21st Century : Robotics : Honda ASIMO Robot
From Honda Motor Co.comes a new small, lightweight humanoid robot named ASIMO that is able to walk in a manner which closely resembles that of a human being.
One area of Honda's basic research has involved the pursuit of developing an autonomous walking robot that can be helpful to humans as well as be of practical use in society. Research and development on this project began in 1986. In 1996 the prototype P2 made its debut, followed by P3 in 1997.
"ASIMO" is a further evolved version of P3 in an endearing people-friendly size which enables it to actually perform tasks within the realm of a human living environment. It also walks in a smooth fashion which closely resembles that of a human being. The range of movement of its arms has been significantly increased and it can now be operated by a new portable controller for improved ease of operation.
ASIMO Special Features:
Smaller and Lightweight
More Advanced Walking Technology
Expanded Range of Arm Movement
Small & Lightweight Compared to P3, ASIMO's height was reduced from 160cm to 120cm and its weight was reduced from 130kg to a mere 43kg. A height of 120cm was chosen because it was considered the optimum to operate household switches, reach doorknobs in a human living space and for performing tasks at tables and benches. By redesigning ASIMO's skeletal frame, reducing the frame's wall thickness and specially designing the control unit for compactness and light weight, ASIMO was made much more compact and its weight was reduced to a remarkable 43kg.
Advanced Walking Technology Predicted Movement Control (for predicting the next move and shifting the center of gravity accordingly) was combined with existing walking control know-how to create i-WALK (intelligent real-time flexible walking) technology, permitting smooth changes of direction. Additionally, because ASIMO walks like a human, with instant response to sudden movements, its walking is natural and very stable.
Simple Operation To improve the operation of the robot, flexible walking control and button operation (for gesticulations and hand waving) can be carried out by either a workstation or from the handy portable controller.
Expanded Range of Movement By installing ASIMO's shoulder's 20 degrees higher than P3, elbow height was increased to 15 degrees over horizontal, allowing a wider range of work capability. Also, ASIMO's range of vertical arm movement has been increased to 105 degrees, compared to P3's 90-degree range.
People-Friendly Design In addition to its compact size, ASIMO features a people-friendly design that is attractive in appearance and easy to live with.
