In order to realize a power assisting suit for assisting a nurse caring a patient is her arm, a hardness sensor of muscle using load cell and a pneumatic rotary actuator utilizing pressure cuffs have been developed. The power assisting suit consists of shoulders, arms waist and legs made of aluminum, and is fitted on the nurse body. The power assisting suit was originated with the concept of a master and slave system in one body. The arms, waist and legs have the pneumatic rotary actuators. The pneumatic rotary actuators construct with pressure cuffs sandwiched between thin plates. The action of the arms, waist and legs of the nurse were sensed with the muscle hardness sensor utilizing load cell with diaphragm mounted a sensing tip. The dent of the sensing tip corresponds to the hardness of the muscle so that exerting muscle force produces electric signal. This paper gives the design and characteristics of the power assisting suit using the cuff type pneumatic rotary actuators and the muscle hardness sensor verifying its practicability.

This study was to examine the optimum height of chair for standing up operation and to inspect the shake of the center of sole pressure and the characteristics of EMG during the standing movement. Standing movements performed at the height of seating posture (hip, knee and ankle joint were 90 degree), and at he height of ±2%, ±4% and ±6% of the seating posture. The center of sole pressure was measured by a force-plate and the EMG's of the muscles of lower limb were measured. The shake of the center of sole pressure was larger at higher sitting height, on the other hand, the EMG activity was larger at lower sitting height. The large shake of the center of sole pressure means the large transfer of center of Gravity, consequently the posture of standing up operation from high chair decreased the load of lower limbs.

様々な分野の知識を融合させてシステムの構築を行う組み込み技術者を育成する教育課程においては体験型実習科目や創成科目が非常に重要である。また、創成科目の効果を高めるためには、座学において実際の機器を用いた体験型演習を行い、創成科目と座学との連携を深める必要がある。体験型演習を実施するための多様な演習用機材を短期間に構築するための再構成可能な計測・制御システム教材の開発を行った。開発した教材は、無線LAN搭載小型Linuxボードと再構成可能な多目的I/O ボードから構成されており、同一のハードウェアで様々な科目に対応する教材を短期間に構築することを可能とした。
