SIR is controlled by a human inspector via wireless transmitter and a powerful battery allows for approximately three hours of run time on a single charge.
and control tasks (with the exception of a microcontroller for bundling sensor data) are executed on a base station that runs the Robot Operating system.
The robot uses four Sharp infrared distance sensors for edge and obstacle detection and an Invensense MPU 6050 IMU provides the operator with orientation data.
These sensors are used currently only for user feedback. The camera used on the robot is a Gopro Hero 3 where it serves as a demonstrator for a visual sensor.
It is assisted by three lights one pointing in the viewing direction while the other two illuminate the ground in a flat angle
The second system is a wireless video transmitter for the Gopro camera that is often used in model airplanes.

What can you do with 12 RC robots all slaved to the same joystick remote control?
or nanorobots our robots are programmed to behave as simple remote control cars and tuned to listen to the same frequency.
Lighter than a feather these ultrathin film-like organic transistor integrated circuits are being developed by a research group led by Professor Takao Someya
This prototype device is a touch sensor featuring a 12×12 array of sensors on a 4. 8 cm x 4. 8 cm circuit.
It is made up of two layers an integrated circuit layer and a tactile sensor layer. he new flexible touch sensor is the world thinnest lightest
and people cannot feel the existence of this device. I believe this development will open up a wide range of new applications from health monitoring systems wearable medical instruments
The integrated circuits are manufactured on rolls of one micron thick plastic film making them easily scalable and cheap to produce.
while retaining full functionality. his is a very convenient way of making electronics stretchable because you can fabricate high performance devices in a flat state
and place process. ith the development of these plastic electronics the possibility for flexible thin large area electronics has been realized.
and producing several units did we discover that the vibrating modes in the chassis caused by aerodynamic turbulence from the propellers saturated the onboard rate-gyroscope sensors
We successfully accomplished this using infrared transceivers mounted to each connection interface. However we later discovered interference issues
On top of this was need the to shrink the size of the electronics such that it would fit within the protected volume of the chassis. We were motivated by recent manufacturing possibilities in creating flexible printed circuit boards
We therefore had to redo parts of the design for a standard printed circuit board. There was also the suggestion to first fly the system using a 3d motion capture system for measurement feedback.
but kept most of the power and control electronics the same. Using some of the most recent advances in manufacturing technology the chassis was printed 3d this time around enabling us to design with very little fabrication constraints
which we tested using the rate-gyroscope sensors from Revision 1. Using two units and electronics from Revision 1 we tested the closed-loop behaviour around a single axis of rotation by mounting the two units on a horizontal pivot.
This alone required a few iterations of the chassis which in the end we managed to get right.
Designed from the ground upeach unit uses a single 32-bit 72 MHZ microcontroller to interface with all of the onboard sensors actuators and communication peripherals.
The same microcontroller is used also for performing all of the computation necessary for estimation and control there is no computation that is performed offboard.
in the case where external sensors are used (e g. 3d motion capture system) the data can be sent to the units over this wireless link.
An infrared distance measurement sensor is used for measuring the distance of a unit to the ground.
Units are also able to communicate with one another in plane at a distance using infrared wireless transceivers
Finally a high energy density Lithium-Ion Polymer battery is used to power all the electronics and actuators contained onboard.
The only information that a unit needs for flight is its local sensor data and its position with respect to the vehicle centre of mass.
when designing the chassis local sensor information provides a unit with a rough estimate of the vehicle tilt and altitude.
As shown in the video below you could use these sensors to control small robots navigating an environment even in the dark
To build the sensors the researchers align an array of microlenses an array of photodetectors

the chip completes the entire process, up to SNP detection. SNPS are variations in a single DNA base among individuals.
Testing is done simply by injecting the blood and a chemical into the chip and setting it in the testing system.
Then, a newly developed electrochemical sensor identifies SNPS while the DNA is dissolved in the chemical. o implement this system on one chip,
and make detection easy, the first thing we focused on was the actuators. This system requires a very small, powerful pump.
It is a real robot with many useful sensors, including two cameras (at the front and on the bottom), sonar, accelerometers, gyrometers,
Further, it already uses these sensors to achieve accurate onboard state estimation and (consequently) stable hovering.
A sensor called an Inertial Measurement Unit (IMU) measures Rezero tilt angle, which is used by an onboard stabilizing controller to compute what kind of motor action is required to keep the system stable.
It maps its own environment and uses an array of sophisticated sensors to autonomously move about a busy space without interfering with people or other objects.

Flexible electronics have come into the market and are enabling new technologies like flexible displays in mobile phone, wearable electronics,
and the Internet of things (Iots). However, is the degree of flexibility enough for most applications? For many flexible devices, elasticity is a very important issue.
For example, wearable/biomedical devices and electronic skins (e skins) should stretch to conform to arbitrarily curved surfaces and moving body parts such as joints, diaphragms, and tendons.
Although several researchers have explored diverse stretchable electronics, due to the absence of the appropriate device structures and correspondingly electrodes,
