This is a moving robot works to calculate ambient objects and gives an alarm when it exceeds a certain limit, measuring the room temperature then gives report, Also can controlled by the computer, or smartphone to do some cool staff.
Step 1: Robot Head
First step is always (The IDEA):
I used this paper craft model form paper-replica: Download the paper model from here
Then I saw that, when I place the electronics parts inside that model and Make it Alive, I think it will be very cool Idea.
* I start folding the paper model as usual then I fix the Ultrasonic sensor inside the robot head as a beginning to be Instead of the robot's eyes.
Step 2: Testing the Sensors
Testing the sensors after placing it inside the head.
I used an Arduino Uno and an ultrasonic sensor to make the robot measure the distance in front of it.
For example, if the object is 10 cm away from the sensor, and the speed of the sound is 340 m/s or 0.034 cm/µs the sound wave will need to travel about 294 u seconds. But what you will get from the Echo pin will be double that number because the sound wave needs to travel forward and bounce backward. So in order to get the distance in cm we need to multiply the received travel time value from the echo pin by 0.034 and divide it by 2, In this case the robot will sound the Alarm.
Here is full tutorial how to use ultrasonic sensors: https://www.arduino.cc/en/Tutorial/Ping
Step 3: Body Mechanism
To make the robot more realistic, I put three micro servo motors 9g inside the body to control the movement of the head and arms, those servos are controlling via same Arduino microcontroller.
Have a look what is servo motor and what it’s able to do: https://www.arduino.cc/en/Reference/Servo
Step 4: Robot Arms
The Robot still miss two arms :) So I installed the structure of the Arm paper model as shown then I placed the servo gear inside it, so as to easily control them and see it moves.
Step 5: Circuit
As shown the robot has cardboard base, so I used it to fix the circuit and it was not so easy.
Actually the Circuit is very simple and its contents of:
1 Arduino Uno R3
1 Red LED
3 Micro Servo
1 Piezo
1 Ultrasonic Distance Sensor
1 150 ohm Resistor
1 Green LED
1 Slide switch
1 Temperature Sensor [TMP36]
