Just a quick note to announce that we have GM3 and GM9 motors back in stock, which means that Yellow Drum Machine Bundle and Let's Make Robots Start Here Kit are both available again.
New Sanyo Gear motors
Dave Hrynkiw
March 15, 2004
Wow! They're finally here! These are the original gear motors we used sooo many years ago to convert and power the Miniball kits (yes, they're under review for bringing back - don't rush us!).
We're the only place to find the whole assortment of four gear ratios - 75.7, 134.5, 196.6, and 297.1:1 reduction, and in all-metal gear-trains. These are truly beautiful little units, and being such quality, they're a bit more expensive than our regular gear motors. BUT, if you have a small-space, high-power requirement, nothing else will fulfill the job.
Ideal for applications needing light-weight actuators, like with antweight combat robots, or small (or quick!) walking robots!

Interesting Mini-sumo build
This mini-sumo design by Jeremy Bloyd-Peshkin features our wheels, and one of our favourite building materials, Sintra. We can't laser-cut sintra (PVC=bad stuff when burned), but milling it works well, as this builder shows. The asymmetric motor layout works, as proven by this contest-winning design (scroll to the bottom of the page).

It's snowing here. Here's the proof - a ruler measured with another ruler, reading about 7" depth of (what used to be) snow. It's a massive invasion of snowflakes, and they don't seem too friendly. The amount of snowfall we are experiencing now can prevent anyone in their right mind from being outside. And the […]
