重量比

• The joint designing has the requirements of small size , light weight , large output torque , wide motion area etc . the hydraulic drive mode , which has the character of great ratio between power and weight , huge load capacity , smart structure etc , can fulfill all the design demands
  针对机器人关节要满足体积小、重量轻、输出力矩大、运动范围大等设计要求，采用液压驱动的方式以其具有功率重量比大、驱动力大、结构紧凑等优点，可以充分满足机器人关节的设计要求。
