Blundering Botics: Workshop Series

Workshop Series

This page contains information and links related to a series of workshops offered summer 2009 entitled An Introduction to Embedded Controllers with Robots.

Slides

Part I - Introduction to Robotics, Electronics and Embedded Microcontrollers.

Part II - The Core Topics of Microcontrollers.

Resources - Tutorials on TRC

I've posted a series of tutorials on the Trossen Robotics Community site. These tutorials closely follow much of the material we've covered in our course.

So You Want To Build A Robot? - my version of a "Start Here".

Choosing Sensors for Your Robot - covers most major sensor groups.

Introduction To Interrupts - includes a discussion of Pin Change Interrupts.

Materials for Your Robot - structural materials for your bot.

Power Supply Basics - very basic coverage of power supply parts.

AVR Basics - this goes more into depth about the AVR registers (still a work in progress).

Code Examples - Part I

These should copy directly into the Arduino Environment without issue.

 
// AVRRA Mini Demonstration Code
// This code will blink an LED tied between PB1/D9 and GND.

void setup(){		// this is called once
    pinMode(9,OUTPUT);
}

void loop(){		// while(1){loop();};
    digitalWrite(9,HIGH);
    delay(500); 	// this halts the proc
    digitalWrite(9,LOW);
    delay(500);	// for half a sec.
}

 
// AVRRA Mini Demonstration Code
// This code will use a switch to turn off an LED
// Wire switch between PC2/A2 and ground

void setup(){		// this is called once
    pinMode(9,OUTPUT);
    pinMode(16,INPUT);
    // turn on pull-up resistor!
    digitalWrite(16,HIGH);
}

void loop(){		// while(1){loop();};
    digitalWrite(9,digitalRead(16));
    delay(25);	
}

 
// AVRRA Mini Demonstration Code
// Testing serial port using XBEE radio.

void setup(){    // this is called once
    Serial.begin(38400);
}

void loop(){    // while(1){loop();};
    Serial.print('Hello World\n');
    delay(2000);	
}

 
// AVRRA Mini Demonstration Code
// See output of GP2D120
#include <SharpIR.h>

// This is a C++ class instance
SharpIR frontIR = SharpIR(GP2D120,0);

void setup(){		// this is called once
	Serial.begin(38400);
}

void loop(){		// while(1){loop();};
	Serial.print(frontIR.getData());
	delay(2000);	
}
// SharpIR is located in
// /usr/arduino/hardware/libraries/

 
// AVRRA Mini Demonstration Code
// Drive robot around a little bit
#include <Motors.h>
Motors drive = Motors();

void setup(){		// this is called once
	Serial.begin(38400);
	// drive.set(left speed, right speed)
	drive.set(150,150);
	delayms(2000);
	drive.set(-150,150);
	delayms(2000);
	drive.set(0,0);
}

// Motors is located in
// /usr/arduino/hardware/libraries/
