Modular Robot Climbers
The goal of modular robots is to achieve versatility in the field, while satisfying any number of traditional robot tasks. We chose the task of traversing terrain by climbing, and present various methods of climbing with modular robots. In particular, we focus on the tasks of climbing across a horizontal rope, climbing up a vertical rope, and climbing up stairs using the Superbot modular robot....
متن کاملFingertip injuries in rock climbers.
The sport of rock climbing has undergone a significant change in recent times with technically harder climbs being attempted more often. This has meant that climbers have taken to more training including weight training, using artificial climbing walls and the more traditional 'bouldering' i.e. training on natural outcrops and boulders. This increase in standards has led to injuries associated ...
متن کاملA Society of Hill-climbers
|This paper is concerned with function optimization in binary search spaces. It focuses on how hill-climbers can work together and/or use their past trials in order to speed up the search. A hill-climber is viewed as a set of mutations. The challenge is twofold: one must determine how many bits should be mutated, and which bits should preferably be mutated, or in other words, which climbing dir...
متن کاملLumbrical tears in rock climbers.
Performance rock climbing places high demands on the hand and may lead to specific injuries. In a "one-finger-pocket" hold, the interphalangeal joints remain in 20-40 degrees flexion. To increase the maximum force of the holding finger by the quadriga effect, the interphalangeal joints of the adjacent fingers become almost maximally flexed. Holding a "one-finger-pocket" with the ring or small f...
متن کاملHand injuries in competition climbers.
All 67 of the competitors at the first British Open climbing competition were examined for signs of previous or present hand injury. The most important clinical findings were that 26 per cent of the climbers had signs of previous injury to the A2 pulley of the ring finger, and that fixed flexion deformity of the proximal interphalangeal joints of the fingers was present in 24 per cent.
