Technology is erratic. We never know what could be the next big thing. Nowadays, IoT (the internet of things) has taken over the market. Every technology created nowadays is somehow related to IoT. You should manage to connect the IoT technology with a robust area of hospitality. Catering customers' needs during peak hours at any restaurant or cafe could get overwhelmed with hectic tasks such as taking orders, fetching water, and ordering meals. We created a raw model to accommodate the limitations of the human mind. The technology-based IoT (Internet of things) can come in handy during hectic sessions. A Robot waiter is built from scratch using materials like Arduino (2), Gear DC motor (2), L298N motor driver (1), Ultrasonic sensor (2), IR sensor (2), Servo motor (4) HC-05 Bluetooth module. Desired orders are sent on a wireless network through the menu bar to the kitchen. Then, the robots transfer the food from the kitchen to the customers. The floor will be all white, while there will be a strip of black line to connect every sitting and the kitchen. For instance, if table number three is to be served, we click the number three in the app, which renders an obstacle in table 3. The motor barricades the robot, and the ultrasonic sensors sense it, and it stops. If anyone picks the plate, the ultrasonic sensor senses it, the blockage is removed, and the robot paces in the designated path. People visited the place more often to experience such stimuli. Using the robots attracted more customers and made the work very quick.

臨床手術中常有骨釘植入位置偏差之情形，且目前並無研究針對骨釘植入位置對椎體力學反應之探討，故本研究使用CAD軟體Solidworks建立11個不同骨釘植入位置的人體第三節腰椎模型，利用有限元素分析軟體ANSYS進行力學模擬分析，計算不同骨釘植入位置於不同負載條件以及有無骨整合情況下，腰椎椎體的應力情形與整體結構之穩定度。研究結果顯示，在不考慮傷及神經或是骨釘穿出骨頭的情況下，當椎體與骨釘若受前彎(flexion)、後仰(extension)、側彎(lateral bending)、旋轉(rotation)及無軸向負載(pure bending)時，骨釘螺帽中點至棘突中軸的垂直投影距離越小，椎體位移亦越小，結構越穩定；且不論有無骨整合都呈現相似走勢。骨科醫師表示仍會選擇打在目前最普遍的植入位置最為保險；但依照本研究結果，當臨床手術醫師面臨植入常規位置困難度較高時，骨釘植入位置若稍偏外側穩定度並不會有顯著差異，且可避免傷及中樞神經系統。

高職機械群科在學習的過程中常常接觸到射出成形相關領域，我們想自主設計開發微形射出成形機，並和工業界生產的機台以液壓為射出機構不同。所以本專題以3D列印機的運動控制及材料加熱系統為基礎，利用變導程螺桿的加壓射出機構及螺桿導軌鎖閉模機構來完成射出成形所需的各個機械動作。變導程螺桿做出材料的輸送及射出動作，加壓後可將空氣排出，進而取代了原本注塞式和一般螺桿式的加壓射出；再利用公模、母模、頂射板和母模固定板所形成的射出模系統，進行自動化。由於機台微小化，操作方式和現行3D列印機操作方式類似，所以可作為教學之教具使用，亦可由同學自行設計模具進行射出成形操作。也能針對不同的材料做為射出的成品。

臺灣已進入高齡社會，步態復健對於亞健康及慢性病族群極為重要，以帕金森氏症患者為例，他們常行走困難且容易跌倒。提升跨步品質的視覺提示是非常有效的協助方式，但臨床多仰賴治療師在地上貼膠帶或擺物件，調整不易且只受限於特定場所，因此居家自行照顧困難。先前已有研究開發出輕便可攜的裝置，能調整視覺提示，但每位使用者對不同提示模式的反應不一。本研究提出創新方法解決治療師手動調整的問題。以低成本周邊所建置的系統已能即時無線的變換不同提示模式、調控其參數，和自動計算各步態參數。其使用MG90s伺服機調整投射角度、霍爾式旋轉角度計裝在輪子上測量位移、Wi-Fi無線接收及操控參數。已經完成自動化探索使用者能力，並作最佳化的視覺提示設定。讓使用者不必出門，居家使用時，皆有最佳的視覺提示設定，得以更短的時程達到更好的復健效果。

This paper represents IOT Based Automatic Water Temperature Adjustor. IoT (Internet of Things) refers to the network of physical objects that are embedded with sensors, software, and other technologies for the purpose of connecting and exchanging data with other devices and systems over the internet. This system is for adjusting water temperature according to the possible surroundings such as home temperature, atmosphere temperature, etc. To solve problems like high water temperature while using, time-consuming waiting for water to heat and cool, high power consumption, and not satisfying water temperature this system offers the feature for automatically adjusting the temperature. Arduino, DHT11 (Temperature-Humidity Sensor), Bread Board, DS18B20 (Water Temperature Sensor), Jumper Wires, Resistor, I2C OLED, Water Heating Coil, Relay and LED are used for operating this system. The application of this system is very vast as it can be implemented in power plants, hospitals, mountain regions, local homes, and lodges. This system is time-saving, cost-efficient, easy to implement, provide automatic features, less power consumption, safety, and many more. Compared to other water geyser systems it has the feature of automatically detecting the environmental temperature and adjusting the temperature of the water accordingly. This system is still in its developing phase.

隨著行動裝置與人工智慧的普及，物聯網的實現已指日可待，由於物聯網中感知器數量數以億萬計，因而整個系統對自供電的依賴也越來越深。雖然傳統電化學電池可以滿足大部分物聯網在目前階段的電力的需求，但一旦大量佈建後，更換那些電池便成為一件棘手的事情。因此，可以採集環境光能的太陽能電池是優先的選項，其中以染料敏化電池不受環境光強度及溫度的影響，且能以用網印方式製作在廉價的基板上，來提高太陽光照射的面積而不受基板大小的限制。在電能儲存方面，採用固態電化學電容，除了提高電荷密度外，也不受太陽能電池與電化學電池因電壓不匹配而造成無法充電的現象。並將兩種個別裝置整合在同一基板上，除了縮小尺寸外，還有降低系統阻抗的功能。本次研究希望能結合染料敏化太陽電池”有光即發電”的特性，最後達成能量採集及能量儲存於單一裝置的目標。
