Mindstorm NXT 4 legs walker

Let's Make Robots Robots
1

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:

1280×848


Most parts are still from lynxmotion:
1280×848


The rod is not long enough so I have to extens with that little piece of plate:
1280×848


Put everything all together:
1280×848


Servo controller at back
1280×848


External battery @ bottom box
1280×848

 


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.

Nice robot. I also have an NXT lying in my closet (man I haven’t touched it for a year or so!) and I want to sell it to buy parts for custom robots.

Very cool robot.

I like how smooth the transition is when changing steps. The metal legs really match the colours of the NXT too.

I have one of the older NTX 2.0 (Older yellow ones) Do you know if they can be modified to run non-lego parts?

Personally I never try to build any custom sensor for NXT myself but I think they sell some customize tools out there.
