Each year, millions of adults aged 65 and older fall, causing injuries such as hip fractures and head trauma. This equates to about one out of every three adults aged 65 and older falling at least once per year. One of the benefits of using a walker is to help prevent these injuries. However, walkers do not prevent all accidents, and can even cause some. The Centers for Disease Control and Prevention (CDC) states that 47,000 elderly people are injured per year from cane or walker-related falls, and about 87% of the elderly falls are walker-related. In addition to causing falls, walkers also limit the mobility of the user. These issues inspired our idea of building a walker that could solve them. The two main goals of this project were to prevent falls and provide more mobility than the traditional walker.

The walker uses copper pipes and copper fittings, such as 90 degree elbows and tees, to make up the frame. The walker also uses a tilt sensor connected to a microcontroller, which detects when the walker is falling and triggers a motor to rotate the arm out, which prevents the walker from falling. The walker uses Omni wheels, which can roll forward, backward, and sideways, to provide mobility.

In conclusion, the walker's purpose is to assist the elderly in their mobility issues, as well as help prevent falls among them. These problems have been solved in our walker through the use of Omni wheels and a tilt sensor.

Step 1: Materials

15 feet copper pipe 1/2 inch diameter

10 1/2'' T connectors

4 ½” 90-degree elbows

4 3” omni wheels

1 servo or any other rotating motor

1 Arduino Microcontroller


1 Buzzer

1 box to hold the Arduino, LED, and Buzzer

1 metal rod less than ½ inch diameter

6 zip ties

1 9 volt battery

1 9V battery box/connector

1 9V battery to Arduino connecting wire

23 bolts and nuts

9 washers

2 triangular metal plates

1 rectangular metal plate

<p>Very interesting and a smart proj. Thanks for sharing here..</p>
<p>What is the reaction time of the system? How fast does it deploy the anti-fall arm?</p><p>It also seems like since the servo is directly connected to the arm, that any forces placed upon it will be transmitted back to the servo, which might damage it.</p>
<p>deployment of the anti-fall arm takes about 2 to 3 second depending on battery life. </p>
