Want to build a small robot that doesn’t look like a PCB on wheels? The Orangutan is small enough for integrating into a small robot, rather than being the small robot. With a powerful Atmel mega168 AVR microcontroller, motor drivers, buttons, display, and buzzer, all you need to add is your own chassis, sensors, software,… you know, the fun stuff!
Note: The Orangutan SV-168 has been replaced by the Orangutan SV-328, which uses the newer ATmega328P microcontroller to provide 32 KB of program memory, 2 KB of RAM, and 1 KB of EEPROM. The ATmega328P is essentially a drop-in replacement for the ATmega168, so the code that works on the Orangutan SV-168 should work with minimal modification on the Orangutan SV-328 (the Pololu AVR Library now supports the ATmega328P).
The Orangutan SV-168 robot controller is a complete control solution for small robots running at 6 – 13.5 V. The small (2.15" x 1.9") module includes a powerful Atmel ATmega168 AVR microcontroller, two bidirectional motor ports each capable of providing 1 A (continuous), a removable 8-character x 2-line liquid crystal display, a buzzer, three user pushbutton switches, and two user LEDs.
Eight general-purpose I/O lines with up to eight analog input channels allow for adding sensors or expanding the system. These lines are brought out to 0.1" female headers as shown in the picture below; from left to right, the bottom row of pins are: PC5, PC4, PC3, PC2, PC1, PC0, PD1 and PD0. The Orangutan SV-168 features a 5V switching regulator capable of delivering up to 3 A, allowing the Orangutan to power RC servos directly from its regulated 5V power bus. This power bus can be accessed through the power and ground pins dedicated to each user I/O line.
The Orangutan SV-168 is based on Atmel’s mega168 AVR microcontroller, which runs at 20 MHz and features 16 Kbytes of flash program memory, 1024 bytes of SRAM, and 512 bytes of EEPROM. Because the user has direct access to the microcontroller, any development software for Atmel’s AVR microcontrollers, including Atmel’s free AVR Studio and the WinAVR GCC C/C++ compiler, is compatible with the Orangutan SV-168. An in-circuit programmer, such as our USB AVR programmer, is required for programming the Orangutan SV-168. We provide an extensive set of software libraries that make it easy to interface with all of the integrated hardware. These libraries come with a number of sample programs that demonstrate how to use the various components on the Orangutan SV-168. This robot controller is also compatible with the popular Arduino development platform.
Improvements over the Original Orangutan
The Orangutan SV-168 has introduced a number of substantial improvements over the original Orangutan, the most significant of which is the enhanced power system that allows an expanded operating range of 6 – 13.5 V (meaning you can power the Orangutan SV-168 from a 12 V battery), delivers higher motor current, and has much more available current on the 5 V line. The following list details the major changes:
