Japan has stepped into the future with the release of a "robot suit" that can help workers lift heavy loads or assist people with disabilities climb stairs. The 15-kg battery-powered suit, code-named HAL-5, detects muscle movements through electrical signal flows on the skin surface and then amplifies them. It can also move on its own accord, enabling it to help elderly or handicapped people walk, developers said.

In the US tiny robots that can turn into any shape - from the replica of a human to a banana to a mobile phone - are being developed by scientists.

The new science of claytronics, which will use nanotechnology to create tiny robots called catoms, would enable three-dimensional copies of people to be "faxed" around the world for virtual meetings.

India doesn…gt;TM]t want to be left behind as well. Recently students of Seedling Academy Research and Development Centre in Jaipur have created a robot that can be remote controlled using a mobile phone…gt;TM]s keypad. Among other things, the robot can dance, trace a path, draw alphabets, cut grass and even race at an amazing speed!

Robot is an assortment of the latest technology available †` Bluetooth, Wi-Fi, FM, etc. It is a simple four-wheel based, DC (direct current) power controlled robot. The team used programming languages such as C, C++, VB, JAVA and assembly language.

A robot can be controlled in one of three ways. The first is Wi-Fi (Wireless Fidelity, a wireless networking standard). A chip reads information from another remote computer and transfers information to the robot device.

The second is Bluetooth. A Bluetooth-enabled mobile handset could transfer instructions to the robot with the help of a dongle attached to one of the ports on it.

Last is FM (frequency modulation, as in FM radio). A transmitter uses radio waves and the beeps of a telephone to give orders to the robot.

A robot can serve varied utilities. The camera attached to the laptop on its base could be used to take photographs of places where humans wouldn…gt;TM]t want to go. It is equipped with a paint container that it can use to draw alphabet on hoardings or cricket grounds. Its developers claim that it would also be able to detect mines with sensors attached to its base. The project was funded by the institute and cost Rs 1 lakh.
