prezentare, comunicaţii, leadership și lucrul în
echipă
Implicarea studenților într-un proiect
competitiv, distractiv și interesant
Deliver resources for the planning,
development and demonstration of a remoteexploration robot
Create academic educational opportunities for
students in computer science, electrical and
mechanical engineering
Provide important “life skills” educational
opportunities for students: planning, project
management, presentation, communications,
leadership and teamwork
Inspire students through the process by
providing a very competitive, fun and exciting
project

Li-poly batery
Lithium-ion polymer batteries, polymer lithium ion, or more
commonly lithium polymer batteries (abbreviated Li-poly, Li-Pol, LiPo,
LIP, PLI or LiP) are rechargeable batteries (secondary cell batteries).
Normally batteries are composed of several identical secondary cells in
parallel addition to increase the discharge current capability.

Temperature sensor
The
DS18B20
Digital
Thermometer provides 9 to 12–
bit
centigrade
temperature
measurements and has an
alarm function with nonvolatile
user-programmable upper and
lower trigger points. The
DS18B20 communicates over a
1-Wire® bus that by definition
requires only one data line (and
ground) for communication with
a central microprocessor.
Humidity Sensor
Pressure Sensor
The
HIH-40104020/4021
Series Humidity Sensors are
designed specifically for high
volume
OEM
(Original
Equipment
Manufacturer)
users. Direct input to a
controller or other device is
made possible by this sensor’s
near linear voltage output. With
a typical current draw of only
200
µA,
the
HIH4010/4020/4021 Series is often
ideally suited for low drain,
battery operated systems.
The MPX4115 series is
designed to sense absolute
air pressure in an altimeter
or
barometer
(BAP)
applications.
Freescale's
BAP sensor integrates onchip, bipolar op amp
circuitry and thin film
resistor
networks
to
provide a high level analog
output
signal
and
temperature
compensation.
MQ-2 Semiconductor
Sensor for Combustible
Gas
Sensitive material of
MQ-2 gas sensor is SnO2,
which
with
lower
conductivity in clean air.
When
the
target
combustible gas exist, The
sensor’s conductivity is
more higher along with the
gas concentration rising.
