BEAR   战地搜寻和救助型机器人 美国: 美国 制造者: Vecna 年份: 2006

      BEAR是Vecna机器人技术的王牌计划。它的设计是为了发现、载送和营救受到伤害的人们，它可以做人类所不能做的事情：举起重物并长距离搬运。无论在战场上、在核反应堆的核心、在有毒的化学溢出物附近，还是在地震后结构危险的建筑物里面，BEAR都可以营救那些需要救助的人们。它的表现和人类相比丝毫都不逊色，甚至比人类更棒。这样就不需要有更多的人去冒生命危险。

      BEAR的技术专利悬而未决。该技术是三个要素的密切结合，它们是：受水力学控制的强有力的身体上部；以履带式的两条“腿”为特征的一个机动灵活的平台；动态平衡的行为（DBB）。DBB是机器人以“脚踝”为基础保持自身平衡的能力，这使它在充分伸展时能够站得笔直。事实上，无论依靠踝、膝、甚至是依靠臀部来保持平衡，BEAR都能保持挺直站立。

      BEAR现在正处于观念证明的发展阶段。BEAR的原型已经建立并配有一副强有力的躯干和两条胳膊，它的两只轮子上带有一个动态平衡系统。同时，BEAR的原型已经能够示范性地救起一个重量十足的假人，并且在怀抱假人保持力量平衡的情况下，可以挺直站立长达50分钟以上而不休息。这种履带式的活动系统目前正处于发展之中。

The BEAR robot is Vecna Robotics' flagship program. Designed to find, pick up and rescue people in harm's way, the humanoid BEAR robot can do what humans can't: Lift heavy loads and carry them long distances. Whether on a battlefield, in a nuclear reactor core, near a toxic chemical spill, or inside a structurally-compromised building after an earthquake, the BEAR can rescue those in need as well as or better than humans can, without risking additional human life.

The BEAR robot's patent-pending technology is a marriage of three elements: A powerful upper body controlled by hydraulics; an agile mobility platform that features two independent sets of tracked "legs"; and dynamic balancing behavior, or DBB. DBB is the capability of the robot to balance itself while on the balls of its "ankles", allowing it to stand upright while fully extended. In fact, the BEAR will be able to remain upright whether balancing on its ankles, its knees, or even its hips.

The BEAR is currently in proof-of-concept development stage. A prototype of the BEAR robot has been built and outfitted with a powerful torso and arms, together with a dynamic balancing system on two wheels. Together, the robot prototype has been able to demonstrate picking up a fully-weighted human dummy, and carrying the dummy around in its arms while dynamically balanced in an upright position for over 50 minutes without break. The tracked mobility system is currently in development.
