to move forwards. The setting on the potentiometer also has an effect
on the deviation caused by the trail sensor.
The trail sensor consists of two transmitter and receiver elements as
described under sensors. With the aid of these two transmitter and
receiver elements the trail sensor can recognize how the Mini Bot
makes contact with the black line acting as a hindrance and deviates
accordingly. When, for example, the transmitter and receiver elements
on the left side detect a black line first, the Mini Bot moves back while
deviating to the right. In this case the trail sensor activates the same
action as the mini-switches acting as sensors on the bumper.
You can also use the obstacle course from the construction set for the
hindrance detector model with trail sensor. For this purpose place the
Mini Bot in the middle of the obstacle course and switch on the power
supply on the battery tray. The Mini Bot then continues to move forward
until it touches a hindrance with the bumper or recognizes a black line
with the trail sensor.
Teach-in Mobile Robot
"Teach-in" is a concept from the world of robotics.
A wireless or cable type remote control is used
to move the robot to the desired positions, which
are then saved in a program. The robot then moves
precisely to these positions with the aid of the
program.
With the teach-in mobile robot you can program the
motion path yourself using the cable remote control integrated into the
model.
To program the teach-in mobile robot it is necessary to set DIP switches
1 and 5 to ON.
DIP switch setting for creating program:
