GRIS Light Calibration
For some time now, the biggest roadblock to implementing my robot has been with screen communications. Now and then the path data transfer procedure works perfectly, other times it doesn’t work at all. I suspect it has something to do … Continue reading
LDR Cowling
This shows the gradual evolution of cowling solutions for the LDR. The presence of ambient light raises not only the zero level but also the break level between 0 and 1, so it’s been a headache to adjust the arduino … Continue reading
GIRC Robot Preliminary External Design
I’m still attempting to integrate the servo command sketch with the flash communication sketch, but I figure it’s time to start thinking about the external design of the robot. I plan to use a laser cutter on thin wood, with … Continue reading
GIRC Screen-Flash Communications
Worst demo ever, but these days I only have two hands. Here I needed three: one for holding the set-up, one for holding the camera, and one for clicking the mouse. Notice the status bar, also that there is a … Continue reading

GIRC Demo
On Saturday I made a brief presentation of GIRC at the monthly meeting of the Seattle Robotics Society. I demonstrated drawing the course and running it, as seen in the video above. Where to now? I want to program with … Continue reading
GIRC Robot Calibration Run
It’s Calibration Run Time here at GIRC Central. First we run GIRC and load in a path file of a square, fifty centimeters on a side, like so: We click Transfer and program the robot, then set it down on … Continue reading
Arduino reading screen flashes
I’ve upgraded the hardware to include two LEDs in addition to the phototransistor. Based on the reading of the screen flashes, the LEDs flash according to the key shown. Here’s a video of the system in action: This is at … Continue reading
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
