Grisbot One-Click Transfer
I have been going with three buttons for the transmit procedure because I needed to calibrate light and dark rectangles before I could read the data. That made it cumbersome and confusing to use the transmit procedure. Here’s how the … Continue reading
Grisbot goes into the light
At the Big-Brained Superheroes Club.
Batteries: A Cautionary Tale
On Saturday, I took grisbot to the Seattle Robotics Society meeting and showed a demo video of the light-follow mode. After the main presentation, I got out grissy and tried to set up a real-time demo in case someone wanted … 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
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
Variations on a brushbot
In my continuing efforts to find a simple product to market, I thought, “Why don’t I make some upgrade mods to the conventional brushbot?” So I ordered a brushbot kit from Maker Shed, and modified as shown. The long green … Continue reading
Weighing Robotics
Some weights that are interesting to know. Display has one decimal place, so that 442 = 44.2. The display does have a decimal point, but it doesn’t show at the angle of the photos. Sorry. This is an Uno R3. … Continue reading
Grisbot with Arduino
Here is a preliminary design of a dual tray assembly that can carry both an Arduino and a mini bread board: Here’s an underview, showing how it all fits onto the robot body: As is, the tray assembly can’t be … Continue reading
