大家好我是浣熊老師，不知道各位有沒有玩過棒球的經驗呢? 棒球(Baseball)是臺灣的國球，屬於一種多人的球類運動，當打者用球棒將投手投出的球擊出後可以進行跑壘，若是成功回到本壘後便能得分。為了訓練打者的打擊技巧，球團會使用一種名為發球機(Pitching Machine)的機器，發球機能夠取代投手將棒球投出，避免投手長時間投球造成疲勞或損傷。 市售的發球機非常多種，浣熊老師今天要教大家做的是滾輪式發球機，滾輪式發球機具有上、下兩個能高速轉動的滾輪，當棒球經過兩個滾輪之間時，會被滾輪加速，並朝著打者的方向飛出，現在就讓浣熊老師一步步教大家如何製做滾輪式發球機吧！ ◆ 組裝步驟 第一步我們要來製做滾輪式發球機的主體，需要使用到5x15孔長方框、5孔超長條以及長結合鍵(圖一)，將它們依照圖示結合在一起(圖二)。 第二步要來加固滾輪式發球機的主體，主要使用到9孔長條以及長結合鍵(圖三)，將它們依照圖示安裝在主體上方 (圖四)。 第三步我們要來製做滾輪式發球機的上方滾輪，需要使用到OD33mm滑輪、OD36mm橡膠圈、60T齒輪以及100MMII軸(圖五)，將它們依照圖示安裝在滾輪

Hello everyone, I'm Samuel. This is my first time writing a blog, and I'm a bit nervous. I mainly want to share with you how to make a flower mechanism that can open and close. I will divide the steps into four parts, from the center axis to the petals

哈囉，大家好我是恩宇，這是我第一次寫blog，所以有些許的緊張。今天想跟大家分享，如何製作出可以開合的機械花。我將步驟分為四個：1.中心軸 2.花瓣 3.組裝上去大底盤 4.編寫程式讓他運轉，希望大家看完會喜歡！ 步驟一：將中心的轉軸組裝起來 以下是所需要的材料： 到這裡我們就已成功地把中心軸組裝完成囉！接著便是第二步是組裝花瓣開合的機關～ 步驟二：組裝花瓣齒輪機關 以下是需要事先準備的材料： 花瓣需要組裝六個所以請先準備好六份以下的材料 好了，接下來就要組裝在一起，並裝上大底盤囉～ 步驟三：組裝上大底盤 以下是需要準備的材料，可以事先把一個軸扣鍵以及兩個栓扣鍵裝在其中一個十五孔超長條上 到這邊，我們就已經完90%囉！最後，我們再寫入程式便可以讓花朵動起來！ 步驟四：編寫程式 以上是我寫完的程式，這裡要注意的是我所使用的工具(淺綠色)程式需要到擴展裡面新增，以下是這個程式的網址（https://github.com/gigotoys/gigo-block） 完整作動影片如下：

In Episode 9 of the Educational Time Machine, we introduced the definition of AI and its connection to Webduino blocks. In simple terms, AI (Artificial Intelligence) is a technology that aims to make computers think and execute strategies as much like humans as possible. However, have you ever wondered, since

In 1997, Deep Blue computer defeated the world chess champion, leading the world to contemplate the future direction of AI. Today, a new generation of AI, artificial intelligence, has arrived, and technological advancements have matured. Technologies such as smart furniture, autonomous driving, facial recognition are now widely applied in daily

Hey everyone, it's Teacher Raccoon! Our world is filled with countless inventions that serve practical purposes, like the telephone, electric light, and washing machine. These inventions greatly enhance our lives. However, today I'm going to teach you how to make something completely useless—an utterly pointless contraption known as a

In the video game "Besiege," players can create various whimsical medieval siege machines to combat castles or armies. Among them, the most impressive one is undoubtedly this rapid-firing catapult! This catapult uses two ramps to transport ammunition. Players only need to click the fire button. After the first ammunition is

I'm sure you've all heard the story of Newton being hit by an apple. Aside from learning that getting hit by an apple won't give you a concussion, it also taught us about the existence of gravity! Gravity is the force of attraction between objects with mass. It's what gives

The "Powerful Robotic Arm - Opening and Closing Mechanism" is a modification of the elastic lazy tongs. It was redesigned to achieve automation of the arm's movement. However, controlling elasticity with a motor proved difficult, as it was more suitable for rotational motion. Therefore, the modification was made to control

Iron Sky, Science DIY Explore Learning, Unlimited Creativity ♦ Scientific Principle: Using rubber bands as power to store elastic potential energy. After releasing the elastic energy, it impacts the rear of the airplane to launch it. ♦ Materials Needed: Step One, assemble one side of the launcher body and the board machine.

In many wilderness survival shows, challengers often create stone trap devices like this to secure a source of food. This seemingly simple stone trap can, when triggered by the bait, move one of the bamboo pieces, causing the heavy stone slab to instantly drop and capture the prey. It's well-suited

Sharing a simple crank-rocker mechanism (#1261+40X Motor+Battery Box=Handy) For unicyclists! Creating something from nothing is the most rewarding process~~~ Assembly Steps ▼ The most crucial lower body materials ▼ Assembly of the power unit ▼ Adding legs makes it look more vivid!!! (Remember that the connection points of the two

This is a simple crank rocker mechanism that originated from a video on Facebook. Let's create it using blocks! Assembly Steps: ▼ Materials for the imitation millstone section. ▼ Construct the rotating part imitating a millstone. ▼ Create the handle part (remember to use a bearing where rotation is needed!). ▼ Next, assemble the
