This article will introduce a very interesting topic in HowStuffWorks: how to make a simple mechanical arm. This topic will provide you with detailed steps and a list of materials needed to make a robot arm.
Bill of materials:
A board
a piece of wood
Some metal pipes
-Some screws and nuts
Some wires
-A motor
-A battery pack
-A switch
-Some wire strippers and pliers
-Some glue and tape
Step 1: lay the foundation for the mechanical arm.
First, you need to lay a solid foundation for the robotic arm. Cut the board into rectangles, drill holes in it, and install other parts of the mechanical arm. Then, cut the wood block into a small square, which is used as the palm of the mechanical arm.
Step 2: Make the joints of the robot arm.
Next, you need to make the joints of the robot arm. The metal pipe is cut into two pipes with equal length, and several holes are drilled in the pipes to install other parts of the mechanical arm. Then, fix the screws and nuts on the pipeline so that they can rotate.
Step 3: Connect the joints of the robot arm.
Connect two metal pipes into an L shape and fix them with screws and nuts. Then, connect the motor to the metal pipe, and connect the wires to the battery pack and the switch.
Step 4: Make the fingers of the robot arm.
Finally, you need to make the fingers of the robot arm. Cut the metal tube into three equal-length tubes, drill several holes in them, and install other parts of the mechanical arm. Then, stick them together and fix them on the palm of the robot arm.
conclusion
Through the detailed steps of HowStuffWorks website, you can easily make a simple mechanical arm, which is a very interesting project. In addition, the website also provides many other interesting scientific and technological knowledge, which can help you better understand the world. If you are interested in technology, then HowStuffWorks is a website worth exploring.
