Zumo 32U4 Robot Kit (No Motors)

via Pololu - New Products

The Pololu Zumo 32U4 robot is a versatile tracked robot based on the Arduino-compatible ATmega32U4 MCU, and this kit contains most of the parts you need to build one—all you need to add are a pair of micro metal gearmotors and four AA batteries. It includes integrated dual motor drivers, an LCD, quadrature encoders, line sensors, side and front proximity sensors, and a full IMU. The assembled robot is less than 10 cm × 10 cm—small enough to qualify for Mini Sumo. This product is a kit; assembly (including soldering) is required.

SparkFun Inventor’s Kit (for Arduino Uno) – V3.2

via Pololu - New Products

The SparkFun Inventor’s Kit has everything you need to construct a variety of circuits that will teach you how to use an Arduino Uno to read sensors, display information on an LCD, drive motors, and more. No previous programming or electronics experience is necessary, which makes this a great way for beginners to get started with embedded systems. Version 3.2 adds a new Simon Says circuit with all the LEDs and tactile buttons needed to complete it.

Stepper Motor with 38cm Lead Screw: Bipolar, 200 Steps/Rev, 42×38mm, 2.8V, 1.7 A/Phase

via Pololu - New Products

This NEMA 17-size hybrid bipolar stepping motor has an integrated 38 cm (15″) threaded rod as its output shaft, turning it into a linear actuator capable of precision open-loop positioning. The included traveling nut has four mounting holes and moves 40 µm (1.6 mil) per full step; finer resolution can be achieved with microstepping. The stepper motor has a 1.8° step angle (200 steps/revolution) and each phase draws 1.7 A at 2.8 V, allowing for a holding torque of 3.7 kg-cm (51 oz-in).

150:1 Micro Metal Gearmotor HP with Extended Motor Shaft

via Pololu - New Products

This gearmotor is a miniature (0.94" x 0.39" x 0.47"), high-power brushed DC motor with 150.58:1 metal gearbox, similar to Sanyo’s popular 12 mm gearmotors. These units have a 0.365"-long, 3 mm-diameter D-shaped output shaft. This version also has a 4.5 x 1 mm extended motor shaft.

Key specs at 6 V: 200 RPM and 70 mA free-run, 40 oz-in (2.9 kg-cm) and 1.6 A stall.

1000:1 Micro Metal Gearmotor HP with Extended Motor Shaft

This miniature, high-torque gearmotor has a 986.41:1 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. This version also has a 4.5 x 1 mm extended motor shaft.

Key specs at 6 V: 32 RPM and 70 mA free-run, 125 oz-in (9 kg-cm) and 1.6 A stall. (Note: stall torque and current specifications are theoretical values; stalling the motor will damage the gearbox.)
