How cool! With these new Lego NXT compatible Linear Actuators you can easily add strong linear motion to your next Lego Mindstorms project. We now offer both 50mm and 100mm varieties.

Time to expand your building power with your Lego Mindstorms®. You must be tired of rotating things all day with regular old motors. It’s time to start moving things bach and forth, up and down, in and out! Like a REAL engineer. Firgelli actuators will make you the coolest kid on the block for certain.

Lego Mindstorm®, Power Functions®, and Technic® compatible Linear Actuators. These linear actuators are self contained units which include an electric motor. They will push up to 25N and move at 12mm/s unloaded.

For use with your NXT® Brick you will need a standard NXT® connection cable to connect it in place of one of the Mindstorm® Servos, and you will need to download the Firgelli L12-NXT Block here.

For manual use with Lego Power Functions® you will require the Cable-NXT-PF available on this site. For manual use with older Lego Technic® style battery packs you will require the Cable-NXT-Technic available on this site.
