TI-83+ Robot from Norland Research
Posted by Eric on 2 August 2000, 03:43 GMT
Kevin FitzGerrell sent in a link about a new Calculator Robot from Norland Research. This robot uses a TI-83+ for controls, and allows a user to easily construct a TI-BASIC program that calls an assembly program to move the robot around. Pretty nifty stuff.

This is interesting, but not a new idea. David West built a robot and controlled it using a TI-86 in assembly language over a year ago. The interesting part is that they are trying to market it. At $89, it is pretty expensive for a hobbyist, especially for such a limited robot. One would learn a lot more by build it him/herself from scratch, and would probably save money as well. I found one quote to be particullarly funny:
"Compare this to other robot kits. You get a LCD graphic display, basic or assembly programming built in, a keypad, loads of programming information on the web, and plenty of memory. And you can write your programs on you desktop computer and download them into your robot quickly and easily."
Considering that the TI-83+ retails for $99 (although you can find it cheaper), that makes this an expensive robot. For $190 in parts, you could build a much nicer robot. Of course you wouldn't have an 83+ calculator with it, but who would want one of those anyway? :)

Cheaper to buy the parts at Radio Shack? I think not. From a similar bot I built:
2 R/C servos (Hitec HS-300BB) - $21 each, Foam model aircraft wheels (Kyosha 55mm) - $6.00 each, tailwheel and bracket - about $3.00, serial servo controller (Ferretronics FT639) - $20.00, misc items (ICs, perf board, caps, connectors, microswitches, bump switch arms, DB9 connector, battery box, resistors, wires, etc...) - about $20. My total -- $97, mostly at Tower Hobbies and Digi-Key.
Their $85.95 shipped sounds pretty reasonable for what you get (or else I wouldn't have sent the link). You can certainly build cheaper robots from scratch, but this is a reasonable price for a kit. Kits like these are especially convenient for people who's main interest in robotics is the software. If I was going to offer a product like this I'd want it to support most TI and HP calcs with serial I/O, but it's still pretty cool.

I hope you are using an Apple Computer, not that stolen Windows operating system:)
Goodness, you must be from the past! Radio Shack is now a cheap radio control car store, a stereo store, a cell phone store, a computer store? You should visit one today. They are not an electronics supply store any more. Got a part number from Radio Shack for a 2.5mm stereo plug for the link port? How about a LP2950 low drop out 5v regulator? You get the picture, hard to do much with what they keep in stock.
I guess I should of asked David West about building a robot using a Z80 processor in 1978 when I built my first one. But, I couldn't find him at the time. Al Gore had not invented the internet yet:)
And yes, if anyone is interested in building a robot by themself, just email me. I will give you a list of where to buy every componet, where to have the pc board made, how to program the PIC processor and where to buy any programmers and software needed. We will help you select a scope and any test gear you need. I will give you instructions on how to modify a servo for uses as a gear box. Plus, when you are done, we will get you up and building a small amplifier for sound, a ir range finder, a wheel encoder, a digital compass, sonar range finder, a battery level indicator, radio and inferred remote control, and anything else you think you want to build for your robot.
