Motor connections These wheels fit 2 mm diameter output shafts such as the ones on our sub-micro plastic planetary gearmotors. The tire is not removable. Due to small variances in the sub-micro plastic gearmotor’s output shaft, in some...

These tiny brushed DC gearmotors have a diameter of just 6 mm and weigh just over a gram, which makes them great actuators for miniature robots and very small mechanisms. They consist of a coreless motor fastened to a 26:1 or 136:1...

These tiny brushed DC gearmotors are available in a wide range of gear ratios—from 5:1 up to 1000:1—and with five different motors: high-power 6 V and 12 V motors with long-life carbon brushes (HPCB), and high-power (HP), medium power...

This rugged wheel is designed to fit securely on the output shafts of our micro and 15.5D metal gearmotors. These gearmotors should be mounted onto the side of the hub with the protruding teeth, as shown on the right. The output shaft...

These plastic mounting brackets allow you to easily and securely mount the ubiquitous 10 mm × 12 mm × 26 mm metal gearhead motors first popularized by Sanyo’s 12GN series (e.g. NA1S…NA3S), such as our micro metal gearmotors. We also...

Overview This ball caster kit includes a black ABS housing, a 1/2" diameter metal ball, two spacers (1/16" and 1/8" thick), and two #2 screw sets. The total height of the ball caster, 0.53", can be increased to about 0.7" using the...

Getting started with the Maestro Servo Controller Overview Maestro family of USB servo controllers: Mini 24, Mini 18, Mini 12, and Micro 6 The Mini Maestros are highly versatile (and compact) servo controllers and general-purpose I/O...

Add quadrature encoders to your micro metal gearmotors ( extended back shaft version required) with this kit that uses a magnetic disc and hall effect sensors to provide 12 counts per revolution of the motor shaft. The sensors operate...

Overview This board is a 3-channel time-of-flight proximity and distance sensor module based on the OPT3101 IC from Texas Instruments. Unlike conventional IR sensors that use the intensity of reflected light to estimate the distance to...

Overview This cable is designed to work with our Micro Metal Gearmotor Encoders with top-entry connector and with side-entry connector . It consists of six twisted 28 AWG color-coded wires that are terminated on both ends by female JST...

Overview The 3pi robot is designed to excel in line-following and maze-solving competitions. It has a small size (9.5 cm/3.7" diameter, 83 g/2.9 oz without batteries) and takes just four AAA cells (not included), while a unique power...

These tiny brushed DC gearmotors are intended for use at 6 V, though in general, these kinds of motors can run at voltages above and below this nominal voltage, so they should comfortably operate in the 3 – 9 V range (rotation can start...
