英国霍尔大学的研究人员发明了一种制造机器人手臂的方法。这种手臂是通过高聚物的扩张和收缩移动,而不是通过传统的液压、电子或气动刺激移动的。该研究小组声称,这种高聚物肌体比用现行技术驱动的肌体要灵活得多,因为只要加某种化学试剂,它们就能变硬或变软。许多生物体将化学能转变成机械能,从而产生运动,但机器却很少能这样。泰勒等人说他们通过肌体 Researchers at Hall of Science in the UK invented a method of making a robot arm. The arm is moved by the expansion and contraction of the polymer, rather than by traditional hydraulic, electronic or pneumatic stimuli. The team claims the polymer body is much more flexible than current-powered bodies because they can harden or soften with a chemical. Many organisms convert chemical energy into mechanical energy, resulting in exercise, but machines rarely do. Taylor et al say they pass the body
