Grisbot Hoop Capture Challenge
Grisbot not only maneuvers, now it can capture and retrieve objects. At any rate, I’m thinking of making a hoop capture challenge. Roughly, the hook device and the capture operation look like this: Because the hook automatically captures the hoop, … Continue reading
Progress Bug in Scratch
Instead of a conventional status bar to track the progress of the data transmission, I decided it would be more fun to make a ‘progress bug.’ The bug would look like the robot and march across the screen as the … Continue reading
Modifying Scratch Interface
Perhaps I’m trying to fix something that isn’t broke, but I thought I’d try to improve the Grisbot:Scratch interface. Instead of clicking an icon in the corner to go to the specific waypoint data, you now click the waypoint sprite … Continue reading

Rewiring the robot
BEFORE: AFTER: The robot simply stopped working. I had to strip everything down to the breadboard, then build back up again. Now it seems to be working once more.
Assembly line for robots
We hear all the time about robots on the assembly line. Well, here is an assembly line for robots. As my experience as a temp taught me, every assembly line begins with bins full of parts. In this case, the … Continue reading
