Grisbot Light Follow Test 2
In the following test, I have incorporated the light follow sketch into the general grisbot sketch. In other words, by using the graphical user interface written in Scratch, the user can either program the robot for following paths or for … Continue reading
Grisbot Light Follow Screen
In addition to the obstacle challenges, I’ve added a control screen to the GRIS program for light-follow mode. To get there, you click on the little flashlight icon at the top of the screen. In case my artistic abilities aren’t … Continue reading
Grisbot Light Follow Test #1
A little different from what I had in mind, but interesting: 1. When there’s low light, robot pauses two seconds, then spins. 2. When there’s high light, robot follows the light. Only the left photocell is being used here. I’ve … Continue reading
Light Follow Test Rig
With this test rig, I plan to write a sketch for grisbot that will cause the robot to follow a flashlight beam. There will be two states, Triggered and Non-triggered. The transition to from N to T occurs at a … Continue reading
Mic Check, some progress
On the left is a swatch of code that I wrote to read the analog input from the microphone circuit and print it to the serial monitor. On the right is the serial monitor. Under normal circumstances, the value read … Continue reading
Noise Meter Challenge
The Big Brained Superheroes Club has issued a challenge to build a noise meter, and so I thought I would give it a try. Hence I looked up a web page at the arduino site for building a noise meter. … Continue reading
Lessons Learned This Past Week
1. Cut the capacitor leads short so they won’t accidentally touch the photocell leads. 2. Fresh batteries make a big difference. 3. When masking tape is used to mark waypoints, a pipe-cleaner skid is prone to snag. 4. Do not … Continue reading

Grisbot Hoop Capture Test
I’ve got a bad feeling about this. Before we begin, some brief technical details: The orange pipe cleaner provides friction to compensate for servo swerve. *** The catcher is just a piece of wire. Nobody likes overengineering. *** More equipment … Continue reading
