Chapter 1 – Control and Robots
1.1 Robots
The world today is a world of embedded computer systems. We find them in
mediasystems, watches, phones, remotecontrol, cars, and many more electronics.
A few years ago, we did not see terms such as wearable computing or internet of
things.
Everyday a surprising new product or application appears and months later, we
cannot realize how we lived without it. Modern systems are based more and more
on machine learning and artificial intelligence.
The robotic systems which are part of the embedded computer system, perform
independent activities such as: search, manipulation, identification, activation,
protection etc.
Many systems combine a certain kind of artificial intelligence in operating and
communication between machines.
The robotic system includes the controller, building components, wheels, gears,
motors, sensors, and more.
Each robotic system includes a controller that allows it to operate in accordance
with different operating programs. The robot developer writes these programs on
a computer and forwards them to the controller.
Building a robotic system creates a challenge to acquire knowledge in various
technology areas (electronics, computers, mechanics, electricity, etc.).
There are many types of robots such as arm robots, mobile robots, walking robots
and more.
The SENSE robots are a series of robots and "brain" units for study,programming
and making robots with wide variety of robot applications.
The sense autonomous is a robot enables us to program many robot applications
and functions such as movement on a line, movement along walls, tracking, AGV
(Automatic Guided Vehicle), autonomic car, autonomic guard vehicle, autonomic
taxi driver, environment monitoring, manipulating car and more. All these
applications are described as exercises in this book.

1.2 Control systems
A robot is a computerized control system.
A "Control system" may be defined as a group of components, which can be
operated together to control multiple variables, which govern the behavior of the
system.
Examples:
Air-conditioning systems control the temperature in the room.
A greenhouse control system controls temperature, humidity, light, and
irrigation.
A speed control system maintains a steady motor speed regardless of the
changing load on the motor.
A light control system can maintain a steady level of light, regardless of the
amount of available sunlight. The control system turns lamps ON or OFF
according to the requirements.
Three basic units are in every computerized control system:
1. Input unit – the unit that reads the system sensors like temperature, light,
distance, touch switch, etc. and feeds information into the control unit.
2. Control unit – the "BRAIN" of the control system, which contains the
system program in its memory and performs the program instructions and
processes the received data.
3. Output unit – the unit that operates the system actuators such as motors,
lamps,pump, and fan as the results of the inputs and theprogram "decisions".
Figure 1-1
The control unit is connected to a computer for programming and downloads a
program to the control unit flash memory.
Disconnecting the control unit from the computer and connecting a power source
such as a battery to it will create an independent system.

1.3 SENSE autonomous
SENSE autonomous is a mobile robot for applications such as:
Movement along black line or white line.
Movement along walls or in a labyrinth.
Autonomous vehicle such as: AGV, autonomous car, autonomous guard
vehicle, autonomous taxi driver, autonomous manipulator.
Following a moving body holding IR transmitter using tracking module.
Environmental monitoring and measurement robot with NeuLog sensors.
The SENSE autonomous has the following built in:
Base unit
3 connectors for NeuLog sensors or brain units
5 IR range sensors
1 line sensor
Pivot wheel
2 motors with wheels
A controller for the base sensors, motors, and independent operation
A flash memory for the user programs
USB connector for connection to PC or MAC
The sense autonomous comes with an adapter for external battery. Such battery
can be a standard Power Bank with USB outlet.
You may also have the NeuLog battery module BAT-202, which can
be plugged directly into one of the SENSE sockets.
When connecting such battery to the sense autonomous and
disconnecting it from the PC, the sense autonomous becomes an independent
robot running on its internal program in its flash memory.
In this book, we shall call the sense autonomous in short SENSE.

1.4 RobocklySense
The RobocklySense is a visual block-programming editor. It uses blocks that link
together to build a program instead of writing code texts.
The RobocklySense uses special blocks that can read the inputs, operate the
outputs, and read any of the data from NeuLog sensors.
The RobocklySense is very user friendly and it is easy to create and run robotics
programs.
1.5 RobocklySense installation
The software and drivers must be installed before connecting any modules
to the PC or MAC.
1. Download RobocklySense Application from: www.neulog.com.
2. Follow the instructions on the screen. The installation process is
straightforward and the required drivers are installed automatically.
The installation is composed of two parts: RobocklySense software installation
and USB driver installation. After the installation process is completed, the
RobocklySensesoftware is ready to use.
The RobocklySense shortcut icon should appear on the PC desktop.
Notes:
Upgrading the software can be done at any time. Installing the upgraded software
just replaces the relevant files, so uninstalling the software before upgrading is
not necessary.
During an upgrade, the software the USB driver installation can be skipped by
clicking the Cancel button.
