Team : Tyro

Introduction:

Tyro is a team of 12 members.All member have worked in their field.We are working on several project like:

humanoid robotautomation of home light, all terrain vehicle

We have participated at national level event held at IIT ROORKEE, IIT JODHPUR AND PANT

NAGAR and won 1st, 3rd, 2nd prize respectivelyWe also have several exhibition certificate.

What is a RobotDefinition of robot:

Any machine made by by one our members: Robot Institute of America

A robot is a reprogrammable, multifunctional manipulator designed to move material, parts, tools or specialized devices through variable programmed motions for the performance of a variety of tasks: Robot Institute of America, 1979

What Can Robots Do1.Jobs that are dangerous for humans

2.Repetitive jobs that are boring, stressful, or labor-intensive for humans

Material handlingMaterial transferMachine loading and/or unloadingSpot weldingContinuous arc weldingSpray coatingAssemblyInspection

Cleaning the main circulating pump housing in the nuclear power plant

Machine loading and/or unloading

Robot Mechanism: Mechanical Elements

Gear, rack, pinion, etc.

Chain and sprocket

Lever

Cam and Follower

Linkage

Our work in field of robotics

This bot was prepared during our 1st year.It was a defending typeROBO.

EQUIPMENT USED:

4 high torque DC motor4 plastic wheelmild steel sheetwired remote (constructed manually)

ROBOTICSLINE FOLLOWER

ATMEGA8

It is a low power CMOS(Complementary Metal Oxide Semiconductor) 8 bit microcontroller based on the AVR architecture.

• Microcontroller consists of a Microprocessor which is interfaced to RAM and Flash memory.

• Features: It has 8 KB of flash memory 512 bytes of EEPROM 1 KB of SRAM 23 general purpose I/O lines 32 general purpose working registers

PROGRAMMING

• Program is written in C language.

• Code is written to give instructions to computer to perform a particular task in a particular condition.

• Code is compiled to generate machine file.

• Computer only understand this machine file which is in the language of 0 & 1.

• Now this file has been feed in the memory of the microcontroller.

MOTOR

• Two motors have been used to rotate the two wheels clockwise or anticlockwise. This provides motion to the robot.

• Motors are arranged in a fashion called H-Bridge.

.

MOTOR

• To power the motor, two switches are turned on that are diagonally opposed in the H-Bridge.

• The combination of switches that are on, decide the motion of robot whether it will go forward, backward or take turn.

• IR Analog Sensor:-

Transmitter- An infrared emitting diode.

Receiver- A phototransistor.

WORKING MODEL

• The working model of a line follower consists of two motors, one ATmega8 circuit board, two wheels, two IR sensors, LEDs, wires and power supply.

• The IR sensors get the input and according to the program the LEDs glow depending on the input. The two motors rotate together in one direction to go forward or backward. For taking a right turn, the motor at right side stops and left side one continues to rotate. This rotation depends on the program which gives instructions to the motor depending on the input that sensor gives.

• IR sensors provide the input, motors give the output and the wheels make the robot to follow a line.

WORKING MODEL

• Follower robot is a mobile machine that can follow a path. The path can be a visible black line on a white surface.

• The IR sensors receive an analog signal that depends on the intensity of light reflected by the black line of emitted beam by

the LEDs.

• These signals are sent to the ADC comparator which creates digital signals that are sent to Microcontroller.

• The microcontroller gives instructions to motor to perform work.

.

DTMF based mobile controlled Robot.

Hardware

•AVR Development board with atmega16•DTMF decoder•Mobile with 3.5mm jack•Connectors•Two dc geared motors

Software

•AVR Studio 4•WinAVR 2010•SinaProg Hex Downloader•USBasp Driver

Project tyro:

Seeing our last year project and achievement.we become more encourage to develop a more dynamic and sophisticated robot.We come with the idea of humanoid robot (tyro)

Equipment used:

12 high torque dc motor2 flipper wired remote (constructed manually)4 tyreplastic sheetrectangular hollow pipe (for skeleton structure)

Salient features:

1. It has ability to move on horizontal surface.

2. This bot has load bearing capacity around 2kg through its flipper which works as hand and and can deliver bearing load at desirable place operated through remote control manually.

Tyro team at national event:

1st national event:

After achieving series of success in field of robotics. We have decided to participate in national robowar event.
