Pololu 3pi robot [https://www.pololu.com/product/975]: a mega168/328-based programmable robot.

The 3pi robot essentially contains an SV-328 and a 5-sensor version of the QTR-8RC, both of

which are in the list below.

Pololu Orangutan SVP-1284 [https://www.pololu.com/product/1327]: based on the mega1284, the

SVP-1284 is our newest Orangutan robot controller. It is a super-sized version of the SV-328,

with a built-in AVR ISP programmer, more I/O lines, more regulated power, and more memory.

It also features hardware that makes it easy to control up to eight servos with a single hardware

PWM and almost no processor overhead.

Pololu Orangutan SVP-324 [https://www.pololu.com/product/1325]: based on the mega324, the

SVP-324 is a version of the SVP-1284 with less memory. The two versions are completely

code-compatible (the same code will run on both devices as long as it’s small enough to fit on

the ATmega324PA).

Pololu Orangutan X2 [https://www.pololu.com/product/738]: based on the mega1284, the X2 robot

controller is the most powerful Orangutan. It features an auxiliary microcontroller devoted to

controlling much of the integrated hardware (it also acts as a built-in AVR ISP programmer)

and high-power motor drivers capable of delivering hundreds of watts.

Pololu Orangutan SV-328 [https://www.pololu.com/product/1227]: a full-featured, mega328-based

robot controller that includes an LCD display. The SV-328 runs on an input voltage of

6-13.5V, giving you a wide range of robot power supply options, and can supply up to

3 A on its regulated 5 V bus. This library also supports the original Orangutan SV-168

[https://www.pololu.com/product/1225], which was replaced by the SV-328.

Pololu Orangutan LV-168 [https://www.pololu.com/product/775]: a full-featured, mega168-based

robot controller that includes an LCD display. The LV-168 runs on an input voltage of 2-5V,

allowing two or three batteries to power a robot.

Pololu Baby Orangutan B-48 [https://www.pololu.com/product/1215]: a compact, complete robot

controller based on the mega48. The B-48 packs a voltage regulator, processor, and a two-

channel motor-driver into a 24-pin DIP format.

Pololu Baby Orangutan B-328 [https://www.pololu.com/product/1220]: a mega328 version of the

above. The mega328 offers more memory for your programs (32 KB flash, 2 KB RAM). This

library also supports the Baby Orangutan B-168 [https://www.pololu.com/product/1216], which was

replaced by the Baby B-328.

Pololu QTR-1A [https://www.pololu.com/product/958] and QTR-8A [https://www.pololu.com/product/

960] reflectance sensors (analog): an analog sensor containing IR/phototransistor pairs that

allows a robot to detect the difference between shades of color. The QTR sensors can be used
