Version One ... I call it Vone.

[VOne]

This is my first attemp at a rover.  Based on the Lynxmotion Tri-Track, it has two 12 volt DC motors, controlled by the sabertooth 2X10 and, of course, the Axon, which is incredible.



It has three 7.2 volt 3000mAh batteries on board, and is only rolling at 60% speed right now, until I put the sonar on.  This initial setup has 2 forward looking IR's, and 2 bumper switches; but I have many more senors to put on.

Thanks a lot to this forum for getting me started!



Vone!

that tri-track sure is expensive.

This is my first "successful" robot.  I had a servo driven Basix Stamp SX, that ran out of IO room and memory way too fast, and it moved way too slow, then I bricked it; and put it away for a year.  Then I modified a 50 dollar RC tank (from radio shack) to be autonomous with a Infineon C167, but the "free" C compiler was only free up to 8K, then it was $3,000 for the full compliler, and the base was too loud and looked dumb- and my hand built motor controler was either all out fast (1) or stopped (0); so I put it away for a year.  But I couldn't stop thinking about building a robot - as a database .NET application programmer, I really enjoy programming something and seeing it move in reality - so I decided to throw money at the problem and just get it the way I want with out any wasted time, so I got the very expensive Tri-Track, the expensive motor controller, and it all just worked the way it should, which makes me happy.  There is even 90 dollars worth of batteries on it.

As I was typing that, there was a knock on my door and my voice sythensizer was delivered.  The speakjet ... I pretty excited to try that out.

Anyway, back to the work bench.

I've recently taken delivery of a SpeakJet and a TSS256 from www.speechchips.com to compare how its output compares with my own 'home made' speech synthesizer in the Member Tutorials (then I'll update the tutorial and post an Eagle schematic). The two chips are very simple to wire up together. You need an audio output stage (like the one in my tutorial) or www.speechchips.com can sell you an already made up board. Ken at speechchips has been very helpful.
