This tutorial will give you an idea as to how you can connect and control servo motors with ARIES v2.0 board. Micro Servo Motor SG90<\/em><\/strong> is used here. You can see how the servo motor is rotated when the sample program vega-sdk\/examples\/pwm\/servo_motor_demo is run on ARIES v2.0 board.<\/p>\n\n\n\n

Servo motors<\/h2>\n\n\n\n

A servo motor is a device that contains an encoder which converts the mechanical motion (turns of the shaft) into digital pulses<\/strong> interpreted by a motion controller<\/strong>. It also contains a driver; and in conjunction, they make up a circuit that governs the position, torque and speed.<\/p>\n\n\n\n

Their main specifications are torque and speed.<\/p>\n\n\n\n

Servo motors are considered to be fundamental in the design and manufacturing of robots<\/strong>. These are systems that require precise and controlled mechanical positioning. We can see them in fields such as industrial automation<\/strong><\/a> or the growing robotic surgery<\/strong> field.<\/p>\n\n\n

Circuit Diagram<\/h2>\n\n\n\n

The Servo Motor SG90<\/em><\/strong> has three pins: VCC, PWM Signal, and GND. Connect VCC and GND of the servo motor to +3.3V and GND respectively of ARIES v2.0 board. Then connect the Signal Pin<\/strong> of the servo motor to the PWM pin PWM0<\/strong> of the ARIES v2.0 Board.<\/p>\n\n\n\n

Now, for powering up and burning the code into the ARIES v2.0 Board, we have to connect a micro USB type B<\/strong> (common data cable, used for mobile charging and data transfer) in the UART0<\/strong> port of the ARIES v2 .0 Board, to a Laptop\/Desktop\/pc with preinstalled VEGA SDK and Toolchain.<\/p>\n\n\n\n

Procedure<\/strong><\/h2>\n\n\n\n

After setting up the toolchain and SDK path environments, build the example program for servo motors by:<\/p>\n\n\n\n

cd vega-sdk\/examples\/pwm\/servo_motor_demo<\/code><\/pre>\n\n\n\n
clean command to clean the executable :<\/p>\n\n\n\n
make clean<\/strong><\/code><\/pre>\n\n\n\n
then use make command to build it.<\/p>\n\n\n\n
make<\/strong><\/code><\/pre>\n\n\n\n
Now, we can transfer the built program to the board, before transfer please ensure that you have connected the board UART0 connector to the PC.<\/p>\n\n\n\n
Open a new terminal and execute the following command.<\/p>\n\n\n\n
minicom aries<\/strong><\/code><\/pre>\n\n\n\n
Now you can see the minicom terminal opened and the board UART terminal is ready.<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
Use CTRL+A<\/strong> and then press S <\/strong>to enter file sending menu and select xmodem <\/strong>by pressing Enter.<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
In the next window, with the space bar<\/strong> select the servo_motor_demo.bin <\/strong>file to be transferred, by pressing Enter<\/strong>, the transfer process starts.<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
Wait until the process is completed. The screen should display how much data has been transferred.<\/p>\n\n\n\n
After completing transfer the Program will start to execute.<\/p>\n\n\n\n
The Servo Motor starts and rotate 0\u00b0 to 180\u00b0 and again in reverse direction i.e.180\u00b0 to 0\u00b0.<\/p>\n\n\n\n
