Let's Make Robots!

New LBD geared motor for small robots

DAGU have now released a modified version of our Little Black Duck analog servo.

This is the Little Black Duck servo, modified for continuous rotation with the control circuit removed making it into a simple geared motor with a ball raced output shaft. This motor is perfect for small robots and can be easily driven by an L293D or a controller with a built in "H" bridge such as our Micro Magician.

The video shows a simple robot using two of these motors to drive the wheels and a Little Black Duck servo to raise/lower the pen.

I will start playing with different wheels too.

I will get them in stock soon guys. Its on the list.

I am not sure who will sell them right now aside from our good friend CTC at Rocket Brand Studios.

can you provide a link to any suppliers?

What are we doing for available wheels, yo?

We have made a simple rubber tire that goes on a laser cut acrylic wheel that screws onto the round servo horn but there is a new "miniature" Wild Thumper all-terrain tire coming soon that I want to use with these motors as well.

say, what do you do with the servo boards once you take them out?

i have a couple i just soldered some pins on to that i keep as plug in modules for testing.

combined with a 555 circuit you can hook up sensors directly and turn an rc car in to
a beam bot.


We have had these specially made without control PCBs. This reduces the price a fair bit.

kewl :)

what are you selling them for?


I cannot tell you what we are selling them to the distributors for but they should be cheaper than the Little Black Duck servos. You Should see them in the online stores soon.
