Titan "The Amazing Robot"

Do you know anything just the world's smartest robot?

There are a lot of the world's smartest robot and one of them is

Titan robot.

Why is this predicate smartest robot on robot Titan?

And do you know how smart this Titan robots.

Well, now let's talk about these robots.

Titan robot is a robot designed to entertain the public. Designed and built by Cyberstein Robot Ltd in Cornwall, England.

Titan robot can sing, dance, speech, laughing, joking, entertaining anyone who saw it. Because the robot has incorporated sophisticated technology that has multiple personalities like humans.

Technology behind Titan

Titan himself is powered by the latest LiFePO4 (Lithium Ferrous Phosphate) batteries and can operate for up to eight hours on one charge. When back in the Cyberstein workshop Titan is continuously plugged into the Internet, where his vast solid-state memory both records and deposits information. (It is believed Titan has the biggest solid-state memory bank in the world). Many of the systems within Titan are the pinnacle of world development in their field.

It amazed when I saw the performance of this robot. If you imagine that there are robots in the Transformers movie comes the real life, perhaps a robot Titan is the answer. Because this robot has a height of 2.4 meters (7.9 feet) and weight 60 kilograms. High rises above an adult.

The robot is worth 7 million dollars, can only be hired if we want to look at our great events. Because there is only one of the world.

Titan robot so far has appeared in several countries including China, Hong Kong, Hollywood, and several countries in Europe.

If you're curious to see the action, see this video.

Make a Analog Line Tracer

To create a robot line tracer, we must first have a basic electro. In order to help us to understand each of the components to be used.
 Basic theoryfundamental component of robotic systems :1. Resistor 2. IC LM 3243. Led Superbright4. Variabel Resistor5. Transistor6. Photodioda7. Led Indicator8. PCB Matrix

Image circuit of Line Tracer :

Analog Line Tracer circuit above there are 3 main parts, namely the sensor, comparator and drivers. For the sensors used photodioda as light sensors, while its comparator using IC LM324 as a voltage comparator and to use H-Bridge driver transistors.

The workings of circuits Analog Line Tracer are as follows :
A. Sensors Working PrincipleThe sensor used consists of photo diode. This sensor resistance value is reduced when exposed to light and work on riverse refraction conditions. To use the LED superbright light sensor, this component has a very bright light, which is sufficient to supply light to the photodiode.

Image : Sensors Circuit

How it works :

Image : The sensor is not exposed to light

If the photo diode is not exposed to light, then the resistance valuewill be large or can we assume infinite. So that current flows into the comparator is very small or can be assumed with a logic 0.

Image : Sensors exposed to light

If the photo diode is exposed to light, the photo diode will be as a source of voltage and resistance value will be small, so there will be currents flowing into the comparator and logic 1.

B.Comparator Working Principle 

Comparator in this circuit using IC LM 324 which contains a series of Op Amp is used to compare the input from the sensors. Where input will be compared from IC LM 324 Op Amp which high pulsed output. So it is not necessary to pull up the output. This IC can workpad range 3 volts to 30 volts and can work with a normal starting voltage of 6 volts.

In this series there are also four LEDs, which serve as indicators. To set the voltage comparator, connected Variable Resistor (VR) between the two OP Amp IC LM 324. For the LM324 datasheet please download here.

Image : Comparator Circuit

• If no current flows from circuit to circuit sensor is the input voltage for this circuit is 0 volts, resulting in a voltage at IC terminal (+)> (-), theLED-A on, whereas in the opposite IC 2-LED B off.
• If there is current flowing from the sensor circuit to the circuit is the voltage input to the circuit is close to Vcc, resulting in IC voltage atterminal 2 (+) <(-), the LED-B on, whereas on the contrary the IC an LED-A off.

Conditions between points A and B will always invertibility.

C. Working Principle Motor Driver

Driver is a circuit composed of transistors used to drive DC motors.Where the main components are assembled according to the transistor characteristics.

Image : H-Bridgedriver circuit transistors

At the time of the input A logic 1, then there are currents flowing in the circuit, consequently the transistor 1 and 4 ar because it biases the base, so that the motor rotates. So when the input A logic 1 then the input B will be logic 0, so the transistor 2 and 3 will be off.

At input B logic 1, then there are currents flowing in the circuit, consequently the transistor 2 and 3 on that basis are biased, so the motor spins but in the opposite direction.

Symbian Anna (Symbian^3)

Symbian Anna - usability-focussed software update

Nokia today announced the forthcoming availability of Symbian Anna, a software upgrade for all Symbian^3 devices. The update is focused around three key objectives: delivering improved usability, enhancing enterprise functionality and improving developer productivity. The update underlines the importance of, and Nokia's ongoing commitment to, Symbian. Symbian Anna will ship with new devices later this quarter and be available to all existing Symbian^3 devices in a similar time frame.

Symbian Anna is effectively equivalent to PR 2.0, but does contain some elements (e.g. icon set) which were not originally envisioned for this. Nokia has already indicated that there will be future updates for Symbian. While no additional information was given, it is safe to assume more information on Symbian Bertie, Beatrice or Blondie will arrive later in the year. This would be equivalent to a PR 3.0 release. 

Nokia has chosen to move away from the firmware version number and PR scheme naming in public communications. Software updates are being given a nickname to allow for clearer communication, but it also reflects an increase in the significance and cadence of software updates.

What's in Symbian Anna?

• New fresh icons, delivered as part of a new theme. The icons are derived from the existing icongraphy, but with rounded edges, giving a more contemporary look and feel.
     
• Improved text input usability through the introduction of a portrait QWERTY keyboard and widespread use of split screen input. Split screen overlays text entry input boxes on existing screen elements and works in both portrait and landscape orientations. For example, in Maps a search can be entered and auto-completed results seen as you enter text. Similarly in Messaging, when you reply to a message in Conversations view you can see previous messages in the thread.
      
• Updated Web application with a more intuitive user interface and faster performance. This includes a standard location for the address bar at the top of the page (with improved auto-complete, which benefits from the new split screen text entry), visual back button accessible at all times (bottom left), and a redesigned and more responsive quick menu access floating button (bottom right). Performance of page rendering has been improved with an updated version of WebKit and improved scrolling and page navigation performance. The Web application continues to be based on the Symbian WebKit code base. A QtWebKit-based browser is likely to be one of the components delivered in the next software update.
      
• Ovi Maps 3.6, which is already available for existing devices (it recently graduated from Beta Labs). The major features in this version are improved search, public transport overlays to map view and the ability to download country maps on the device.
      
• Improved enterprise and security features. This includes the provision of six new security policies (for Microsoft Exchange), including enablers for the capability to turn encryption on remotely from Exchange device management tools. The update also includes Microsoft Communicator Mobile for corporate IM and presence (currently available via Ovi Store for selected devices).
      
• The latest version of Qt (4.7.3) and Qt Mobility (1.1.2), to improve developer productivity. This includes support for Qt Quick and a significant number of API improvements.
     

Symbian Anna roll out

The Nokia E6 and X7 will ship with the Symbian Anna update out of the box later this quarter. 

The Nokia Astound, the US version of the Nokia C7-00, has the majority of the software updates from Symbian Anna, with the exception of the new icon set. It will receive the remaining updates in due course.

New shipments of the Nokia N8, C7, C6-01 and E7 devices will come with Symbian Anna as standard in firmware later this quarter or next quarter. Depending on lead times and levels of retail inventory, the exact timing of this switchover will vary significantly from market to market.

Existing Symbian^3 devices (N8, C7, C6-01, E7) will receive the Symbian Anna update through a software update in Q2. Nokia would not give an exact timing for the update, but we would suggest a starting point some time in May for commencement of the update delivery process. The timing for the update will again vary from device to device and market to market. The roll out of the update will be done in stages, with different devices and different markets receiving the update in a staggered fashion.

In general, within a given model, SIM-free devices will be the first to receive the update. Operators may require additional checks and certification to be carried out, adding additional time to the delivery date. Nokia's broad intention is that all Symbian^3 devices should have received the update by this summer. This does represent a delay over previous commitments to PR 2.0. However, Symbian Anna does include some components not originally intended for PR 2.0 and Nokia noted that it wanted to focus on delivering a stable and competitive update.

We'll continue to update this story as we receieve additional information.
