Creative DIY: Teach you to make "Robot Warrior"

I am programming an autonomous robot (autonomous, non-remote control) that recognizes and circumvents obstacles. She has a fully enclosed chassis and uses differential steering (original "tank steering", tank driving style), which uses two separately controlled motors to drive two drive wheels (one machine and one wheel)

The control signal comes from its own Arduino microcontroller (which can be easily replaced with a domestic microcontroller such as PIC, AVR, or Arm), and a steering gear for the Makey head. Makey's head is equipped with an ultrasonic probe, she will continue to shake her head left and right to get distance information in different directions, and store and process

1 Tools and materials

● (The list of tools and parts used has not been turned over here. After all, quite a few things are not realistic or necessary to buy the original version. - The domestic guys can also get the same method. Please refer to the original for interested children's shoes.)

2 making the fuselage

● The fuselage is made of two sheets of aluminum alloy sheet, and the processing methods involved are cutting, drilling and bending. You can process one piece at a time, or two pieces together to reduce the machine time of the processing equipment. Finished product see 2.5

● Note: Always wear protective glasses when cutting metal.

2.1 Cutting

● Use a band saw to cut the aluminum alloy sheet into the shape of the drawing. The edge of the cutting must be online.

● Tip: When cutting the inner corner, cut a rough curve first, then straight in from the two directions to get a right angle

2.2 Punch

● Use a punch and a small hammer to punch out the positioning hole at the 17th line with the crosshair on the drawing to prepare for the next drilling. In addition, it must be punched through the four corners of the rectangular hole on the figure.
