OpenELAB 4WD Mechanical Arm Robot Smart Car for Arduino


Product Link

KS0523 4WD Mechanical Robot Arm Smart Car

Description

As science and technology develops by leaps and bounces, human society moves towards an era of intelligence and automation as well.

Our hands are weak and unresistant to ultra-cold and high temperature environment. In this regard, mechanical arms can totally supplant our hands and work for people.

At present, KEYES group has designed this kind of smart mechanical arm car to tackle the shortcomings of most robot arms, clumsy and fixed. This mechanical smart car reacts and performs its functions by following commands sent by the cellphone connected.

Features

Multi-purpose Function: Anti-fall, obstacle avoidance, following, IR remote control, line tracking, automatically convey and so on.

Easy to Build: soldering circuit is not required.

High Tenacity: high performance car baseplate and metal mechanical arm

High Extension: expand other sensors and modules through motor driver shield.

Multiple Controls: IR remote control, fully automatic and App control(iOS and Android system)

Basic Programming:C language code learning.

Specification

  • Working voltage: 5v

  • Input voltage: 7-12V

  • Maximum output current: 3A

  • Maximum power dissipation: 25W (T=75℃)

  • Motor speed: 5V 63 rpm / min

  • Motor drive form: TB6612 drive

  • Ultrasonic sensing angle: <15 degrees

  • Ultrasonic detection distance: 2cm-400cm

  • Bluetooth remote control distance: 20-50 meters (measured)

  • Bluetooth APP control: support Android and iOS system

Getting Started with Arduino

OpenELAB V4.0 Development Board

You need to know that OpenELAB V4.0 development board is the core of this smart car.

OpenELAB V4.0 development board is an Arduino uno -compatible board, which is based on ATmega328P MCU, and with a cp2102 Chip as a UART-to-USB converter.

It contains everything needed to support the microcontroller. Simply connect it to a computer with a USB cable or power it via an external DC power jack (DC 7-12V) or via female headers Vin/ GND(DC 7-12V) to get started.

The following code is used to initialize the angle value of servo. Copy the code in the Arduino IDE and plug in power, then three servos will rotate to an initial angle.

Wiring Diagram

Note: servo 3 sits on the base

Test Code

#include <Servo.h>	
Servo myservo1;		//servo of claw
Servo myservo2;		//servo of arm
Servo myservo3;		//servo of base
int k1=90,k2=120,k3=90;  // initialize the angle value of three servos

void setup(){
  Serial.begin(9600); //set baud rate to 9600
  myservo1.attach(11);//Servo1 is connected to D11
  myservo2.attach(10);//Servo2 is linked with D10
  myservo3.attach(9);//Servo3 is linked with D9
  myservo1.write(k1);//make servo 1 rotate to 90°
  delay(1000);
  myservo2.write(k2);//make servo 1 rotate to 1200°
  delay(1000);
  myservo3.write(k3);//make servo 3 rotate to 90°
  delay(1000);
}
void loop(){
}

Projects

Project 1: LED Light

1. Description:

For starters and enthusiasts, LED Blink is a fundamental program. LED, the abbreviation of light emitting diodes, consists of Ga, As, P, N chemical compounds and so on. The LED can flash in diverse color by altering the delay time in the test code. When in control, power on GND and VCC, the LED will be on if S end is in high level; nevertheless, it will go off.

2. Specification:

  • Control interface: digital port

  • Working voltage: DC 3.3-5V

  • Pin spacing: 2.54mm

  • LED display color: red

3. What You Need:

4. Wiring Diagram:

The pin -, + and S of LED module are connected to G, V and D3 of shield.

5. Test Code:

/*

 lesson 1.1
 Blink
 http://www.OpenELAB.io
*/
void setup()
{
  pinMode(3, OUTPUT);// initialize digital pin 3 as an output.
}
void loop() // the loop function runs over and over again forever
{  
  digitalWrite(3, HIGH); // turn the LED on (HIGH is the voltage level)
  delay(1000); // wait for a second
  digitalWrite(3, LOW); // turn the LED off by making the voltage LOW
  delay(1000); // wait for a second
}

6. Test Result:

Upload the program, LED flashes with an interval of 1s.

7. Code Explanation:

pinMode(ledPin,OUTPUT) - This function denotes that the pin is INPUT or OUTPUT.

digitalWrite(ledPin,HIGH) - When pin is OUTPUT, we can set it to HIGH(output 5V) or LOW(output 0V)

8. Extension Practice:

We succeed in blinking the LED. Next, let’s observe what LED will change if we modify the delaying time.

/*

 lesson 1.2
 delay
 http://www.OpenELAB.io
*/
void setup() {  // initialize digital pin 11 as an output.
   pinMode(3, OUTPUT);
}
// the loop function runs over and over again forever
void loop()
 { digitalWrite(3, HIGH); // turn the LED on (HIGH is the voltage level)
   delay(100); // wait for 0.1 second
   digitalWrite(3, LOW); // turn the LED off by making the voltage LOW
   delay(100); // wait for 0.1 second
}//****************************************************************

The test result shows that the LED flashes faster. Therefore, we can draw a conclusion that pins and time delaying affect flash frequency.

It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, 2 ICSP headers and a reset button.
