The two extremely springy tires in the Tamiya 70096 off-road tires set are about 50 mm in diameter and 30 mm wide. Use these if you want your robot to have a soft, air-cushioned ride across rough terrain. (Compatible with the Tamiya...

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...

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...

This ball caster kit includes a black ABS housing, a 1/2" diameter plastic 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 included...

This motor driver shield and its corresponding Arduino library make it easy to control two bidirectional, high-power, brushed DC motors with an Arduino or compatible board, such as the A-Star 32U4 Prime. The board features a pair of...

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

The Pololu 4-Channel RC Servo Multiplexer can be used with standard hobby radio control systems and servo controllers to allow easy switching of servo control between two independent sources using a separate auxiliary channel as the...

Enclosed battery holder for four AA cells. This holder features a lid that slides over the batteries and snaps into place to fully enclose them. It also features a switch that lets you open and close the electrical connection between the...

DRV8824/DRV8825 stepper motor driver carrier with dimensions Overview This product is a carrier board or breakout board for TI’s DRV8825 stepper motor driver; we therefore recommend careful reading of the DRV8825 datasheet (1MB pdf)...

Overview This product is a carrier board or breakout board for Allegro’s A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection; we therefore recommend careful reading of the A4988 datasheet (380k pdf) before using...

Zumo reflectance sensor array with labeled sensors and dimensions. The Zumo reflectance sensor array provides an easy way to add line sensing or edge detection to a Zumo robot . It features six separate reflectance sensors, each...

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...
