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
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
Metric Blue Test Phase
A quick trip to Vetco this morning, and I got some 22uF ceramic capacitors to replace the electrolytics that I was using in Metric Blue’s circuit. The LED blinked on cue. Success! Then the screen read test was getting error … Continue reading
Grisbot in metric
I decided to completely redraw minigrisbot in millimeters instead of inches, and it went much, much faster. Friends don’t let friends design robots in English units. (Pouring ale is another matter.) But why re-design something that’s already designed? In case … Continue reading
Grisbot with new courses
Here are three obstacle courses, which can be selected by choosing the corresponding icon at the top of the screen: I’ve been thinking about adding different modes, such as following a flashlight beam. If you have any ideas for what … Continue reading
Assembling Goldie the Grisbot
Here are the parts laid out for ‘Goldie’ the Grisbot. I call her Goldie because her acrylic casing will be yellow, and ‘Yellowy’ doesn’t quite work as a name for a vivacious young lady. First step is to place the … Continue reading
Grisbot revisions for prototype 2
I plan to build the second prototype today, and here is what it should look like: Wheels will use rubber bands instead of gaskets (saving $1 each wheel): Holes in the lid will enable a wire ‘hoop catcher’ to be … Continue reading
Grisbot in Scratch with obstacle
A video demo of another challenge course with Grisbot: Here’s some detail on the screens:
Grisbot in Scratch Demo
You’ll have to view the video here, because for some reason Youtube has overwritten the embedded link for this video with the one for the obstacle video.
