Eye, Robot (Part One)
I’m toying with the idea of a robot that can interact with its environment by pattern recognition. I thought the way to do this was with a raspberry pi computer. So I bought the computer and the pi camera from … Continue reading

The CRISP Revolution
Today I was thinking, “What are the fundamental technologies of the economy of the future?” And I came up with the following acronym: C – Computers. R – Robots. I – Internet. S – Solar (Power). P – (3D) Printers. … Continue reading

Converting a micro servo to continuous rotation
Say you want to build a small robot, but you soon discover that DC motors move too fast and geared DC motors are too expensive. Then you hear about servos. Servos are basically geared DC motors, and microservos seem just … Continue reading

From Scratch to Arduino Test Bed
In my last blog entry, I created a new graphical interface in Scratch for transmitting data to the microcontroller on the robot. Tonight I verified that the Scratch program is able to communicate via screen flashes with the Arduino test … Continue reading
Grisbot screen interface for light track
You know, time just flies when I’m doing graphic design. I sure wish I was good at it. Anyhow, the above screen shows the graphical interface (in Scratch) for programming the robot in ‘light track’ mode. 0a: Specifies the distance … Continue reading
Grisbot (S3) follows the light
Poor Little Grisbot S3, I misprogrammed it this morning and instead of going forward it went backward — and off the table onto the floor. Despite landing upside down, it worked all right once I unbent the photocell leads. Anyhow, … Continue reading
Introducing Foambot
In my continuing quest to drive down the cost of grisbot, I’ve had to reconsider using acrylic. The material costs $3, and then on a good day the local hackerspace charges $18 to cut it. And then depending on the … Continue reading
Grisbot Scratch Interface for Free-Form Mode
The idea behind free-form mode is that a user can design her own path, say on a sheet of paper, and then program the robot accordingly. Consequently, the programming page simply shows the waypoint icons lined up in rows and … Continue reading
Grisbot Scratch Interface for Udrive
Here is the graphical user interface for U-drive (not U-turn as I said yesterday). To put the robot in U-drive mode, click on the U icon, and then go directly to the communications page. Do not bother with the scales … Continue reading
Grisbot: U-Turn Mode
The idea is to once again program the robot by holding it up to the computer screen — but this time by analog rather than digital communications. (I call this U-Turn Mode because of the U on the screen, but … Continue reading
