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.

Results course “Embedded Systems”
Individual project 9/17

Users who rely on a wheelchair have additional requirements for visual perception. If there is no possibility of direct contact with the ground and the wheelchair is large and motorized, the field of vision is severely restricted. The safe navigation around obstacles such as bumps or curbs is not easily possible.

Opening of the Mini-FabLab in the Rheinbaben workshop

A further contribution to one of the main objectives of the Emscher-Lippe-hoch-4 project has been made. The Mini-FabLab in the Rheinbabenwerkstatt of the Bottroper Werkstätten was successfully opened.

We have installed several computers, 3D printers and a vinyl cutter in a wonderfully furnished room in the Rheinbabenwerkstatt. The technology is now available to all employees on site. People with disabilities can produce aids independently for their everyday life and their workplace.

Dosieromat – dosing device

Results course “Embedded Systems”
Single project 8/1

The dosing device is used for the automatic dosing of certain ingredients, in particular bulk materials. The material is placed in a container and transported into the chosen target container, controlled by an app. A load cell weighs simultaneously the quantity delivered. The process ends when the selected amount is reached.

This dosing machine was primarily designed for people with fine motor deficiencies due to physical disabilities or impairments (such as tremor, spasticity) to weigh ingredients as accurately as possible. The dosing machine is intended to offer the chance to cook or bake autonomously.

Morpheus – collission detection system

Results course “Embedded Systems
Single project 7/17

Morpheus is a wheelchair collision detection system that gives the user safe, collision-free movement.
The system includes several ultrasonic sensors as well as two microcontrollers and 3D printed mounts and boxes to detect potential dangerous objects and recognize reliably

Due to the not always possible all-round visibility and the lack of flexibility, wheelchair users in particular have to deal intensively with their environment in order to be able to minimize potential sources of danger right from the start.
