Soccer-playing robots

At the Baden-Württemberg Cooperative State University (DHBW) in Mannheim, the TIGERs develop small, soccer-playing robots that participate in the annual world championships of the RoboCup Federation. 

The robots are self-constructed from scratch and play entirely without human intervention. At the last world championships, the Mannheim TIGERs were honored with the "Excellence Award" for outstanding scientific contribution and overall performance.

In the fourth generation of robots, the motor was replaced with a more powerful variant: with 65 watts, the DF45L024048-A2 is ideal for this purpose, since the installation space is so limited that the smaller connection board of the A2 variant makes a big difference.

3-axis precision positioning system

At the South Westphalia University of Applied Sciences (FH Südwestfalen) in Iserlohn, a student developed a microdispenser with a 3-axis precision positioning system. This microdispenser uses an innovative method for dosing liquids that can dispense a very small quantity. 

Since the liquid is not dosed through a hollow needle, the dispenser is not dependent on the liquid's viscosity. This also eliminates frequently occurring cleaning processes. The C5-01 open-loop stepper motor controller from Nanotec was used in the microdispenser.

Inverted pendulum with programmable logic controller

At the Nuremberg Institute of Technology (Technische Hochschule Nürnberg), students have constructed an inverted pendulum with a programmable logic controller. The rigid pendulum rod can rotate freely at its attachment point. Through a controlled back and forth movement of the bearing point, the rod can be held in an upright state and interfering influences compensated for. Thus, the control task is the stabilization of the pendulum rod in its upright, unstable equilibrium position.

A linear axis is used to move the attachment point of the pendulum rod. The AS5918L4204-ENM24 stepper motor and the N5-1-1 motor controller from Nanotec are used as the drive system. 

The use of the closed-loop technology offers numerous advantages: 

  • Smoother motor operation
  • Faster acceleration
  • More precise positioning
  • Less warming of the motor

Autonomous Car

“Formula Student” is a worldwide design competition in which a group of university students, coming from every part of the world, present a formula-style race car prototype. This year, the Formula Student team “Sapienza Corse” (“La Sapienza” – University of Rome) tried to implement an ETC system in his car “Gajarda AWD”. An electronic throttle control allows an easier driveability, as the driver is not a professional one. Moreover it may provide significant improvement in terms of car efficiency.

The stepper motor ST2818L1404-A has been the key element of the entire system: it can provide with safety and precision the movement of the throttle valve, not affecting the rapidity of reaction nor the weight of the car. The motor also give us the necessary torque not to use a large gearing system.

Solar Boat

Técnico Solar Boat is a university project, made up of a group of students from the engineering courses of Instituto Superior Técnico. 

This season, they are building their second boat, the SR02. The SR02 will be 6m in length and 2m wide, and it will be lighter, faster and more efficient. To accomplish the set goals, the team is working on a hydrofoil system that lifts the boat out of the water to reduce drag. For this the students have an electronic control of the angle of attack of the underwater wings. This control is done with sensors and actuators, and these actuators come from Nanotec. 

The project group uses three stepper motors all controlled by N5-1-2 controllers, fitted with NOE2 encoders to know the exact position of the hydrofoils. These products have helped the team with detailed datasheets and the Plug and Drive Studio software in which they can try all the different modes of operation and easily set all the desired parameters.

Force Feedback Joystick

Students of the University of Kassel came up with the idea of building a Fieseler Storch flight simulator. In its current version, the simulator features a 180° screen that allows the pilot to get a realistic simulation of a propeller-driven aircraft from 1936. 

A haptic joystick will be integrated next, which will simulate the wind forces acting upon the rudder and flaps. To implement the feedback circuit, two stepper motors (PD4-C6018L4204) from Nanotec were used. The forces are transmitted via toothed belts at a ratio of 1:5.

A team of six students from the University of Augsburg designed and built a machine that can paint color patterns for the "Fritz-Felsenstein-Haus." 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 at 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.

During the summer semester 2017, students at Munich University built a household robot that can autonomously move around and vacuum. The robot features a gripper arm to pick up and transport objects. 

The students installed a high-torque stepper motor  ST5918L2008-B  size NEMA 23 and worm gear  GSGE60-25-1  from Nanotec in the robot's arm.

The student project "Manuscript Writer" is about a robot that is capable of mimicking handwriting. The robot's stylus was equipped with BLDC motors from Nanotec. The powerful BLDC motors size  DB59  were used as internal rotor motors.<u/>

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 HTBLA Rennweg in Vienna. This ski binding features automatic stepped adjusting depending on the uphill or downhill gradient. The binding adjusts correspondingly in automatic mode. 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  LSA201S06-A-TDBA-102  from Nanotec size NEMA 8 (20 mm)  are used. These facilitate the inclusion of space-saving linear axes.

The team at HTL Rennweg in Vienna developed a 2-axis robot in their robotics class, which is capable of cleaning and wiping blackboards (60 cm x 45 cm).

The students used the high-torque stepper motor  ST5918M3008-A  size NEMA 23 and two stepper motors  ST4209L1704-A  size NEMA 17 with the economy planetary gearbox  GPLE40 for the project. The  ST4209L1704-A  handles the movements in the X direction, while the second and third stepper motors are responsible for the Z direction.

“大学生方程式大赛”宣称的目标是在一年内设计和制造一辆赛车并使其越过欧洲赛道的终点线。自 2012 年以来,TUHH(汉堡-哈尔堡技术大学)的电子技术团队每年都成功参加这场电动赛车的角逐。这个团队由来自各个 TUHH 学位课程的近 60 名学生组成。2017 年,在霍根海姆赛道举办的每年一度的“德国大学生方程式大赛”中,他们在电动汽车参与者中获得第 9 名的佳绩。

2017 年新推出的无人驾驶类别要求将现有车辆改装成全自动驾驶车辆。为此,学生们使用 Nanotec 的 DB59S024035 直流无刷电机来旋转转向轴,从而自动操控汽车。它取代了通常由驾驶员使用双手来转动方向盘的操作。

电子点火团队在比赛结束后非常高兴,因为他们的自动驾驶赛车在“自主设计奖”中取得世界排名第三的出色成绩。

经过 13 个月的努力,由比利时鲁汶大学的 21 名学生组成的团队设计了一款新的太阳能汽车 Punch 2,借此他们参加了在 10 月 8 日举办的澳大利亚普利司通世界太阳能挑战赛。为了参加此次比赛,他们从达尔文飞到阿德莱德,直穿澳大利亚内陆,行程长达 3,000 公里。 

今年的这款太阳能汽车有很多新奇亮点。Punch 2 配备了一个独特的机械四轮转向系统,它由机械分离的前后轮转向器组成。这意味着前轮会在方向盘发生第一个 90° 位移时旋转。当驾驶员继续转动方向盘时,则会继续启动后轮转向。转向动作通过钢缆传递到四个车轮上。

为了测试新系统,这个团队决定构建一个转向系统的副本。Nanotec 的直流无刷电机与变速箱配合使用并与方向盘连接,以模拟比赛中的转向运动。转向力使用强力弹簧来模拟,它需要变速箱提供所需的转矩。

慕尼黑应用科技大学机械电子和精密工程专业的学生为吉他拾音器开发了一台自动绕线机,并在 2016 年夏季学期的“机电一体化”研讨会中亮相。

他们开发了一种特殊的弹簧系统,使得漆包线在拾音器线轴上缠绕时不会卡住。为了驱动拾音器的旋转,他们采用了步进电机 ST5918。在 SMCI35 控制器的帮助下,可以在绕线数增加时让驱动电机的速度逐渐增加到某个阈值。然后电机以恒定速度旋转,直到绕线完成。

此外,通过外部线性执行器 LS20,使得线材平行于拾音器旋转轴在线轴的整个宽度上连续馈送。

2016 年 5 月 14 日至 5 月 15 日,Ecorace 挑战赛第三期在比利时布鲁日举行。七个团队使用他们的比例模型参与比赛,争夺最具创新性船舶、最佳全能载货船、最佳全能非载货船和最佳商业计划奖项。

最具创新性船舶和最佳全能载货船的奖项都被鲁汶大学的“Galena”获得,这是一艘货船模型,用来运载一吨货物并在内陆航道航行。将来,Galena 应该能够完全自主航行。Nanotec 的  PD4-N5918L4204  被连接到 Nanotec 的变速箱  GPLE60-2S-16,作为这艘船的转向装置。  

我们祝贺 Dominic Libanio、Christian Schorr 和 Pascal Lindemann 荣获 “Jugend Forscht” 地区竞赛冠军以及莱茵兰-普法尔茨州创意竞赛第二名。这个得到 Nanotec 电机支持的项目旨在开发一款手部治疗仪器。

由于成本和时间因素导致运动疗法无论是在规定上还是在执行上,都无法到达所需的限度,所以手部在接受手术和后续治疗后通常无法达到最佳治疗效果。由此可能造成手指关节的基本运动受限,运动机能敏感性失常。这款手部治疗仪器将为医生和理疗医师提供支持。该仪器为每根手指提供可独立调节的机械机构,这些机械机构由 Nanotec 线性电机驱动。 

在柏林经济学院,应用工业电子专业的学生受托开发一款机器人,要求该机器人能够根据定制软件建造任意高度和形状的墙壁。 一个由机载 ATmega32 控制的虚拟自动无线运载工具在六个月之内建成。 这一运载工具由两个机载 Nanotec 步进电机驱动,每个电机带动一个轴装外铝轮毂,实现精准位置控制。前后两个支撑架在增加该运载工具重量的同时,还能在运载工具行驶过程中来回滑动,从而确保稳定性。前部线性执行器推动一个手臂沿线性导轨上下移动。配备电磁铁的手臂可以提放木块,而木块则用金属板固定并放在预设位置。该运载工具由 12 伏锂聚合物电池供电。借助直观的用户界面,用户可以操控运载工具在基站和建筑工地之间行驶,最终建成高度不同的墙壁。

从 2009 年开始,德国盖尔森基兴市的威斯特伐利亚大学机械工程学院每年都会举行一次应用科学年度竞赛。每个参赛的学生团队要开发出一台机器来完成特定任务。今年,他们接受的挑战是设计和制造用于冠形瓶塞的自动开瓶器,并对其进行编程。在开瓶之后,开瓶器还要将预定数量的饮料自动倒入玻璃杯中。2015 年度竞赛的获胜者是一个四人设计团队,他们选择了 Nanotec 的线性执行器 LS4118S1404-T6x2-75 来执行开瓶动作,而该线性执行器的更快速度和更高可靠性成为了他们获胜的决定性因素! 

慕尼黑应用科技大学的机电一体化及精密工程项目模块旨在从项目概念或现有项目来设计完整的产品,其中包括演示和论证过程。2015 年夏季学期的学生设计了一款蠕动泵,每分钟能够恒定输出一升流体。这涉及到编写必要软件、建造泵并把它投入使用 – 而且全部预算要控制在 100 欧元以下。因此,该团队使用慕尼黑应用科技大学的 3D 打印机来生产设备中的大部分部件。蠕动泵使用 Arduino Micro 进行控制,由其负责与 PC 通信、启动电机和评估传感器。电路板在该大学的电子实验室中完成焊接并放入 μC、电源系统的部件和电机驱动器。速度通过一个开孔圆盘监控并使用软件进行评估。为了让用户能够操作泵,该小组使用 C-Sharp 编写了一个前端。Nanotec 步进电机充当了蠕动泵的软件和设计部件之间的接口。 

在吉森大学的应用戏剧研究学会,有一个学生项目是重建德国民族传统游戏 “肯塔基赛马”  。在这个技巧游戏中,玩家要能够熟练操控比赛球来促使其机械马前往终点。与原型不同的是,新版本中的玩家不直接与游戏过程进行互动。相反,参赛者都坐在另外一个由摄像头监控的房间里面。玩家的热情越高,越能激励他的马快速跑向终点。例如,通过叫嚷或拍手,叫的越响、拍的越快,马跑的越快。这些马由 Nanotec 提供的步进电机 PD4-N6018L4204 驱动。这些电机由相同的软件(光线和声音)控制,实现了机械元件和视听媒体的完美结合。 

Nanotec Electronic  是 奥格斯堡应用科技大学开发的  MALOMAT  项目的支持者之一。 这个项目的目的是 开发出一台设备,使残疾儿童能够自己在画布上涂鸦。 

位于科尼格斯不伦的弗里茨-费尔森施泰因豪斯是一所为身体残疾和智力障碍儿童开设的学校。在这里,画画是课堂上的重要内容。但这通常需要大量复杂的过程才能实现,因为孩子们无法自己在普通画布上画画。他们首先会选择一种颜色,并告诉他们的老师要绘制在画布的哪个部分。 老师使用画棒,从画布的选定位置向下画出线条。   

而借助于 MALOMAT 项目,这些儿童可以自己在画布上画画。经过一些简短的准备工作之后,可以画出三种不同颜色的线条。  这两个程序可以完全由一个或多个孩子控制,从而也可以实现不同的难度。Nanotec 通过提供齿轮电机和控制器来支持该项目。 

2014/2015 冬季学期,卡尔斯鲁厄大学机电一体化专业的学生在项目研究中开发了一款曲棍球机器人。该机器人将取代一名玩家,与另一名玩家对战,它能完全自主行动,并根据游戏本身的情况作出决定。球的位置和速度由传感器系统获取,并由电子评估系统进行处理,随后数据被发送到机械控制推进器,使它可以移动到一个特定的位置将球击回。Nanotec 的步进电机用来移动与推进器相连的连接架。ST5918L4508 在该应用中提供恰当的转矩并由 SMCI35 控制器驱动。

这个装置并不常见: 用于产生风电的风筝。 Nanotec Electronic GmbH & Co. KG 通过六个 SMCI36 和 SMCI35 步进电机控制器为该项目提供支持。  

它由位于海登海姆的巴登-符腾堡合作州立大学的八名有抱负的工业工程师建造。通过他们的发电厂,这些学生在 2011 年度的欧洲卫星导航大赛巴登-符腾堡挑战赛中(也称为“伽利略创新大赛”)上获胜,荣膺欧洲最佳团队。
