Further issues appeared after using the second iteration of leg lengths because the thickness of the legs, made of real material, interfered with the motion of the leg.
The Klann linkage is a mechanism that is used to simulate the foot steps I tried to program the motion of it in MATLAB but am currently stuck.

The Klann linkage is a six-bar mechanism that can be used in walking robots that simulate the gait of spiders or crab-like animals. It was patented by Joseph C. Klann in . Offset Slider-Crank Mechanism. Solves for two unknowns in a mechanical linkage system. 1 Rating examples (with published code) and movies of mechanical systems.
The feet slow down when they first contact the ground, as well as when they lift, which causes Klann to come to a stop with each step.
Klann Linkage with a Higher-Step. Leg Mechanism. The X Force was expected to be much less than the Y Force because the Y Force incorporates lifting the weight of the automaton and the X Force does not. Also, two legs are typically coupled together by a common actuator, which would constrain the set of possible gaits.

Also, when the ground height changes Klann's forward speed drops or reverses due to it's triangular-shaped foot-path. This means that modeling torque requirements is less straightforward: on one hand, the legs can't extend as far, so the actuators might have greater mechanical advantage
Moreover. 1) shows a Klann mechanism that creates a walking motion. system in part (a) ( c) Code in Matlab the system equations and try using the Matlab function fsolve.
MATLAB. I. INTRODUCTION.
Robotics & Electronics Klann Mechanism
A four-bar linkage, also called a four-bar, is the simplest movable closed The Klann linkage and the Jansen linkage are recent inventions that All Mathematical code is locatedin Appendix A for reference.
Sign up. If the robot were instead moved at the speed of the feet, then it would have a halting gait like that of the LEGO prototype further down.
For example, Klann's step-height can be increased by moving the lower rockers toward the center:. This leg mechanism is based off the Klann linkage leg mechanism. Servos can draw a lot of current, so this power supply needs to be pretty beefy.
