This article refers to the address: http:// This ball looks no different from ordinary tennis. Where is the secret? It turns out that he is a tennis ball that can roll himself! Want to know how to do it? Please see the DIY tutorial for the diced meat for everyone~ The idea comes from a group of strangely shaped spherical creatures in the film colony that James Rouvelle starred in in their living environment. The robot in the film puts the vibration motor in a styrofoam ball and then packs it into an irregular shape. The power system can make his balls swing from time to time. Today, let's make a thing that is more regular in motion and can roll in a fixed direction. Let's call it a scroll. Simply put, Rolling is basically a large vibrating robot with a large tennis jacket. Scroll in the direction of the drive. 1 Tools and materials â—One cutting pliers â—One blade â— A hacksaw (not shown) â—One sheet of paper â—‹ a large tennis ball â—‹ One two-section 7th battery compartment â—‹ two 7th battery â—‹One vibration motor* â—‹ a small brush â—‹Two buckles My vibration motor was removed from the back massager bought by the supermarket. 2 remove the handle â— Use a pair of needle-nosed pliers to cut off the handle of the brush. â— Then you need to handle the surface very flat. â— You can trim off excess plastic with needle-nosed pliers. â— If using a cutting pliers is too difficult, you can use a hacksaw to remove excess plastic together~ â— Processed as shown in the figure, our first step is done! 3 power switch â— Put the battery in the battery holder. â— Put a small piece of paper between the battery head and the battery card holder. This is to avoid the motor starting immediately when the circuit is connected in the fifth step. 4 fit binding â— Place the battery compartment on top of the plate brush and stack the motor on the battery compartment. Bind them with a buckle. This may take a little patience, but as long as you tighten the first buckle, it's easy. 5 Matchmaking â— Connect the black wire from the battery end to the black wire from the motor. â— Then connect the red line to the remaining line. As for the rest of the article, it will generally be a red line, but the motor I used this time is the blue line. The color does not matter, because the DC motor generally rotates regardless of the direction of the positive and negative terminals of the battery. â— If there is no wire on the motor, you need to solder the red and black wires to the power pins of the motor. 6 膛 膛 è‚š â— Pick up your blade and carefully cut a hole in the tennis ball that is enough to tuck the vibrating core. 7 transfer flowers â— Insert the vibrating robot into the tennis ball through the gap. â— Ah, yes~ Don't forget to unplug the blue patch between the battery and the battery compartment and let the motor power on. 8 starts to go away â— Now your robots should start to run away everywhere, secretly throw them into the tennis pile and let the innocent children in the unknown scream!
