Variable-length bendable fully-flexible mechanical arm structure

The invention discloses a variable-length bendable fully-flexible mechanical arm structure. The structure is a fully-flexible mechanical arm device having a posture controlled by elastic rods, capable of telescoping, and having a tail-end position capable of achieving any point in 360 degrees. The flexible mechanical arm device is composed of the elastic rods, a base, springs, metal section sheets, binding belts and U-shaped buckles. The four elastic rods are driven through slide tables of servo motors, thus posture control for the flexible mechanical arm and position control for a free end at the top are realized. The structure is reliable in stability and complete in function, and the tail-end position is capable of achieving any position in an outer envelope surface. 本发明公开种可变长弯曲全柔性机械臂结构，该结构为种由弹性棒控制姿态，可以伸缩并且可末端位置达到360°上任意点的全柔性机械臂装置。本柔性机械臂装置由弹性棒，基座，弹簧，金属节片，扎带和U形扣组成。通过伺服电机滑台驱动四根弹性棒，从而实现该柔性机械臂的姿态控制与顶部自由端的位置控制。该结构稳定性可靠，功能完善，末端位置能够达到外包络面内的任意位置。
