Abstract
In recently years, the needs of wheelchairs are increasing, since the activity of handicapped persons was increased. A person feels difficulty to pass through a slant space. The most place of outdoors is slanted for water drainage. In this report, we developed a power-assisted wheelchair to adapt to cancel the effect of the gravity caused by the slanted places. This wheelchair has a computer for control with the gyro to sense the inclination of the grand, two force sensors for measure the humans operational force and two motors to move the wheels. This wheelchair has also the battery for the system. Then this wheelchair is work autonomously except the data logging system.
