Asuro programmable mini mobile robot

ASURO is a mobile mini-robot, completely programmable in C and especially developed for education at the German Aerospace Centre DLR, department for Robotics and Mechatronics. Assembly is easy for experienced electronic technicians and feasible for a novice. Except for the printed circuit boards (PCB) only standard parts for assembly will be used.

For programming we use freeware only. Therefore ASURO is exceptionally suitable as an introduction into processor-controlled hobby electronics, for projects in schools and universities, for studies and adult education centres. Special tools, which are freeware for private users, have been used for all electronic development phases and software design, proving how robots can be designed without using expensive tools or machines.

ASURO is equipped with a RISC-processor and two independently controlled motors, an optical line- tracer, six collision-detector switches, two odometer-sensors, three optical displays and an infrared- communication set for programming and remote control by a PC .
We must inform all users, ASURO is no toy and is not to be handed out to children under the age of three years, as they may swallow the dozens of small components. Please provide some batteries and start the assembly!

And yes: ASURO is another way of saying: “Another Small and Unique Robot from Oberpfaffenhofen!”

Peltier Thermoelectric Cooler

suppy power 12V (max 15.2V), 136.8W /~9Amp
max differen temperature 67 deg Celcius
size 40x40x3.4 mm
one side hot and the othe cool

TEC (Thermoelectric Cooler) units with preattached leads. When voltage isapplied, one side of the TEC will get cold while the other side will get hot (you can switch the voltage to flip the direction of the temperature difference), or you can use them in reverse to generate electricity.

These amazing semiconductor coolers get ice cold in minutes or heat to boiling by simply reversing the polarity. What you can use is for temperature regulation of diode lasers, but they can be used for numerous applications from CPU coolers to alternate power sources, or even for your own custom car drink warmer/cooler (power from cigarette lighter).

Peltier devices are commonly used in camping and portable coolers and for cooling electronic components and small instruments. Some electronic equipment intended for military use in the field is thermoelectrically cooled. The cooling effect of Peltier heat pumps can also be used to extract water from the air in dehumidifiers.

Peltier elements are a common component in thermal cyclers, used for the synthesis of DNA by polymerase chain reaction (PCR), a common molecular biological technique which requires the rapid heating and cooling of the reaction mixture for denaturation, primer annealing and enzymatic synthesis cycles.

The effect is used in satellites and spacecraft to counter the effect of direct sunlight on one side of a craft by dissipating the heat over the cold shaded side, whereupon the heat is dissipated by thermal radiation into space.

Photon detectors such as CCDs in astronomical telescopes or very high-end digital cameras are often cooled down with Peltier elements. This reduces dark counts due to thermal noise. A dark count is the event that a pixel gives a signal although it has not received a photon but rather mistook a thermal fluctuation for one. On digital photos taken at low light these occur as speckles (or "pixel noise").

Thermoelectric coolers can be used to cool computer components to keep temperatures within design limits without the noise of a fan, or to maintain stable functioning when overclocking. In fiber optic applications, where the wavelength of a laser or a component is highly dependent on temperature, Peltier coolers are used along with a thermistor in a feedback loop to maintain a constant temperature and thereby stabilize the wavelength of the device. A Peltier cooler with a heat sink or waterblock can cool a chip to well below ambient temperature.

A USB powered beverage cooler

Peltier devices are used in USB drink coolers/chillers, one of the latest addition to USB gadgets/toys. These devices are powered directly from the USB port and are said to keep drinks chilled, some can even keep drinks warm

Minoru 3D Webcam

The Minoru 3D Webcam is a single piece with two cameras spaced roughly the same distance apart as human eyes, for the stereoscopic effect. This creates an anthropomorphic look that means users tend to look into the eyes of the camera as they light up. The Webcam has a multi-position stand that can sit or stand on a desk, or perch on a monitor. Viewers wear special coloured glasses to see the 3D image, and five pairs are included. Minoru means “Reality” in Japanese, and it reflects how users feel about the 3D image. The Minoru can be used with Windows Live Messenger, Skype, AOL instant messenger, OoVoo and other video conferencing packages. The camera can also be used to take still pictures or record 3D video for YouTube. It can also be used as a normal 2D Webcam.
