​New to linkages?  For some easier builds like Punchers, Jumpers and Biters check out Linkage Warm Ups.

​If you want to create a custom linkage for your walker like this simulation of Strandbeest's linkage optimized for LEGO, see Customize where you can find online optimizers for Jansen's, Klann's, TrotBot's and Strider's linkages.
​​
Strider's linkage plans can be found here.

​​TrotBot's linkage plans can be found here.

​Scott Anderson created his own 3D-printed, phone-controlled version of TrotBot - you can find his plans here.

​​UPDATE:  Here are some simplified instructions for building TrotBot's leg mechanism.  This leg works for all 6 legs of Hexapod TrotBot, and for all 8 legs of TrotBot Ver 3 and Mindstorms TrotBot Ver 3

​Trouble Shooting Tips:  A finished walker's legs should be easy to rotate by hand with the motors disengaged.  If you feel resistance, then look carefully at the legs to see if any are twisted due to leg parts connecting to other parts in the  wrong plane .  Also, make sure that all bushings have been added to the axles so that the legs and cranks don't collide.  Most importantly, be sure to use frictionless pins for joints designed to move.
