Re: RobotOpen Control Shield for Arduino
This shield works with:
Arduino original and UNO with or without an Ethernet shield and with the Arduino Ethernet pictured. To explain the system further; the RobotOpen Control Shield comes paired with a complete operator interface program that works out of the box with most USB joysticks on Linux, Windows and Macs. This communication is based on our RobotOpen Protocol. It is handling the heavy lifting when it comes to wifi and data transmission. If you wanted to keep your 2011 FRC bot running without a cRIO you could replace the cRIO with this system. You'd then follow these steps: 1: Provide the Arduino power, Ethernet and plug in the 37 pin connector to your sidecar. 2: Install the dashboard app on a computer 3: Plug in a USB joystick 4: For many robots, including Kitbots you'd be ready to drive provided you have your pwm's in the same ports that are mapped in our provided software. You'd have basic driving capability. For teams with more advanced needs the Arduino must be programmed for features above and beyond basic driving. The Arduino is quite powerful and could be used to replicate a complete robot system. The beauty of this product in my eyes is the ease of use with respect to wireless communication. And unlike some similar products in the market place RobotOpen is "open.". The RobotOpen Protocol was designed from the ground up to be expanded, tweaked and toyed with! ![]() |

Re: RobotOpen Control Shield for Arduino
What's the chip on the shield? Is it another atmega328? If so, how do they work together?

Re: RobotOpen Control Shield for Arduino
Yup, it's another atmega328. It's actually providing the signals for the PWM channels since the Arduino alone doesn't have enough I/O. It also enables/disables all outputs...sort of like a coprocessor. The Arduino sends all of the PWM positions over serial in addition to a checksum to ensure the integrity of the data.
We'll be publishing the spec for how this all works shortly. Believe it or not the atmega is actually cheaper than a PWM IC! |

Re: RobotOpen Control Shield for Arduino
For anyone who may have missed our advertising sprint at the start of the season we have a very detailed introduction video of the RobotOpen product and protocol available on our website.
RobotOpen Demo Video There was enough interest in our initial offering to continue developing new hardware and interface concepts...a tablet based operator station is in testing now as well as video support! Thank you to everyone who has been excited about the development of this product. We appreciate the support. ![]() |

Re: RobotOpen Control Shield for Arduino
Myself being one who speaks Arduino like a second language, I was excited to read about this! Is there a place I can access documentation such as source code and schematics? Thanks!

We are adding new information as soon as it is available. The board schematic should be there, but I see that it is not...we'll get it posted. |
