This miniature, high-torque gearmotor has a 1000:1 gearbox, making it a great choice for applications requiring fine control at very low speeds. These units have a 0.365"-long, 3 mm-diameter D-shaped output shaft.Note: Because of the high gear ratio, these motors can generate enough torque to damage themselves, so you should avoid stalling them. Also note: this gearbox is longer than that of most 12mm micro gearmotors, so our micro metal gearmotor brackets will not fit this motor....

This gearmotor consists of a high-power, 6 V brushed DC motor combined with a 46.85:1 metal spur gearbox. The gearmotor is cylindrical, with a diameter just under 25 mm, and the D-shaped output shaft is 4 mm in diameter and extends 12.5 mm from the face plate of the gearbox.Key specs at 6 V: 200 RPM and 550 mA (max) free-run, 115 oz-in (8.5 kg-cm) and 6.5 A stall.Note: Stalling or overloading gearmotors can greatly decrease their lifetimes and even result in immediate damage. For these...

This gearmotor is a miniature (0.94" x 0.39" x 0.47"), high-quality, high-power motor with 30:1 metal gearbox, similar to Sanyo's popular 12 mm gearmotors.

Once the...

These miniature tank tracks are great for small, indoor, tracked robots. Each track link is injection-molded from ABS, and the links are held together by 1/16in. stainless steel dowel pins. The track is 0.9in. wide, and the pins are spaced approximately 0.54in. apart. These tank tracks are smooth for operation on one of the most common types of terrain that your robot might encounter: carpet!One pack contains ten loose links and pins.0-PL415

This programmer is a compact solution for programming the 3pi robot through a USB port. The programmer incorporates a USB-to-serial adapter and emulates an AVR ISP programmer so that you can program your 3pi with any software that can talk through a serial port to an AVR ISP, such as Atmel’s AVR Studio and AVRDUDE, which is included in the open-source WinAVR package. The unit also doubles as a USB-to-serial adapter (TX and RX only), allowing you to communicate with your 3pi, or any other...

This multi-color LED contains red, green, and blue elements that can be mixed to produce any color. Unlike many other RGB LEDs, this unit has a diffused white lens that blends the colors without any additional diffusers or reflectors. This LED is sold individually.Size: 5mmCurrent Rating: 30mAColor: RGBLens Type: White diffusedPlease see the data sheet and detailed drawing for more information, located in the "Other Documantation" and "Alternate Pictures" tabs. 0-PL1074 Data Sheet ...

The ShiftBrite is a module by macetech that integrates the Allegro A6281 3-channel constant current LED driver with a large, high-brightness RGB LED. Using just three digital output pins and a simple protocol, your microcontroller can control a long chain of ShiftBrites. Each ShiftBrite in the chain can be independently changed to any of the 1,073,741,824 possible colors to create dynamic displays and decorations. Adjustable current for each color channel lets you correct for slight...

The Orangutan robot controller is a complete control solution for small robots. It includes an 8-character x 2-line liquid crystal display, two bi-directional motor ports, a buzzer, three pushbuttons, and up to 12 user I/O lines, yet the compact module measures only 2.00" x 1.85" and weighs less than 1 ounce. Because of the complete feature set, very few additional components (such as sensors or motors) need to be added to complete the electronic portion of a small robot. The small package...

The Pololu serial 16-servo controller allows you to control up to sixteen RC servos from almost any robot controller or computer. The interface to the servo controller is a standard RS-232 serial port or a TTL-level serial line, using any baud rate between 1200 and 38400 baud. Multiple servo controllers can be connected to a single serial line, and they are compatible with our full line of serial servo and motor controllers, allowing an almost arbitrary number of servos and motors to be...

The Pololu micro serial servo controller (SSC) is a very compact solution for controlling up to eight radio control (RC) servos from a computer or microcontroller. The controller measures just 0.91in. x 0.91in., yet it is one of the most full-featured servo controllers available. Each servo speed and range can be controlled independently, the baud rate is detected automatically over a 1200-38400 bps range, and multiple units can be daisy-chained on one serial line to control up to 128 servos....
