A Bot with Peripheral Vision   Message List  
Reply | Forward Message #22848 of 59745 |

Hello all,

I wanted to share a circuit that results in
a bot with a form of Peripheral Vision.

It's a Master/Slave form of the SC-Head.

The photo-diodes should be positioned across
the front of the bot with the ones marked
Far Left and Far Right mounted at a greater
angle off center than the ones marked left
and right.

I'm putting together a write up on the
circuit and will post it to my site as
soon as I can.

Hope you find it interesting.

So long,
Droidmakr

I'm not so sure about this one. It seems like a clever way to get around the lockup that SC-head pvores suffer from. Toggling the pdiodes bias voltage might...

... Hi, Cliff. Very nice design. By my quick analysis ... 1) Normal behaviour is both motors running "forward". 2) When the robot is pointing in the general...

... No appology needed. In fact thanks. You did a great job and I do not see any errors. My schematic may make it easier to assemble and wire but yours makes...

As a matter of fact, Cliff will remember earlier comments when discussing the Schmitt Comparator that apply here as well: the multiple Si diodes provide a...
