1. 1. Prototyping of caterpillar Masanori Endo s1200176
2. 2. CATERPILLAR USING LEGO BLOCKS We want to create this product because rst time, we search robot object that uses Lego by using Internet.Then that robot car appeared.We thought that object is interesting so we select this product. Secondly, we thought this product can go ahead in any situation. Thirdly, the design of this product is interesting for us.We rst time to see the product that have many wheels.
3. 3. 1st Product Prototype using Tinkercad To create prototype with Tinkercad.The original photo was complex so we had to do deep observation. We would create caterpillar so we should to understand with assembly of caterpillar and system of caterpillar. After that we created the caterpillar step by step. Tinkered application can't express detail shape because we can only use box shape object, or cylinder shape object, or simple shape of object. So it's difcult to create prototype completely. But we contribute to express the original shape.
4. 4. 2nd Product Prototype using Autodesk 123D Design We created a prototype using the "123D Design" as 2nd prototyping. "123D Design" the same way as Tinckercad, can be used to create a prototype using 3D graphics. This software is designed small parts such as screws and gear from the beginning. So, it is possible to create a prototype close to the real thing than Tinckercad. In addition,Tinckercad is cloud-based. So, it can be used only in the browser. However, "123D Design" can be downloaded from the internet.Therefore, it can be used in local area. If we do a lot of editing in the download version of the "123D Design", it is sometimes unexpectedly quit. Image of this prototype is a caterpillar. It is not too large.This is connected to more than one tire in a small rectangular Lego block. So, it has joints.Thanks to the joint, it can be bent.This also has six motors to move the tire.Therefore, it can be entered into a small gap which can not be able to enter the human. If this caterpillar has a camera, when it entered the small gap, we can see the image of the place. This functionality is built into a robot for rescue well.
5. 5. 3rd Product Prototype using Autodesk 123D Make This software take in 123D Design model. And setting the option for create new model. Set to 10 the division number. Next, set the size of model. Finally,To show the developed parts.You can create this object in real life based on this developed parts.

26. 26. IDENTIFYTHREE IMPORTANT PROBLEMSYOU FACED DURINGTHE CONSTRUCTION OFTHE PRODUCT PROTOTYPES USING 123D DESIGN AND MAKE SOFTWARE. First problem is that download version "123D Design" force- quit frequently. If you use 123D Design in low specs PC, it will force-quit frequently. Second problem is that We can not be edited in their own design that is present from the beginning to the "123D Design". When we were applying the design was made with 123D Design in 123D Maker, it may not be reliably reect.

28. 28. CONCLUSION I felt to be very easy to do because it uses a Lego and initiative is seen.
