Ok, VC has Motor control, Simply choose a Vision Template and build your
command stack using the RCX Motor control. The RCX cannot run normal RCX
code while VC makes use of the RCX, nor can the RCX pass sensor readings to
VC. VC does not down load the command stack program to the RCX. Instead VC
makes use of the IR Tower and sends the commands real time. So you need
"line of sight" when using the RCX to control motors with VC. You can
"Interlace" other RCX Sensors to the motion controlled by VC.
Example.
I have 1 RCX controlling the up/down motion of the head of my Robot - Motor
port A, this receives it's instructions from VC via the IR tower. RCX 2 has
a Rotation Sensor conected to the aforementioned drive system. When RCX 2
detects Rotational values, RCX 2 triggers one of it's Motor ports causing
the Head to turn Left/Right.
Also, I have used VC and one RCX in the following Manner.
I stand in front of the Robot. I extend my arm outwards, and move my arm to
the left, the Robot "sees" this and directs motor control to move it's Left
arm in the same manner. When I moved my arm to the Right, the Robot Moves
it's Arm to the right in the same way.
Limitations:
Real time, Line of Sight required between the RCX and Vision Command/ IR Tower.
No sensor inputs from the RCX to VC. unless you direct a motor port to turn
on a Light and set one of the vision fields to watch for light. - or rig a
motor to diplay color or cause motion.
Only the Three (3) Motors ports can be controlled from the RCX by VC.
RCX can only "Run" the current VC program in Real time, no programming or
use of the 5 program slots is supported.
Some of these things you may or may not know about VC, I would say that it's
a trully great inovation! One that has brought more life into My latest
Robot than I ever imagined! BUY ONE !!!!!
Please feel free to ask if you still have questions, but please be specific
because I'm not sure if you know some of these things or not. I rather be
helpful than be redundant.....
Good luck!!!
