This ball caster can be used as a replacement 3pi robot part or as a general-purpose ball caster. When mounted through a hole in a chassis that uses our micro metal gearmotors and our 32×7mm wheels , as on the 3pi, this ball caster is...

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...

This brushed DC gearmotor is very compact and weighs only 0.7 ounces (19.5 grams) — perfect for building a quick, miniature robot. The recommended operating voltage range for this motor is 3 to 6 V, though the gearmotor can start...

This #2-56, pan-head screw is 1" long. It is made from steel, is zinc-plated, and comes in packs of 25. Dimensions · Length: 1.00 in General Specifications · Threaded type: 2-56

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)...

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...

Overview This 5 V boost (step-up) voltage regulator generates higher output voltages from input voltages as low as 0.5 V, and it also automatically switches to a linear down-regulation mode when the input voltage exceeds the output. This...

Tamiya’s steel-ball caster is a good way to give a “third wheel” to a small robot powered by a differential drive. The kit comes with enough parts to make two casters, either 25 mm or 35 mm in height. The Tamiya 70144 ball caster from...

This gearmotor consists of a low-power, 6 V brushed DC motor combined with a 171.79:1 metal spur gearbox, and it has an integrated 48 CPR quadrature encoder on the motor shaft, which provides 8245.92 counts per revolution of the...

This 120:1 gearmotor (gearbox with brushed DC motor) is very compact and weighs only 0.7 ounces (20 grams) — perfect for building a quick, miniature robot. This gearmotor starts rotation at 0.58 V, drawing only 46.5 mA at 7 RPM. At 5 V,...

Overview The Tamiya 4-speed crank-axle gearbox has four possible gear ratios, including the highest gear ratio of Tamiya’s gearbox series, 5402:1, as well as 126:1, 441:1, and 1543:1. This gearbox also features a worm gear, which locks...
