ROBOTICS Module

Your ROBOTICS Mini Bots Construction Set contains the ROBOTICS 
module. This corresponds to a small computer – not nearly 
as powerful as a PC, but fully sufficient for the 
following control experiments. 
You cannot program the ROBOTICS module 
your self. Various programs are already 
permanently stored in the module. The program from the "teach-in 
mobile robot" is an exception. This program allows you to create a short 
motion program using the two buttons. The small slide switches allow 
you to select and run the program for the model you want to control.

Power Supply

The ROBOTICS module works 
only when it is connected to a 
9 V power supply. For this pur-
pose use the battery tray with a 9 V block battery 
either as dry cell or rechargeable battery. When 
connecting ensure that the polarity is correct (red 
= positive). When the module is suppled with 
power correctly, the green LED illuminates.

Inputs I1 - I3:

Outputs Motor M1 and M2: 

You can connect the fischertechnik 

sensors to these inputs. They provide 

information on the module. Two 

buttons and one trail sensor are 

available as sensors.

You can connect the XS motors to the 

two outputs.
