Robot wars

4QD controllers have been used to a significant extent in the Robot Wars, which was first transmitted in March 1998 on British television and has been running ever since. The BBC's own house robots used 4QD controllers as did several of the competitors. Since then 4QD have probably supplied more contrrollers to Robot Wars than have any other company.

These sites may be of interest:

Technobots supply a radio control interface.
Team Delta
The Barry Web Site
R/C circuits and links to other sites.

Sites of general electronics interest:

Eugene Blanchard's description of MOSFET bridges. These are simple, non-pwm circuits (i.e. not variable speed) but should prove interesting.
Radio control circuits.

Computing related sites

4QD use Acorn computers. These are not 'industry standard' (whatever that is) but one thing is certain about 'industry standards' - if you wish to be better than the standard you have to lead it, not follow it.

Our own pages on RISC OS computing, and the differences.
ROUGOL (Risc Os Users Group Of London) home page with lots of interesting links. A good place to start finding out about Risc OS.
RISCOS Ltd who are now responsible for selling the OS software.
The Acorn Cybervillage is dedicated to RISC OS.
'Heard on the net', in the cybervillage, you may find diverting.
Performance benchmarks for computers, an interesting page with computer processing speed measurements. In view of Acorn's new StrongARM processor it is interesting to see how far up the chart this puts the RISC PC! Eat your hearts out, Pentium owners!
MicroSoft on Trial daily details of the Microsoft trial.
