20080252247 | Quadruped Walking Robot - The present invention provides a quadruped walking robot the production costs and weight of which can be reduced by reducing the number of driving portions, and which is capable of carrying out stabilized walking motions even with the degree of freedom reduced in the leg portions. | 10-16-2008 |
20090200090 | Multiple-point grounding type foot portion supporting mechanism, biped walking robot equipped with the same, and control structrure therefor - The present invention provides a multiple-point grounding type foot portion supporting mechanism having excellent reliability, in which the respective supporting points passively follow unevenness of the grounding surface such as a road surface, and which is capable of quickly supporting foot bottoms at polygonal points and preventing falling over even on a grounding surface having level differences by fixing the supporting points when all supporting points are grounded. The multiple-point grounding type foot portion supporting mechanism includes: base portions each disposed on the foot bottom of the foot portion of a walking robot; three or more foot bottom supporting portions each having its one end part disposed and protruding downward from the bottom face of the base portion, each of which independently moves upward when being grounded and is slidably or rotatably supported; grounding sensors each disposed at the base portion or the foot bottom supporting portion, which detect grounding of the respective foot bottom supporting portions; and lock mechanisms disposed at the base portion, which control and brake the movements of all foot bottom supporting portions when the grounding sensors detect grounding of all foot bottom supporting portions. | 08-13-2009 |
20100009329 | MEDICAL TECHNIQUE EVALUATION SYSTEM, TECHNIQUE EVALUATION DEVICE, TECHNIQUE EVALUATION DEVICE PROGRAM - A tool for objectively evaluating the technique of a medical treatment such as an operation or a palpation performed by a doctor or a medical student. A medical technique evaluation system comprises a soft material member having an incision made in itself for simulative suture by a trainee such as a doctor or a medical student and elastic deformation by a force acting on the surroundings of the incision, reflective type photointerruptor for measuring the state values in three orthogonal axes according to the elastic deformation of the soft material member and a technique evaluation device for determining the evaluation score of the technique of the suture and ligation on the basis of the measured values from the reflective type photointerruptor. The technique evaluation device substitutes values based on the measured state values in the orthogonal three axes into a predetermined evaluation function to determine the evaluation score. | 01-14-2010 |
