Assistive ultrasonic distance measurement for wheelchairs

Results course “Embedded Systems
Single projekt 14/17

Distanzmessung für Rollstühle

The main system, a box with an Arduino, the power supply and a sensor, is placed under the foot rest of the wheelchair. It can be easily removed and replaced by means of circular hook-and-loop fasteners. All elements of the project are modular and are easy to attach, detach or replace. Additional sensors can be attached, the Arduino can be replaced and the power bank can be removed for charging or replacement.

The Arduino reads the values from the ultrasonic meter, calculates the distance and displays it on the LCD display. Additionally the RGB LED is lit in signal colors to visualize the danger of distance.

During the week of digitization from 9 to 13 September 2019, entrepreneurs will find out which (further) potential digitization could offer their company in the Emscher-Lippe region. The lectures will give a compact overview of the respective topic and there is time for discussing company-specific concerns with the speakers afterwards. In the digitization workshop in the ‘FabLab’, a high-tech workshop of the Ruhr West University of Applied Sciences, you can discuss your special challenges with scientists and jointly develop digital solutions using 3D printing and the like.

EL4 at REHACARE with own booth

REHACARE – the international trade fair for rehabilitation and care – will once again take place in Düsseldorf from 18 to 21 September 2019. Emscher-Lippe-hoch-4 will be present with its own stand this year.

We want to present the project and its goals to a broad public and establish new contacts.

During the fair we will present a virtual reality application for wheelchair users, the humanoid robot Pepper and various aids for people with disabilities. A 3D-printer and a 3D-scanner will be there as well to produce further aids on site.

If you want to visit us at REHACARE: You find us in hall 6 booth E09. We are looking forward to seeing you.

The Writi-Fi product allows the simple operation of a keyboard by simple hand movements. To confirm the keyboard entries, the hand just needs to be tilted upwards.

The aim was to build a simple system that offers an alternative to people who cannot use a keyboard. It addresses people who have difficulty making precise keystrokes. The various reasons that prevent the user from doing so, are irrelevant to the system as long as the user is able to tilt a hand. One of its biggest advantages of this system is the wireless connection to the computer.

CamRead offers the possibility to stream print media and documents to any output device in enlarged form. The camera position can be changed via a joystick.

It consists of two components: the frame and the joystick.

The two systems (joystick and camera shift) are each controlled by an ESP32 microcontroller. These are used as both are already equipped with Bluetooth by the manufacturer.

Smart Watering

Results from course “Embedded Systems”
Single project 11/17

Elderly persons often find it difficult to water their remaining houseplants due to their advanced age and problems with lifting objects, but they still would like to preserve their plants. Hence the idea to install a (semi-) automated irrigation system to facilitate irrigation of the plants was born.

There are numerous possibilities to provide such a system. The group decided to build a system based on small specifications, that has the possibility to run automatically after doing a few settings, but that can also operated manually. Some suggestions and ideas came up, which helped us to get a rough overview of which systems did not yet exist and how we could set ourselves apart from existing products.

Maja – Blood sugar monitoring system for the desk

Results from course “Embedded Systems”
Single project 10/17

People with diabetes need to check their sensors that measure blood glucose by hand with a reading device or a smartphone application to date. Thus the user is forced to retrieve the blood sugar value by hand constantly and to keep an eye on it. Children and disabled persons may not be able to interpret the values correctly ​​and draw the right conclusions.
