What is it?

RoboPi is an advanced robot controller for Raspberry Pi (A/A+/B/B+/Z/2/3) and other SBC's

• Photo 2: RoboPi kit of parts (what you get)
• Photo 3: RoboPi mounted on a Raspberry Pi Model A
• Photo 4: RoboPi sandwich consisting of RoboPi, EZasPi, Raspberry Pi Model B, EZasPi (B)

PLEASE NOTE: RoboPi is supplied in kit form, you will have to assemble it yourself

RoboPi Lite KIT DOES NOT INCLUDE the P8X32A microcontroller and MCP3208-I/P ADC, you will have to purchase those parts separately if you don't already have them. RoboPi requires those parts to function, this listing is for those who alread have or wish to purchase those parts separately.

Photograph shows an assembled RoboPi for illustration purposes, you will receive a kit

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

PLEASE NOTE: RoboPi is supplied in kit form, you will have to assemble it yourself, and the Lite Kit requires the addition of a P8X32A-D40 and MCP3208-I/P integrated circuits.
