Abstract: In early 2014, the school organized a approached the elderly and people with disabilities experience their emotions in caring activities, but also want to be more convenient for their lives and make their own efforts to understand our activities. that when an accident or illness, rescue stretcher is the most common tool used by many stretcher kind aid station, but the movement is still the traditional way people carry, push, in the event of special circumstances, such as earthquakes, terrorist attacks and in When the rescue of the wounded on the battlefield, traditional man lift, push in the rescue process is bound to the difficulties, rescuers own security will be threatened.

Early 2014, the school organized a approached the elderly and the disabled caring activities. In the experience of their emotions, but also want to be more convenient for their lives and make their own efforts.

Activities, we learned that when an accident or illness, rescue stretcher is the most common tools. Aid station using many different types of stretchers, but the movement is still the traditional man lift, push, in the event of special circumstances, such as earthquakes, terrorist attacks and rescue the wounded on the battlefield, the traditional person lift, push in the rescue process certainly difficult, rescuers own security will be threatened.

So, we decided to design an intelligent stretcher, services for the elderly and people with disabilities, especially in disasters such as earthquakes, terrorist attacks, war, etc., better rescue stranded elderly, the disabled and the injured.

First, the basic idea

Using traditional Lego robot kit to build a smart stretcher, first with Lego components built by four motor-driven vehicle frame, using RCX as the "brain" to realize the stretcher motion control, and then choose the ultrasonic detection module detects the road, through a level and linkage adjustment means so stretcher bearing surface has remained stable level, so lying on top of people suffer from bumps.

Second, the development process

1. First use Lego robot kit to build a four-wheel sports car robot. Use RCX as the "brain" of the motor to achieve the regulation. Adjusted by adjusting the robot touches the car sports such as forward, backward, turning and so on.

In front of the robot vehicle equipped with a camera as the "eyes", the scene of the shooting to be displayed directly on the computer screen.

2. We found that the shop has to sell an instrument called an ultrasonic module, so buy a set of modules, debugging using it to detect the road, if there is an obstacle in front of one meter within the range of ultrasonic module generates a current, we put the current received on the light emitting diode, making it light, and then perceived by photosensors, made by the RCX command based on the input photosensor. Car implement actions to circumvent obstacles or obstacle.

3. Install a spirit level in the body and the linkage means that the car driving on bumpy roads, through a level adjustment so that the stretcher has remained stable, so that lying on top of people suffer from bumps.

Through test for detection, intelligent stretcher only to achieve intelligent control of the road, but also the use of ultrasonic module detects road conditions, avoid obstacles or obstacle to implement actions in the force level, and the linkage means, when the car driving on bumpy roads, through Level adjustment so stretcher remain stable.
