3. In the last 30 years the
computer and electronics
have entered in all fields
of science.

1990-2000 Office period
2000-2010 Internet period
2010-2015 Mobile applications period
2015-2025 Artificial Intelligence period
2025-?
Robotic Period.
5. IT zone enables the
creation of opportunities
that become needs.
e.g.: mobile phone,
facebook
6.
7. In the future we will
witness the entrance of
Artificial Intelligence in
Lifestyle devices like:
TV, auto, home
appliances, etc…
8. Companies with Big
growth potential of
millions dollars in IT and
electronics can be made
with an investment of up
to $ 10,000
9. In just 15 years, Romania
th country in
became the 6
the world with most
programmers per capita
12. In the West it's easier to
create a job than to find
one vacant.
13. The software products
with millions of users are
in a small number.
The software
products with a small
number of users are
in a number of millions.
14. Development Mechanism
of IT companies
• Over 2,000,000 electronic components with free
support and turnkey applications.
• Can be purchased online in 3 days.
• Tens of thousands of products that can be made.
• Efficient laboratories up to $ 10,000
• Equipment that creates PCBs by $ 10,000
• Pick & Place machine $20,000 cost - manufacture
of small series of products.
• No. of people reduced to max 10.
• 500 products/day can be made (PCB assembly)
• The high rate of profit.
15. An inventor until invents
something new has to
reinvent the wheel a few
times
16. There is always a natural
way from simple to complex.
You can not impose overnight
"Let's do teleportation".
17. I am programming for more
than 9 years.
I had done 40 different projects.
I had been to more than 130
national and 18 international
contests about computer science.
18. My biggest challenge is
the building of a
driverless car that uses
Artificial Intelligence.
20. Current self-driving car
problems
• The current autonomous car problem is caused by
using a very expensive 3D Lidar ($ 75,000), with a
very high resolution. The 3D LIDAR is used to
recognize the environment and create a high
resolution 3D map. By using it, the car will take the
decision to avoid obstacles.
26. The algorithm is parallel and it was developed using a multi-threading solution.
The software generates a thread for each core. The images are taken from a topview webcam and are inserted in a synchronous queue. Then, each CPU core, after
finishing the last task, verifies whether there is anything in that synchronous
queue, and if yes it will take the new task from the queue. The operations with the
queue were done using critical sections
30. The 3D Lidar on the car
• The data is sent via RS232 serial port and the
following software is able to read it and to send the
3D Data to the supervisor software.
32. Electronic parts
of the 3D Lidar
There are only 6 electronic parts:
• Base microcontroller, driving stepper – LIDAR,
interface for RS232
• LIDAR microcontroller – fast convertor analogical
digital SPI, wireless transmitter
• Convert the ToF(Time of Flight) into an analogical
signal.
• Clock generator – 4 kHz, 0.001%, length of duration
~ 40 ns
• Pulsed laser generator, 35A/40-60 ns
• APD photodiode, comparator and high speed A
stable
33. Base microcontroller, driving stepper
– LIDAR, interface for RS232
This diagram shows the computer interface and stepper motor control. The
electronic circuit diagram contains a receiver that collects data from the
rotating LIDAR. The transmission is via a 2-GHz transceiver.
34. Convert the ToF(Time of Fly)
into an analogic signal.
The electronic circuit calculates the time difference between the pulse and
reception of the reflected signal from the target. For this I used a D flip-flop.
The resulting signal is integrated with a high-frequency integrator, then is
applied to a sample and hold circuit created from a switch CD4067 and a
repeater. The circuit returns a voltage proportional to the pulse duration.
35. kHz, 0.001%, length of duration ~
40 ns
Laser pulse transmission method is called Pulsed Laser and involves the use
of large currents in the tens of amperes of short duration, 40-60
nanoseconds, with a maximum repetition rate of 3 kHz. Ensuring optical
power level of 70 Wats. Energy is very high but because the pulse duration is
very short, the reflected signal is much higher than the ambient light. The
latest version uses an infrared laser OSRAM SPL 90-3, optical power 75
Watts, 35 Amperes.

40. Will be in the future
self-driving cars?
• The question should be rephrased in
“when will be”.
41. To do:
• With the award money from Intel I will buy a
low-cost pick and place machine. If my
prototype will be functional and I will get the
expected performance of my design will try
to buy a professional shooter with great
capacity.
• These machines will enable me to create
industrial electronic board for a massproduction.
