A multi-joint bionic diploe with autonomous hydraulic distribution power comprises a connecting frame and
tail joints. A three-dimensional joint, a two-dimensional joint, a caudal spine device, a hydraulic power
system and an electronic control device are further arranged, the number of the
tail joints is larger than or equal to 4, and the three-dimensional joint is fixed to the connecting frame and connected with the
tail joints. The tail joints are connected end to end by the two-dimensional joint, the caudal spine device is connected with that tail joint through the two-dimensional joint,the hydraulic power
system is fixed in the cavity of the tail joint, and is respectively connected with the hydraulic interfaces of the three-dimensional joint, the two-dimensional joint and the caudal spine device through hydraulic pipelines. The
electric control device is fixed in the cavity of the connecting frame or / and the tail joint or / and the caudal spine device, and the electric controldevice is respectively electrically connected with the hydraulic power
system, the three-dimensional joint, the two-dimensional joint and the caudal spine. The invention has a simple structure and isconvenient to install and disassemble. The
advantage of low
failure rate, high reliability and high
bearing capacity make it convenient for bionic mechanical
scorpion to be used in earthquake rescue,security protection, military reconnaissance and field exploration.
