Underwater walking robot, using Klann leg linkages in laser-cut and anodised aluminium. [1] The Klann linkage is a planar mechanism designed to simulate the gait of legged animal and function as a wheel replacement, a leg mechanism. The linkage consists of the frame, a crank, two grounded rockers, and two couplers all connected by pivot joints.
The leg component of an arachno-bot is its core. Each of the 8 legs is equipped with S.E.S joints that mimic a spider’s mechanics. A spider's leg joints are the mechanics that the arachno-bot's artificial legs mimic in the spider-inspired electrohydraulic soft-actuated joints (S.E.S for short).
In 1996, W-B. Shieh presented a design methodology for leg mechanisms. [4] The artwork of Theo Jansen, [5] see Jansen's linkage, has been particularly inspiring for the design of leg mechanisms, as well as the Klann patent, which is the basis for the leg mechanism of the Mondo Spider.

Necrobotics utilizes the spider's organic hydraulic system and their compact legs to create an efficient and simple gripper system. The necrobotic spider gripper is capable of lifting small and light objects, thereby serving as an alternative to complex and costly small mechanical grippers. [6]
In larger variants of arachnids, such as the tarantulas and hairy desert spiders, another mechanism used for locomotion is an elastic sclerite. [6] These sclerites are semi-rigid connectors between leg segments that allow storage and expending of potential energy.
Engineers figured out how to manipulate a dead, curled-up arachnid and transform it into a mechanical gripper. Scientists Are Using Dead Spider Legs as Gripping Claws. Thanks, We Hate It!
Jansen's linkage bears artistic as well as mechanical merit for its simulation of organic walking motion using a simple rotary input. [2] These leg mechanisms have applications in mobile robotics and in gait analysis. [3] [4] The central 'crank' link moves in circles as it is actuated by a rotary actuator such as an electric motor.
