WebWrover Beta by Keith Daniel

WebWrover (Beta) by Keith Daniel & Donald Dolan

   * Tamiya model tank chassis
   * DC motor (pwm) plus servo clutch
   * 2 metre Amateur Radio all digital control link, 1200 baud
   * Colour video and audio return, camera on AZ/EL servos
   * Motorola 68HC11E9 inside, AS11 assembler code
   * Remotely controlled from handheld remote or Macintosh computer
   * Beeps on command
   * 12V nom. NiCad supply 5.1 A/Hrs.

The Beta is the succesor to the Alpha WebWrover, and has improvements to
the battery power supply. This version also returns colour video, as well
as audio.

The unit has been made modular, to allow easy modification of particular 
subassemblies. 

The camera mount was improved, and now includes a circular azimuth bearing and
balanced elevation coupling to the servo, to eliminate stresses to the
servo shafts.

We tried to implement a motor tachometer and digital PLL for improved user
control, however physical limitations made this impractical. 


The goal is to experiment with telepresence on the Web. Early experiments
with CU-SeeMe are encouraging, but point out bandwidth problems.

These are a collaboration between myself Keith Daniel VE2KXD
(ensign@infobahnos.com) and Donald Dolan VA3DIG (ddolan@inforamp.net).

Thanks to Richard Allix VE2ARW for the precision machining.
