INSPIRATION BEHIND THE PROJECT

 

The basic aim behind the project is to realize the hard real time system, with the help of embedded systems. When we were going to choose our Final year project at that time “Space Research Center NASA” had started a program to send an autonomous robotics system to MARS for carrying out advance research in space science. This incidence provided enough inspiration to start a robotics project. So, we decided to simulate that NASA project in a model, which can work just like that, but in small space i.e. lab space only.

 

So, this gave birth to The PIONEER…………..

      

 

 

INTRODUCTION TO PIONEER

 

The “Pioneer” has been chosen by me as a Final Year Project, for Session 2003-2004. I chose to build a computer controlled motorized robot that would be able to maneuver about a four wheeled wooden base with the help of embedded programmed microcontroller unit.

Pioneer has been designed to work as an autonomous path finding system. The system owns a capability to move within the desired range, without actually bumping into the obstacles. The obstacles are detected at distance of about ½ meter and suitable action is decided by the system thereat. The decision is taken based on the program that has been fed into the micro-controller.

 

The pioneer is also completely computer controlled it can be stroll in the environment in any direction with a single click on the computer; it also exhibits a unique capability of continuously sending its locations and direction to the remote terminal where user can track its position and take a decision accordingly. And all this communication is done wirelessly with the help of radio frequency.

 

Before starting the pioneer I had studied so many projects in the field of robotics. I got this idea that almost every other robot has some common features like hurdle detection, with some extra capabilities so I also decided

 

To add some unique features in the robot, which are all new as far as the new entrants in this field are concerned

At the time of the writing of this paper, the Pioneer is capable of moving forward, backward, turn left and turn right over level surfaces. It implements simple obstacle detection using a dual forward looking infrared emitter/detector pair, also completely computer controlled and with the ability of sending its direction to the controlling node.

 

          OBJECTIVES OF STUDY

The objectives of the study, which this report is based on, are to gain knowledge within the fields of robotics and machine control. The following objectives are specified:

  • Gain knowledge about hardware interaction.
  • Gain knowledge about robotics.
  • Gain knowledge about wireless machine control.
  • Learn how to use programming language in the different field.
  • Gain knowledge about Parallel Port interfacing.
  • Be able to unite the above mentioned objectives in one task and perform it.

 

 OBJECTIVE OF THE PROJECT

 

I want to build a path finder robot which can stroll in any environment with out getting stuck at the obstacle, which can be controlled by the computer and able to send its position and direction to the controlling node.

The primary design criteria for Pioneer were as follows:

 

Ø      Minimal cost

Ø      Incorporate already-owned components

Ø      Use cheap and easily-worked materials for platform

Ø      Minimize weight to make use of cheaper motors

Ø      Robustness

Ø      Solid design and construction

Ø      Able to be implemented in stages

Ø      Modular design

Ø      Room for expansion

 

 PIONEER FEATURES

 

Ø      Hurdle detection and avoidance.

 

Ø      Two way control

Autonomous

User Controlled

 

Ø      Radio wave communication with the control panel in both directions i.e pioneer to the control panel & vice versa.

 

Ø      Continuous graphical presentation of the control parameters as :

Spatial position (XY co-ordinates)

Gear control

Direction

 

Ø      Easy to operate and interactive graphical user interface.

 

Ø      Capability to adapt according to the situation phased at run time.

 

Ø      Range detection.

 

Ø      Complete Utilization of hardware resources.

 

 

 

TEAM MEMBERS

 

The team consists of three members. They are-

·         Dushyant Joshi (Team Leader)

·         Ankur Aggarwal (the Great)

·         Vishal Bhushan Jain(the genius)

 

DIVISION OF LABOR

 

We all are working as a unit and want to develop the best robot. Due to the complexity of the project we break the project into a number of modules and assign each member a different module according to his choice and interest. It will be a challenge to all of us (team member) to build this type of project which has the different type of demanding features. We learn many new things to build the project and we also apply principles of team management and software engineering to develop it .We are currently be working on the different modules as follows:-

 

 

 

Dushyant joshi

 

Vishal Bhushan Jain
