generate electricity. A phototransistor can be understood as a combination of a mini solar cell and a
transistor. Light impulses (photons) received by the phototransistor generate a very low current that is
then amplified by the transistor.
Note:
Please make sure the polarity is correct before connecting the phototransistor: Red marking = plus pole.
Maximum voltage: 30V max
■ We can connect different sensors and actuators to the ROBO Interface and interpret them. In addition
to 8 digital input terminals the ROBO Interface also offers several analog input terminals. For example,
a resistance value between 0 and 5,5 kΩ applied to the input terminals AX and AY is
converted into a numerical value between 0 and 1024. The measured values of a
brightness sensor, such as a phototransistor, can so be acquired and are
available for further processing. Voltages between 0 and 10VDC can be
measured at the analog input terminals A1 and A2.
The most important role of the Interface lies in the logical connection of the input
values. The Interface needs a program to do this. The program decides in how input
data and sensor signals are processed to generate appropriate output data, motor
control signals, etc. With the ROBO Interface we have enough computing power at our
disposal to design even the most sophisticated programs.
■ A graphical programming interface provides us with the most effective
way to create the necessary programs for the ROBO Interface. The term
"programming interface" stands for a software that enables us to create our
programs in a very comfortable way, using graphical symbols. Actually, the
computer of the ROBO Interface can only execute commands contained in its
so-called machine instruction set. These are essentially simple control
structures that are extremely difficult to use for beginners. That's why the PC
software ROBO Pro uses graphical elements that are later translated into a
language that can be executed by the Interface.
■ The only thing you need in addition to the ROBO Mobile Set is the Accu
Set. It contains the battery pack serving as mobile power supply for our robot
models and a special charger for the battery pack.
It would be best to start charging the battery pack right away using the
charger. This way it will be fully charged when we want to start
experimenting.
