Definitions
- the present invention relates generally to a device for controlling a robotic system for assisting the mobility of a user, and in particular for assisting the mobility of the upper limbs of a user. It also relates to a method for controlling a robotic mobility assistance system using the device.
- various devices are known for controlling a robotic system for assisting the mobility of a user, in particular for the upper limbs.
- a keyboard / mouse / stick control system which has the defect of constraining the remaining functional capacities or those of the valid member of the user, a myoelectric control (by electromyograms), a control by measurement of the 'brain activity (for example with a measurement of
- EEG electroencephalograms
- a first major drawback of these devices is that they impose an artificial law of control on the user. This requires a significant learning time, up to several weeks for myoelectric control and / or control based on brain activity, and the difficulty of control increases rapidly with the number of joints to be controlled.
- most of these devices are based on joint space control, that is, each joint is controlled individually and often sequentially, one after the other. The cognitive load to perform a gesture is then important because the user has to break down the movement into sub-movements of each joint, which nobody usually does.
- the present invention aims to remedy these drawbacks.
- the subject of the invention is thus a device for controlling a robotic system for assisting the mobility of a user, said robotic system comprising at least one active element for assisting mobility capable of assisting an action. of the user's given mobility.
- the device comprises a detection system capable of detecting a compensatory movement of the user associated with said mobility action, said compensatory movement being a movement made by an invalid user, or valid but locally and / or temporarily constrained, to perform at least part of the mobility action, and which replaces at least part of the normal movement that a valid unconstrained user would perform to perform this mobility action, and a control system capable of controlling said at least one active element when said compensatory movement is detected.
- a compensatory movement, or compensatory movement can be defined as a movement carried out by an invalid user (with a disability reducing part of his mobility) or valid but locally and / or temporarily constrained, to perform at less part of the mobility action, and which at least partially replaces the normal movement that a valid, unconstrained user would perform to perform this mobility action.
- the invalid user thus uses the parts valid parts of his body to compensate for invalid, missing, deficient or constrained parts, and for example at least to engage the mobility faction.
- the idea of the invention stems from the observation that, when a user is assisted by a robotic system for assistance in mobility, if said robotic system is not in the desired geometric configuration to achieve a task and if said user has no direct means to change said configuration, said user will naturally tend to generate a compensatory movement, as if the robotic system were "invalid". This observation also applies, sometimes, when the direct means of control exist but represent too great a cognitive or physical cost.
- the mobility action is associated with a predetermined compensatory movement, and an element is controlled. active mobility assistance as soon as the compensatory movement is detected.
- the control of the active element is not carried out directly according to the mobility action, but from the detection of a compensating movement associated with the mobility action.
- the device according to the invention thus uses the body's natural reaction to a
- the control of the active element is all the more natural as it takes place in the space of the mobility action (space of the task), and not in the joint space.
- the invention also makes it possible to reduce the compensation movements
- compensatory proximal joints eg, mobilized to compensate for the absence of an amputated limb
- the active element may be an element for assisting the mobility of an upper limb of the user.
- the active element can be a robotic arm prosthesis or a
- the mobility action can thus be to reach a target, for example using the arm, and the compensatory movement can be an inclination of the user's torso.
- the active element can also be an element for assisting the mobility of a lower limb of the user.
- the detection system may be able to detect a difference between a position of
- the reference position can be defined generally as being a
- said at least one active mobility assistance element may be an active element intended to be secured to the user.
- Said at least one active mobility assistance element can thus be a
- motorized joint intended for example to control a faulty or absent joint from the user or an additional / supernumerary robotic joint.
- the active element can thus be a robotic arm prosthesis (for example a prosthetic elbow joint), for a user with an amputated upper limb, or even an assisting arm exoskeleton, for a user with paralysis of the legs extremities or muscle weakness, in a home environment.
- a robotic arm prosthesis for example a prosthetic elbow joint
- an assisting arm exoskeleton for a user with paralysis of the legs extremities or muscle weakness, in a home environment.
- said at least one active mobility assistance element may be an active element external to the user.
- Said at least one active element of mobility assistance may in this case be an active element for controlling a movement of a target of the user, for example an active element for controlling a movement of the user. 'an object that the user wishes to reach or an object on or with which he is working.
- control system may also be able to induce a correction of the
- the subject of the invention is also a set of assistance for the mobility of a user.
- the assembly according to the invention comprises a device described above and a robotic system controlled by said device.
- the subject of the invention is also a method for controlling a robotic system for assisting the mobility of a user.
- the method according to the invention uses a device described above.
- the method can comprise the steps of:
- FIG. 1 is a diagram in the form of a block diagram illustrating the overall operation of a control device of a robotic mobility assistance system according to the invention
- FIG. 5 is a graph illustrating the evolution over time of the angle of inclination of the trunk and the flexion angle of the elbow of the user of Figures 2 to 4, in accordance with a first embodiment
- FIG. 6 is a graph illustrating the evolution over time of the flexion angle of the trunk and the flexion angle of the elbow of the user of Figures 2 to 4, in accordance with a second embodiment
- FIG. 7 is a graph illustrating different simulations of the evolution over time of the flexion angle of the trunk and the flexion angle of the elbow in a user performing a pointing gesture and in different cases: natural gesture , gesture with blocked elbow (resulting in significant compensation of the trunk) and gesture with the proposed command (here automatically controlling the movement of the elbow as a function of the trunk compensations).
- the device according to the invention makes it possible to control a robotic system
- mobility assistance and in particular mobility assistance of the upper limbs, for example an upper limb prosthesis or exoskeleton. It uses as a command input the compensatory movements naturally implemented by the central nervous system (CNS) to perform functional tasks, for example, in the example which will be described, when the mobility of the upper limb (s) of the user is reduced.
- CNS central nervous system
- 0c denotes the current position of the body and b ’denotes the matrix of angular velocities of robotic joints.
- the invention uses a control algorithm which helps to aid the mobility of an upper limb.
- the algorithm allows intuitive control of the device because it relies on the use of strategies naturally implemented by the central nervous system to overcome a reduction in this mobility.
- the device according to the invention was tested on ten healthy users whose elbow movement was driven by a robotic joint, of the exoskeleton type. The users wore sensors on the trunk and on the arm. The experiment consisted of hitting a set of six targets, located at different distances and at different heights. All users have passed the mobility action, correctly controlling the articulation through the implementation of strategies
- a user 1 is initially in a reference position, the trunk being arranged vertically.
- the reference position can be generally defined as being a comfortable position, without postural compensation, which the user would naturally adopt to carry out the mobility action if he had control of all his joints.
- the reference position of the trunk is a leaning position, because certain gestures require the user to be naturally leaned.
- the mobility action consisting in reaching a target distant from the user
- the user whose arm is disabled will naturally tilt the trunk 5 forward to compensate for the disability of his arm.
- the associated compensatory movement is the tilt of the trunk 5 forward.
- sensors determine the inclination of the trunk 5 relative to the reference position of Figure 2.
- sensors arranged on the trunk 5 user such as deformable elastic sensors, or optical sensors.
- the compensatory movement is detected and the device 2 will control the active element of mobility assistance which is in this example a prosthetic elbow joint 3.
- the device 2 controls the opening of the prosthetic elbow which will allow the user 1 to reach the target 4 (FIG. 4).
- a two-dimensional inverse kinematic model is used for the elbow joint.
- a three-dimensional model can be considered more generally, with for example at least two motorized joints.
- the invention is distinguished by its natural control law, which only uses the strategies already implemented naturally by the central nervous system, and therefore requires very little learning. The user does not have to think about what to do. In addition, the order is carried out in the space of the mobility action (space of the task). What matters is not to move a joint, but to perform a given gesture, to position the hand in a given place.
- the exit from the law of command is not the movement of a single joint, but the coordinated movement of all the controlled joints necessary to perform the desired gesture, combined with the joints that the user always controls naturally
- no non-amputated person reflects on the individual position of their joints. The person is focused on the object to be reached, and therefore on the position of their hand, and they control their arm in the space of the task.
- the invention therefore reduces the learning time and the cognitive load. Its implementation is quick and easy, as there is no training phase for the algorithm.
- the small number as well as the small size of the motion sensors allow a use without constraint, in an open and domestic environment.
- FIG. 5 illustrates the evolution over time of the angle of inclination of the trunk Qt and of the flexion angle of the elbow b of the user when the mobility action is the seizure of a object.
- the user's trunk is in its reference position Qo.
- the user eager to reach the target object with his hand, will initiate a compensatory movement which is the tilting of the trunk forward.
- the device's control system controls the opening of the prosthetic elbow joint.
- the elbow thus opens gradually, from a bending angle bo to a bending angle bi, which brings the hand closer to the object to be grasped.
- FIG. 6 illustrates the evolution over time of the angle of inclination of the trunk Qt and of the angle of flexion of the elbow b of the user when the mobility action is the grasp of two objects .
- the entry of the first object begins in the same way as in the mode of
- FIG. 5 From a reference position Qo of the trunk of the user, the latter engages a first compensatory movement of the trunk forwards until the trunk is inclined to a predetermined value Qi, characteristic detection of the first compensatory movement.
- the device control system controls the opening of the prosthetic elbow joint from a bending angle bo to a bending angle bi, which causes the hand to move closer to the first object to be grasped.
- the user then wishes to enter a second object, which is closer to him than the first object.
- the user will then initiate a second compensatory movement, which is to tilt the trunk backwards so that their hand is closer to the second object.
- the device's control system commands the closure of the prosthetic elbow joint. The elbow thus closes gradually, from the bending angle bi to a bending angle b2 allowing it to reach the second object.
- FIG. 7 illustrates various simulations of the evolution over time of the angle of inclination of the trunk and of the angle of flexion of the elbow, the mobility action being to reach a target in the space.
- Three configurations have been considered: a user whose elbow joint is valid (“natural” curves), a user whose elbow joint is not valid, without the assistance of the device (“blocked elbow” curves) , and a user whose elbow joint is not valid with the assistance of the device (“compensation detection” curves).
- the control system of the device according to the invention can also be seen as a simple approach to correcting the compensatory movement.
- an active robotic element is in fact controlled so as to decrease the inclination of the torso when the compensatory movement has been detected: the elbow opening is actually increased so as to compensate for the decrease in torso tilt.
- the device can not control the user to move closer to the object to be reached, as has just been described, by bringing the hand closer to the object by opening or closing the elbow, but ordering the object to be reached to be brought closer to the user.
- a robotic active element integral with the object is controlled so as to bring the object closer to the user's hand when the compensatory movement is detected.
- This embodiment can of course be combined with the embodiment in which the user is ordered to move closer to the object to be reached.
