New Website Launched

We launched the new Pololu.com website in February, bringing many needed features:

• Product pages with pictures, resources, FAQs, and other information to help you find what you need for your project.
• Fast checkout with secure credit card processing. Choose between entering your credit card information on our site or paying with your PayPal account.
• Secure account access with tracking information for your current order and a record of your entire order history. If you have ordered before, an account was automatically created for you, so don’t forget to log in and check it out.

We’ll be constantly adding new features to make the site more efficient and personalized for you.

Robotics Forum Continues to Grow

There’s been a lot of great discussion recently about building robots on the Pololu robotics forum at forum.pololu.com. Whether you want basic electronics help, advice about which parts to use for that next robot project, or technical support for Pololu products, ask a question here and someone will probably answer it within a few hours. Post pictures of your latest project and everyone will get to see what you’ve been working on!

Featured Products

Pololu Ball Casters Our ball casters are great third contact points for small differential-drive robots. These units have larger ball diameter-to-weight ratios than industrial units, giving your robot the ability to drive over larger obstacles without adding too much weight. Several sizes and ball options are available.

Robot Kits without Soldering Beginner to advanced kits that do not require soldering.

Orangutan X2 Robot Controllers The Orangutan X2 is the most powerful member of our Orangutan robot controller line. It is available with the VNH2SP30 or VNH3SP30 motor drivers and with or without a 4-line x 20-character LCD.

	New! Pololu part #: 958 Price: $3.49 Quantity:
QTR-1A Reflectance Sensor The QTR-1A reflectance sensor carries a single infrared LED and phototransistor pair in an inexpensive, tiny 0.5" x 0.3" module that can be mounted almost anywhere and is great for edge detection and line following applications. The reflectance measurement is output as an analog voltage.

QTR-1RC Reflectance Sensor The QTR-1RC reflectance sensor carries a single infrared LED and phototransistor pair in an inexpensive, tiny 0.5" x 0.3" module that can be mounted almost anywhere and is great for edge detection and line following applications. The output is designed to be measured by a digital I/O line.

	New! Pololu part #: 960 Price: $14.95 Quantity:
QTR-8A Reflectance Sensor Array This sensor module has 8 IR LED/phototransistor pairs mounted on a 0.375" pitch, making it a great detector for a line-following robot. Pairs of LEDs are arranged in series to halve current consumption, and a MOSFET allows the LEDs to be turned off for additional sensing or power-savings options. Each sensor provides a separate analog voltage output.

100:1 Mini Metal Gearmotor This high-quality metal gearmotor is a compact (1.66" x 0.46" x 0.60") motor with an enclosed 100:1 metal gearbox. These units have a 0.275"-long, D-shaped output shaft, and they are intended for 4.5-6 V operation.

	New! Pololu part #: 991 Price: $17.95 Quantity:
24:1 Mini Metal Gearmotor This high-quality metal gearmotor is a compact (1.66" x 0.46" x 0.60") motor with an enclosed 24:1 metal gearbox. These units have a 0.275"-long, D-shaped output shaft, and they are intended for 4.5-6 V operation.

	New! Pololu part #: 992 Price: $15.95 Quantity:
100:1 Micro Metal Gearmotor This gearmotor is a miniature (1.42" x 0.39" x 0.47"), high-quality motor with 100:1 metal gearbox, similar to Sanyo’s popular 12 mm gearmotors. These units have a 0.365"-long, D-shaped output shaft, and they are intended for 4.5-6 V operation.

	New! Pololu part #: 993 Price: $15.95 Quantity:
30:1 Micro Metal Gearmotor This gearmotor is a miniature (1.42" x 0.39" x 0.47"), high-quality motor with 30:1 metal gearbox, similar to Sanyo’s popular 12 mm gearmotors. These units have a 0.365"-long, D-shaped output shaft, and they are intended for 4.5-6 V operation.

	Pololu part #: 775 Price: $59.95 Quantity:
Orangutan LV-168 robot controller The Orangutan LV-168 is a full-featured controller for low-voltage robots. Thanks to a step-up voltage regulator, you can power this Orangutan with two or three 1.2-1.5 V batteries while maintaining 5 V operation for its Atmel mega168 AVR microcontroller and your sensors. A pair of discrete, low-voltage H-bridges deliver up to 2 A continuous to get the most power out of low-voltage motors.

	Pololu part #: 777 Price: $99.95 Quantity:
Pololu TReX dual motor controller DMC01 The TReX blends RC, analog, and serial inputs for a powerful motor control solution. The TReX will work right out of the box as an electronic speed control (ESC), but its ability to seamlessly transition between RC/analog and serial control makes it capable of so much more!

	Pololu part #: 767 Price: $59.95 Quantity:
Pololu TReX Jr dual motor controller DMC02 This lower-power, smaller, and lower-cost version of the TReX is the ultimate general-purpose motor controller for small motors: it has a wide operating range (5 to 24 V), delivers 2.5 A continuously per motor, provides current sensing on the two main channels, and it features the TReX triple interface that allows you to control motors from a serial line (RS-232 or TTL), radio control (RC) receiver, or analog voltage source such as a potentiometer.
