■ The ROBO Interface offers many more functions than discussed previously with the mobile robots. But
you will need additional components that are not included in the construction kit to take full advantage
of them. But since they offer very interesting options for the robots we now want to introduce a few of
them here.
■ The ROBO Interface has an infrared receiver diode for the handheld transmitter included in the IR
Control Set Art No. 30344. This enables you to query the buttons on the transmitter in the ROBO Pro
software as digital inputs and so for example turn motors on and off.
We have programmed a remote control for the walking robot as a sample program. With the 4 oval
arrow buttons on the remote control you can make the model go forward, backwards, to the left and to
the right. You only have to load the program Walking Robot IR.rpp into the Interface to get started.
Another ingenious program in connection with the remote control is the program Mobile-Teach-IR.rpp.
Using this teach-in program you can control a wheeled robot, e.g. the Simple Robot or the Basic Model.
The model will remember the path it traveled and will then be able to repeat it as often as you want it
to. But once the program is stopped this saved path will be erased.
It is the "List" program element in ROBO Pro that makes such a program possible. Many values can be
stored in this element and then called up again (please also see the ROBO Pro manual). The program
itself might be pretty complex but using it is very simple:
1. Load the program Mobile-Teach-IR.rpp into the Flash memory of the ROBO Interface and start it.
2. Press the M1 / button on the remote control. This starts the "learning process".
3. Use the oval arrow buttons to steer the model into the desired direction.
4. Press the M2 / button. This will save the path the robot traveled.
5. Press the M3 / button. This will make the robot travel along the saved path.
With an application like this, the programming of robots is a breeze! You should note that the saved path
will be erased as soon as you stop the program with the Prog button on the Interface.
■ The radio interface ROBO RF Data Link Art No. 93295 replaces the interface cable between PC and
the Interface with radio data transmission. This is a fine thing indeed. First of all you won't have to keep
connecting and disconnecting the cable each time you load a program into the Interface. Secondly, you
will be able to run programs wirelessly in online mode. This will make it much easier to find errors than
with the regular download operation. And finally you will be able to control the mobile robots in online
mode on your screen using a panel in ROBO Pro, similarly to using the IR remote control. But differently
from the remote control, the screen additionally displays the data provided by the interface such as
values of variables or analog inputs, supply voltage from the battery pack and speed of the motors.
