    • PROBLEM TO BE SOLVED: To provide an L-shaped retaining wall block capable of reducing construction and transportation costs and enhancing safety during the construction.SOLUTION: An L-shaped retaining wall body 1 is changed from a conventional concrete-made one into an FRP-made one, cutout parts such as a cutout part 3 are opened in a bottom, and a clearance between the bottom and a foundation part is filled with concrete by pouring the concrete from the cutout parts. Furthermore, because the bottom has a box-like shape with a concrete flow stop 5, concrete can be subsequently poured up to a thickness required as a foundation and this part becomes a concrete foundation, and an initial foundation can be simply formed. Meanwhile, construction and transportation costs can be reduced and safety during construction can be enhanced owing to weight reduction and facilitation of drilling and cutting-off processing as a result of using the FRP as a raw material.
    • 要解决的问题:提供一种能够在施工期间降低施工和运输成本并提高安全性的L形挡土墙块。解决方案:将L形挡土墙体1从传统的混凝土制品改为FRP 制成一个,诸如切口部分3的切口部分在底部打开,并且通过从切口部分浇注混凝土,在底部和基础部分之间的间隙中填充有混凝土。 此外,由于底部具有具有混凝土流动停止件5的箱状形状,因此可以随后将混凝土浇注到作为基础所需的厚度,并且该部分成为混凝土基础,并且可以简单地形成初始基础。 同时,由于使用FRP作为原料,由于重量减轻和钻井和切断加工的便利性,可以降低施工和运输成本,从而提高施工安全性。

    • PURPOSE: To efficiently control a wheel type omnidirectional vehicle(ODV) by describing its motion on a relative coordinate system fixed to the ODV itself. CONSTITUTION: Wheels for driving are connected through offset links, which can be respectively independently steered, to respective four apexes on the car body of an ODV 20. Since these offset links exist, even when the car body is set in a standstill state, respective wheels can be steered without cutting their ends. The relative coordinate system defined by an advancing velocity(v), turning radius ρ and angle ϕ formed by the lateral axis of the car body and the advancing direction is provided at the center of the car body and the motion of the ODV is designated corresponding to these relative parameters. The designated motion of the car body is converted to a timewise change (driving velocity) in displacement λ1 of wheels and a steering angle q1 of wheels by inverse dynamism and a correspondent control input is applied to the driving device of wheels. As a result, the acr body is turned with the turning radius ρ with a point oc as a center. Thus, control based on a control instruction with the car body itself as a reference is enabled. Besides, the driving velocity of the wheels and the measured result of the steering angle are converted to relative parameters by forward dynamism and the really performed action of the car body can be recognized.
