RoboPi is also supported on Banana Pi, Banana Pro, Odroid C1, Odroid XU4, MIPS Create CI20

Why did you make it?

I designed RoboPi in order to let people build to build advanced robots using a Raspberry Pi for vision and high-level objectives (visual recognition, navigation) off-loading the hard real time control to a Parallax Propeller eight core RISC processor. RoboPi also provides eight channels of 12 bit analog input.

What makes it special?

RoboPi is special due to:

• adds eight RISC cores
• 24 "FlexIO"
• 8 analog inputs (12 bit)
• RoboPi C library (available on all supported platforms)
• RoboPi Python library (available on all supported platforms except MIPS)
• extensive RoboPi Build Manual
• extensive RoboPi User Manual
• RoboPi support forums

Each of the 24 FlexIO's can individually be configured as:

• digital input
• digital output
• servo output
• motor pwm output
• ultrasonic distance sensor (Ping, HC-SR04 etc)

RoboPi is supported with C/C++ and Python libraries on:

• Raspberry Pi Model A / A+ / B / B+ / Zero
• Raspberry Pi 3, Raspberry Pi 2 Model B
• Banana Pro, Banana Pi
• LeMaker Guitar
• ODROID C1, ODROID XU4

RoboPi is also supported on the MIPS Creator CI20 with a C/C++ library.

Projects using RoboPi

• Elf – 2WD Raspberry Pi Robot
• The Better MouseTrap Servo Tester

More detailed list of features:

• Parallax Propeller P8X32 eight core 32 bit Risc microcontroller running at 100Mhz
• Each of the eight cores provides up to 25MIPS as most instructions take only 4 clock cycles
• three ten-pin Mikronauts I/O module expansion connectors (P0-P7, P8-P15, P16-P23)
• 24 servo compatible headers on P0..P23 P0-P7 jumper selectable power from Pi’s 5VDC supply or external servo power supply P8-P15 jumper selectable power from Pi’s 5VDC supply or external servo power supply P16-P23 is powered by 5V from the Pi expansion header for sensors
• Screw terminal for providing external power for Servo connectors P0-P15
• 8 servo compatible headers for an eight channel 0-5V analog to digital converter, MCP3208 for 12 bit A/D conversion
• 512Kbit boot EEPROM for the Propeller
• On-board voltage regulation providing 3.3V with power on LED from the 5V on the Pi header
• 4 pin I2C expansion header for the Raspberry Pi
• 4 pin I2C expansion header for the Propeller
• 5 pin HCOM connector for use with PropPlug in stand alone operation (optional)
• mounting holes matching Rev.2 Model A and Model B
• Mikronauts EZasPi prototyping board can stack below RoboPi
• Mikronauts Pi Jumper can stack on top of RoboPi
• Mikronauts SchoolBoard ][ and other Propeller products are compatible with RoboPi
