For many years now, Nanotec Electronic GmbH & Co. KG has been sponsooring research projects in Universities, Colleges and Academies with products and expertise. The funding of a scientific project is carried out under the following conditions:
it is thematically innovative, it is based on methods of scientific work and its results may have a positive impact on society.
Since the summer of 2011, the Deutschlandstipendium provides monthly financial support of €300 to high-achieving and committed students. Modeled after the principle of public-private partnership, businesses, foundations or private individuals sponsor young talent with a pledge of €150 per month. The Federal Government matches this amount with another €150. But there is even more: Many universities and private sponsors also support Germany Scholarship holders through concurrent mentoring programs, networking events and internships.
In our view, talented scientists are the key to Germany's economic future. This has to be supported. Therefore Nanotec Electronic is one of the sponsors of Deutschlandstipendium.

A team of six students from the University of Augsburg designed and built a machine for the "Fritz-Felsenstein-Haus" that can paint color patterns. The facility is home to people with various disabilities.
The "Paint Catapult" project uses the ST8918M6708-B high-torque stepper motor from Nanotec to drive a rotary plate. The students installed a sheet of paper on this plate, onto which paint is dripped using a linear carriage and pump elements. The rotational force guides the drops of paint outward, which results in unique patterns, depending on the speed and application position. The speed is set on the touchscreen display after starting up. The three buttons on the screen serve to select the color, spindle position, and apply the paint, making the device easy to operate.

The WARR Hyperloop team from the Technical University of Munich built a floating pod. Four linear actuators lift the pod, so that it can start the hovering drives. This is done using four L3518S1204-T6X1-A25 linear actuators size NEMA 14 from Nanotec.
Once the drives are rotating, the "Nanotec legs" are automatically retracted and the pod floats magnetically. Payloads weighing up to 50 kg can be transported.

The student project "Manuscript Writer" is about a robot that is capable of copying handwriting. The robot's stylus was equipped with BLDC motors of the DB59 series from Nanotec.
For the robot to be able to retract from any given position, the two large motors (axes 1 and 2) require a minimum torque of 21 Ncm, and the small motor (axis 3) 4.5 Ncm: this happens as soon as the robot's arm is fully extended at a 90° angle.

The "Easy Going" touring ski binding is a project by students from the university HTBLA Rennweg in Vienna. This ski binding features automatic stepped adjustment depending on the uphill or downhill gradient. The binding adjusts automatically. If the ski tourer selects manual mode, the level can be selected at the push of a button.
Each binding features a motor, battery, microchip, and a wireless module. Two linear actuators of the LSA201S06-A-TDBA-102 series from Nanotec (size NEMA 8 20 mm) are used. These facilitate the use of space-saving linear axes.

The declared goal of the "Formula Students" is to design and build a race car within a year and drive it over the finish lines of Europe's racetracks. The e-gnition team of the TUHH (Technical University of Hamburg-Harburg) has successfully participated in this contest with its electrical race car every year since 2012. The team consists of almost 60 students from all TUHH degree programs. In 2017, they ranked 9th amongst participants with electric vehicles at the "Formula Student Germany" which takes place annually at the Hockenheimring race track.
New in 2017 was the driverless category, in which an existing vehicle is converted to a fully autonomous vehicle. In order to do this, the students used Nanotec's DB59S024035 brushless DC motor to rotate the steering shaft and thus steer the car autonomously. It replaces the hands of the driver who would normally turn the steering wheel.
The e-ignition team was delighted after the race, as their autonomously driving race car came in third in the world ranking of the "Autonomous Design Award".

For 13 months, a team of 21 students from the University of Leuven in Belgium worked on the Punch 2, a new solar car with which they started in the Bridgestone World Solar Challenge in Australia on October 8. The race lead straight through the Australian Outback, from Darwin to Adelaide, over a distance of 3,000 km.
This year a lot of novelties have been put in the solar car. Among other features, the Punch 2 is equipped with a unique mechanical four-wheel steering system which consists of a mechanically decoupled front and rear wheel steering. This means that the front wheels rotate with the first 90° displacement of the steering wheel. When the driver continues to turn the steering wheel, the rear wheel steering is activated additionally. The steering motion is transferred to the four wheels using steel cables.
In order to test the new system, the team decided to build a copy of the steering system. A brushless DC motor from Nanotec was used in combination with a gearbox and linked to the steering wheel to simulate the steering movements during the race. The steering forces were simulated by using strong springs which required a gearbox to provide the required torque.

Students majoring in Mechatronics and Precision Engineering at the University of Applied Sciences Munich developed an automated winding machine for guitar pickups as part of the "mechatronic integration" seminar in the summer semester 2016.
A special spring system was developed so that the enameled copper wire did not snap when it was wound onto the spool. For driving the pickup, the stepper motor ST5918 was used. With the help of a SMCI35 controller, it was possible to actuate the motor in such a way that there is a ramped increase in speed up to a threshold value when the number of windings increases. Then it rotates at a constant speed until the process is stopped.
Furthermore, by using the external linear actuator LS20, the wire is fed parallel to the rotational axis of the pickup across the whole width of the spool continuously.
From May 14 to May 15, 2016, the third edition of the Ecorace-Challenge took place in Bruges, Belgium. Seven teams competed with their scale models to win the award for the most innovative vessel, the best all-round cargo vessel, the best all-round no-cargo vessel and the the best business plan.
The awards for the most innovative vessel and the best all-around cargo boat went to the University KU Leuven for "Galena", a model of a cargo vessel designed to carry one ton of goods and sail inland waterways. In the future Galena is supposed to sail completely autonomous. The steering of the vessel is powered by Nanotec's PD4-N5918L4204 connected to Nanotec's gearbox GPLE60-2S-16.
We congratulate Dominic Libanio, Christian Schorr and Pascal Lindemann on winning first place in the regional "Jugend Forscht" competition and on coming in second in the Ideenwettbewerb Rheinland-Pfalz ("Ideas Competition"). The project, which Nanotec supported with motors, dealt with the development of a hand therapy device.
Often, the results achieved by hand surgery and follow-up therapy are not satisfactory because physical therapy is neither prescribed nor performed to the extent necessary for reasons of cost and time. The consequences range from elementary restrictions in movement to significant disruptions in the fine motor skills. The therapy device for the hands shown here is intended to support physicians and physiotherapists. Each finger receives an individually fitted mechanism that is driven by a Nanotec linear motor.
At a Berlin school, the students of Applied Industrial Electronics were asked to develop a robot that builds a wall of any height and shape on the basis of custom software. Controlled by an on-board ATmega32, a virtually autonomous wireless vehicle was then constructed within six months. This vehicle is powered by two on-board Nanotec stepper motors, each driving a shaft-mounted, exterior aluminum wheel, thus providing precise position control. Stability is ensured by two supports on the ground at the front and back that slide when the vehicle is in motion and bear part of the vehicle's weight. A linear actuator on the front drives an arm up and down a linear guide. Equipped with an electromagnet, the arm lifts and places the wooden blocks, which are fitted with a metal plate, in a predetermined position. The vehicle's power supply is ensured by means of a 12V lithium-polymer battery. With the help of an intuitive user interface the user controls the vehicle as it travels between the base station and building site to erect a wall of variable height.

Since 2009, the institute for Mechanical Engineering at the Westphalian University of Applied Sciences in Gelsenkirchen has held an annual competition where teams of students develop a machine that has to fulfill a specific task. This year the challenge was to construct, manufacture and program an automated bottle opener for crown corks. After opening the bottle, a defined amount of the drink should be poured automatically into a glass. The winner of the 2015 competition is a bottle opener where the four-member construction team had selected the linear actuator LS4118S1404-T6x2-75 from Nanotec for opening the bottles – the decisive factors were speed and reliability.
The purpose of the Mechatronics and Precision Engineering project module at the University of Applied Sciences Munich is to create a finished product, including presentation and demonstration, from a project idea or an existing project. The students of the 2015 summer semester embarked on designing a peristaltic pump with a delivery rate of one liter per minute. This involved writing the necessary software, building the pump and taking it into service – all with a budget of under 100 euros. The team therefore used the 3D printer of the University of Applied Sciences Munich to produce most parts of the construction. The peristaltic pump was controlled using an Arduino Micro which was responsible for communication with the PC, actuation of the motor and evaluation of the sensors. The board was soldered together in the electronics lab of the university and accommodates the µC, parts of the power supply system, and the motor driver. The speed is monitored by means of a perforated disk and evaluated using software. To allow the user to operate the pump, the group wrote a front end using C-Sharp. A Nanotec stepper motor provides the central interface between the software and the design part of the peristaltic pump.
At the Institute for Applied Theater Studies at the Justus Liebig University Giessen, a student project had the task of reconstructing the Kentucky Derby – a country fair game booth. In this game of skill, players adroitly maneuver game balls to urge their mechanical horses toward the finish line. Unlike the archetype, however, this new version has no direct interaction between the players and the course of the game. Instead, the participants are seated in another room where the game supervisor observes them on a camera. The more enthusiasm the players demonstrate as they encourage their horses toward the finish line – by shouting or clapping, for example – the faster the game supervisor moves the horses forward. The horses are powered by Nanotec stepper motors of type PD4-N6018L4204. These are controlled by the same software as the light and sound installations – a perfect combination of mechanical elements and audio-visual media.
Nanotec Electronic was one of the supporters of the MALOMAT project, which was developed by students at the University of Applied Sciences Augsburg, to provide severely handicapped children a possibility to paint a canvas on their own.
The Fritz-Felsensteinhaus in Köngisbrunn is a school for physically and mentally disabled children. Painting takes an important part in their education. This is often only possible with a great deal of effort because the children are unable to paint on regular canvasses on their own. They choose a color and indicate to their tutors which part of the canvass is to be painted. The teachers use paint tubes and allow the paint to run down the canvass from the selected point.
The MALOMAT allows the pupils to do the painting on their own. After some brief preparatory work, it is possible to paint lines in three different colors. The two programs can be controlled fully by one or more children, whereby different levels of difficulty are also possible. Nanotec supported the project by providing a gear motor and a controller.
In the winter semester 2014/2015, mechatronics students at the Karlsruhe University of Applied Sciences developed a table hockey robot as part of a project study. The robot is supposed to replace a player and play against a human opponent, acting completely autonomously and making decisions about the play situation by itself. Both the puck position and its speed are registered by a sensor system and processed by evaluation electronics. The data is then sent to the mechanically-controlled pusher, so that it can move to a particular position and push the puck back. Nanotec stepper motors are used to move the carriages to which the pusher is fastened. The ST5918L4508 provides the right torque for this application and is operated here by the SMCI35 controller.
