Re: Roomba Clone Progress
- 360 PAN IS VERY USEFUL in navigation ,main reason can tell if a object is in back of the robot or on the sides

your Roomba robot using RoboRealm? I am thinking
of giving RoboRealm another look even if I only
use it to access the webcams. I have been using
escapi.dll to experiment with visual programs.
I have to work within my limitations when it comes
to electronics and programming. Shinsel's robots for
example requires above hobby level programming
abilities "expect that you need good Visual Studio
understanding to get it working." I am limited to
low level programming languages such as Assembler,
BASIC and C.
I have dumped the attempt at using the Roomba motors
and am back working on the old robot base although
it is somewhat overpowered in the motor department.
