Haven't touched the dusted Mindstorm NXT at corner for long time I decide to combine it with lots of parts salvage from friends for 4 leg walker.

The leg idea and parts base on one of chassis from Lynxmotion:

DIsassemble the previous MANTIS:


Most parts are still from lynxmotion:


The rod is not long enough so I have to extens with that little piece of plate:


Put everything all together:


Servo controller at back


External battery @ bottom box

 


Basically 4 moves to make it moving straight and for turnning as well.

 

Lighter line means the leg up. Sorry for bad English but you get the idea.
