New Project – Scorpion/OpenCV

Scorpion Side
I’ve had this Scorpion robot platform for a long time.  It was given to me by my uncle in the early to mid 1990’s is my best guess.  The kit was made by Rhino Robots in 1984.  From what I can tell they are still around though do not produce the Scorpion anymore.

Scorpion Orginal Board
The Scorpion was built around a Motorola 6502 controller, with the motor control offloaded to dedicated stepper drivers.  Since it was designed from the beginning to be a research tool, the motors, bumpers, lights, and sensors are completely separate from the processor board.  For this reason its very easy to add whatever processor board you want.  In the past I’ve built boards from some of the early Atmel 8-bit processors ( the AT90S1200 comes to mind ).  Later on I had an arduino board.

ManualManual- DatasheetManual - Code

Since this was developed long before the internet was common place everything is in there.  Datasheets, code, lengthy descriptions on how every system interacts.  I don’t know of any manuals that even comes close to the detail in the Scorpion’s manual.


Recently I got introduced to the OpenCV project by a fellow member of Makers in Manchester and needed a platform to play with it on.  To that end I decided I should be able to adapt the Scorpion to work well with that.   I’ve already fitted some cameras to the spot where it originally had a single CdS cell for ‘image’ sensing.  The plan for processing is to run the cameras and vision and control through a Raspberry Pi and an atmega 1284p for the motor control.   Ultimately I would like to build a single board system though, more like the original robot used.  Would make a good project to learn how to design boards around the ARM chips I would likely need for the OpenCV system, and possibly intregrate the motor control onto that same chip.



I neglected to really document the last few projects I have done.  Mostly out laziness but also I didn’t really feel they were all that interesting, basically just re packaging of existing tech/ideas into something useful for me.  You can find them on my thingiverse and G+.

New, better documented project coming soon!


Breakout Board for the Toshiba TB62212FNG

Published on June 19, 2014, by in Uncategorized.

Needed a bunch of H-Bridges for a project that I likely won’t move forward with, but I found this chip that has 4 H-Bridges in a really small package. It only comes in surface mount packages so I threw together a breakout board for the HTSSOP-48 version. Schematic and eagles files can be found here.
