Beetle-Bot Demo - CH Ting
"I bought a Beetle-Bot Kit from Amazon for $59. It has an Arduino Uno board as a controller, with wheels, drivers, and lots of sensors. I got the wheels to turn under my 328eforth and I hope to port Don Golding's Whisker system to it, but there is no guarantee it will work. It is fun just to see wheels turn and LEDs flashing."

Microprocessors Speak with Many Tongues
From: Electronics - 12/09/1076

Microprocessor manufacturers may be putting a lot of energy into strengthening their software support functions, but the independent software houses are far from idle. In fact, you might say they are capitalizing on the situation. The high-level-language compilers they are producing for popular microprocessor chips actually run on the chip manufacturers' microcomputer development systems. FORTH Inc., Manhattan Beach, CA, for example, recently came out with a new high-level language called micro-Forth, which will run on the Intel microcomputer development system for the 8080, as well as on the RCA CDP 1800 development system. Just announced is a version for the 6800 to run on Motorola Semiconductor's Exorciser. The new language, the company says, cuts execution times by as much as 90% while also reducing memory needs.
