GIRC test drive on blocks

GIRC (Graphical Interface for Robotic Control) is a ‘sketch’ written in Processing that enables user to draw a path file, save and reload, and transfer control codes to an Arduino-brained robot. The magnitudes of the turns and distances haven’t been … Continue reading

Disorganized workspace, organized mind (I hope)

Today I verified that the Arduino sketch still runs the servos, and then I did some organizing and planning. The note card on the left shows the listing for GIRC control codes (so far). On the right, I wrote out … Continue reading

Arduino Pin 13 as low-res serial monitor

Now that I have data to send from the computer to the arduino, I’d like to verify that it has gotten to the arduino. My original assumption was that I could echo back the data and read it on the … Continue reading

GIRC: Reviewing Output in the Processing Console

After I generate a path and convert the data into turn-and-move format, I want to send the data to the arduino-robot. For this I will use the USB/serial cable. But before I send any data, I want to make sure … Continue reading

GIRC Distance Commands

In the above illustration, the first Command Element has a command code of 44, which tells us that it is a Move command, and that we are to move 360 plus whatever is in the second Command Element minus 33. … Continue reading

GIRC Turn Codes

Here we make a 76 degree right turn in GIRC, and this information has to be sent over the USB/Serial cable to the microcontroller aboard the robot. This communication is done with a control code pair. As shown, the first … Continue reading

GIRC Path Data Conversion

The user inputs path data to GIRC by clicking points on the screen. Processing then draws segments between the points and calculates x,y coordinate data. This data is then converted into distance and turn data which will then be sent … Continue reading
