The game championship at the end of the global Great Great Marrata Harbin Institute of Works has been obtained by a team called SZDIY. They built a drawing robot in the 48-hour game, and successfully painted a fish on the stage and wrote three words of "Harbin Institute of Technology". It seems to be cool.
But that is the work of others. Have you ever thought that you also make a such robot trolley? Hard Bang Xiaobian has found a similar project tutorial on the instructable, let us come to see how to see it!
Step 1: Component Preparation
Drawing robots involve many different motion control units, the following is the list of components you need:
Electronic components:
Adafrouit Pro Trinket 3V (you can also use Arduino)
2 Geared 5V Stepper Motors
ULN2803 Darlington drive
Breadboard
16 mother ports jumping
Micro servo motor
Mother pin
2 2 x aa battery packs
USB cable
4 AA batteries
Open source development board recommended:
P1601-DK02 development boards are based on Parallella-16 boards with full computer profile to ultrasonic devices, supercomputers, large data analysis development boards.
A20-Olinuxino-Micro development board A compact android / Linux for the application code developed by the A20 microcontroller through the application code of the Cortex-A7 dual-core processor of ARM.
ARDUINO UNO R3 development board A processor core is an open source hardware development board for Atmega328 easy-to-use open source controller.
Structure:
2 7/8 "ID X 3 / 16'o type circle
5/8 "casters
10 M3 x8 mm cut screws
4 M3 × 6 flat head screws
12 M3 nuts
3D printing component:
Ball bearing casters (files)
Chassis (file)
2 wheels (files)
2 Steps Motor Bracket (File)
Servo motor bracket (file)
Set of circles (files)
Step 2: Configure the development of necronomance and write firmware

Write the firmware Tirl_trinket_test.ino into the Trinket board, which is also worth mentioning that the firmware and Arduino are also compatible.
Step 3: Hardware assembly
Although theoretically, as long as each component is connected in place, it is necessary to ensure that the things written by the plot robot is the same, or should be paid to the installation location of each component.
Install the battery case
Assemble wheel
Install stepping motor
Install the casters

ARDUINO UNO R3 development board A processor core is an open source hardware development board for Atmega328 easy-to-use open source controller.
Next, you should install electronic control components. There are many lines to pick, don't look good!
First, install the microcontroller, Dalinton to the east and switches to the breadboard. Connect according to the figure, install the battery and open the switch after connecting, you can see the LED light on the board begins to illuminate.
Install the wiring head and connect the motor.
Install the brush, the position adjustment of the pen can be completed manually, or adjust it on the software:
INT PEN_DOWN = 170; // Angle of Servo When Pen Is Down
INT PEN_UP = 80; // Angle of Servo When Pen Is Up
Step 4: Completion
After installation, you can test it. The above test firmware TIRL_TRINKET_TEST.INO can only draw a square, but this is enough to detect the balance of the robot.

Start the performance after the test is complete! Draw a rose:
Other platforms
In fact, using other development platforms (Arduino or Raspberry Piva) can also create similar drawing cars that create different versions based on different platforms.
