Answer 1

Consumer
Gesture control / face recognition
People and pet recognition / -counting
Navigation of robots and drones

Industry
Factory automation and robotics
HMI gesture control
Use for mobile machines (e.g. agricultural )

Automotive
Driver assistance / occupant monitoring
Pedestrian, driver and vehicle safety
Comfort functions (e.g. gesture control)

Question 2

What is a ToF-Camera? (Company, IFM)

Answer 2

Time of Flight - Camera
By measuring
the time of flight of light, it is
possible to determine the distance
values at pixel level between the
individual pixels and the object.
Thereby, the 3D information is
generated without any detours in
real time. The best-known ToF
techology is known as PMD
(Photonic Mixer Device).
The PMD time-of-flight technology
ensures detection of scenes and
objects with just one image capture
of 23,232 pixels in three dimensions
and without motion blur. The scene
is illuminated by modulated,
invisible infrared light and the
reflected light hits the PMD sensor.

Question 3

What does the ToF Camera consist of? (Company, IFM)

Answer 3

1. Infrared LEDs
   Four high powered IR LEDs (830nm) illuminate the entire field of view of the
   O3D over a range of 0.3m to 5m and are protected by scratch-resistant glass.
2. The lens
   The lens determines the field of view for the O3D. 60° x 45° and 40° x 30°
   alternatives are available for best possible adjustment to the application.

3.Time-of-Flight-Imager
The pmd time-of-flight image sensor resolves the scene with 176 x 132 pixels. It
is also equipped with a patented extraneous light suppression that makes it
immune to changing light conditions in the application environment.

4.M12 Ethernet process data interface
The M12 Ethernet interface can be used both to set the parameters of the
sensor and for communication of outgoing data via industrial Ethernet networks
(TCP/IP & EIP). The parameters are set using the freely available ifm Vision
Assistant.

5. M12 power supply
   The 8 pin M12 connector is both for power supply of the sensor and an interface
   for the digital and analogue outputs.

Question 4

What is IO-Link? (Company, IFM)

Answer 4

O-Link is the first
standardised IO-
technology (IEC
61131-9)
for communication with
sensors and actuators

Question 5

What is IODD? (Company, IFM)

Answer 5

Input Output Device Description - An IODD file is a description of the IO-Link device. It contains sensor parameters, mapping and other
information.

Question 7

Describe the characteristics of Smart Assembly Robotics (Company:Siemens)

Answer 7

• Force sensing / vision robotics

• Smooth transition from manual
  to robotic

Question 8

What was said about the development lead time in automotive industry? What is the current lead time for Volvo now?

Answer 8

The lead time get shorter. Currently 30 months

Question 9

What safety function does YASKAWA apply for COBOTS to avoid harming humans

Answer 9

Retract function
* Detects clamping situations
* Fast reaction to prevent physical injuries
* Immediate retract motion to reduce
occurring force and pressure

Clamp release function
* Second retract movement enables operator
to free himself
