
(2) When (when) Or/>When the method is used, uniform random sampling is carried out in a sphere with a given shape x as a center and d as a radius, and the shape meeting the constraint is obtained by using the Newton-Raphson method as a sampling shape.

and 43, calculating the speed and the acceleration of the optimal track obtained in the step 42 according to the constraint of the mobile operation robot.
In the above step 4, the reason why the track planning is performed by using the LazyPRM method is that, in the operation scene of the mobile operation robot, the scene when the roadmap is generated by using the step 3 and the scene where the step 4 is located have a certain difference in consideration of factors such as artificial interference or mobile positioning errors of the robot, and since the connection between all the positions in the roadmap is considered to be collision-free by the classical PRM method in the query stage, the track obtained by directly using the method may collide with the scene, which is unacceptable. However, the delayed collision detection strategy of LazyPRM method can detect the collision after finding the track, and only plan the part of the track where the collision occurs again, so that the problems are avoided, the speed of track planning is increased, and the track obtained by each planning is ensured to be basically consistent.
And 5, the mobile operation robot executes the optimal track obtained in the step 4 to finish the operation process.
In summary, the constrained trajectory planning method of the embodiment of the invention can directly obtain the configuration meeting the constraint on the approximate graph by adopting the off-line construction and on-line sampling modes of the constrained manifold approximate graph, thereby reducing the calculated amount and realizing faster trajectory planning speed. Constructing a route map by utilizing an optimal track planning algorithm PRM, and carrying out online track planning by utilizing a LazyPRM algorithm, so that the quality of the track and the consistency of the track obtained by multiple planning are ensured. The method can enable the mobile operation robot to obtain a stable track with high enough quality in a short time, and improves the operation efficiency of the mobile operation robot.
