摘要： A walking assistance device (1) has a receiving portion (2) which receives a part of the weight of a user (A) applied from above and a pair of left and right leg links (3R, 3L) connected to the receiving portion (2) through first joints (10R, 10L), with foot attachment portions (15R, 15L) at lower ends of the leg links (3R, 3L) attached to the feet of the legs of the user (A), respectively. The leg links (3R, 3L) are connected to the receiving portion (2) in such a way that, when each leg of the user (A) is a standing leg, a line of action of a supporting force transmitted from a third joint (14R, 14L) of the leg link (3R, 3L) to a crus frame (13R, 13L) out of the supporting force acting on the leg link (3R, 3L) from the floor side passes through a specific point (P) located upper than the receiving portion (2) within an anteroposterior width of a contact surface between the receiving portion (2) and the user (A) from the third joint (14R, 14L), viewed in the sagittal plane. Thereby, it is possible to stably apply a desired lifting force for reducing the weight to be borne by the user with his/her legs to the user.

摘要： The joint rotational angles of joints 9, 11 and 13 of each leg 2 of a bipedal walking body 1 are detected to grasp the positions/postures of the corresponding rigid bodies 10, 12 and 14 of each leg 2 on a leg plane passing the joints 9, 11 and 13 of each leg 2. At the same time, the acceleration of a reference point (the origin of a body coordinate system BC) of the bipedal walking body 1, the floor reaction force acting on each leg 2 and the position of an acting point thereof are grasped in terms of three-dimensional amounts. Two-dimensional amounts obtained by projecting the acceleration, the floor reaction force and the position of the acting point thereof, and the positions/postures of the corresponding rigid bodies of each 2 onto the leg plane are used to estimate the moments acting on joints of each leg on the basis of an inverse dynamic model. The stability of the estimated values of joint moments can be improved while securing the accuracy of estimating the joint moments in the bending and stretching directions of each leg, considering three-dimensional motions of the bipedal walking body.

摘要： A walk assistance device capable of transmitting a force generated by a leg link to a user's trunk via a load transfer portion, wherein the leg link includes an upper first link portion connected to the load transfer portion via a first joint portion, a lower second link portion connected to a foot attachment portion via a second joint portion, a middle third joint portion connecting the first link portion to the second link portion such that a distance between the first joint portion and the second joint portion is variable, and a driving source that drives the third joint portion. The moment of inertia around the first joint portion of the leg link is reduced to decrease a load on the user's leg in walking. The driving source is disposed above the third joint portion of the first link portion so that the center-of-gravity of the entire leg link is located above the third joint portion. In the case where the driving source includes an electric motor and a reduction gear, the electric motor is disposed above the reduction gear.

摘要： A control device and a control program for a walking assist apparatus set a desired lifting force to act on a user from a seat and distribute the desired lifting force to each leg link of the walking assist apparatus according to the ratios of treading forces of the legs of the user measured on the basis of outputs of force sensors so as to determine the share for each leg link. Then, an actuator of each leg link is controlled to generate a force for the determined share. Thus, a force required for the user to support himself/herself with his/her leg or legs on a floor can be reduced while using a reduced number of parts to be attached to each leg of the user. Moreover, an assist force for achieving such a reduced required force can be properly shared between the leg links associated with the legs of the user.

摘要： A method is presented for determination of single stance or double stance state of leg bodies of a bipedal mobile body (BMB). In a single stance state, a floor reaction force acting on a leg body touching the ground is estimated based on an equation of motion for the center of gravity (GO) of a BMB. In a double stance state, floor reaction forces, Fr and Ff respectively, acting on the leg bodies are estimated based on an equation of motion for GO of a BMB and an expression of relation between components of Fr and Ff on the respective leg bodies and positions of ankle portions of the leg bodies relative to the GO of the BMB. Further, based on an inverse dynamics model, knee and hip joint moments of each leg body are estimated using floor reaction force values.
