Line follower robot

What is a robot?

—A robot is a mechanical or virtual agent that can perform tasks automatically or with guidance, typically by remote control.

—A robot is an electro-mechanical machine  that is guided by computer and electronic programming.

REQUIREMENT OF THE LFR

 

—The robot must be capable of following a line.

—

—It should be capable of taking various degrees of turns

—It must be prepared of a situation that it runs into a territory which has no line to follow. (Barren land syndrome)

—The robot must also be capable of following a line even if it has breaks.

—The robot must be insensitive to environmental factors such as lighting and noise.

—Scalability must be a primary concern in the design.

—The color of the line must not be a factor as long as it is darker than the surroundings.

MICRO CONTROLLER BASED LFR

—

    

This LFR is a versatile and feature rich robot development platform. The LFR is based around the popular 8051 family micro controller

  SPECIFICATIONS

—2 IR based Line sensors

—2 IR based obstacle detection sensors

—Mechanical Construction:

—Two wheel drive with front skid

—High quality Acrylic laser cut chassis

—Plastic wheels with rubber grip

—2 x 100rpm Motors

—Driven by 8.4V rechargeable AA size NiMH battery pack

—9 V Power Supply 

 WORKING OF LFR

MOVEMENT OF LFR

 USES 

—Industrial automated equipment carriers

—Tour guides in museums and other similar applications.

—For repetitive tasks which use the same path things like following one on the floor of a factory to remove the need for a human operator also lines of metal placed under lawns can be used as a guide...

—Swarm robotics is one of the major application

  

Swarm robotics

Swarm robotics is a new approach to the coordination of multirobot systems which consist of large numbers of mostly simple physical robots.

 

LIMITATIONS

—Choice of line is made in the hardware abstraction and cannot be changed by software.

—The steering mechanism is not easily implemented in huge vehicles and impossible for non-electric vehicles (petrol powered).

— Few curves are not made efficiently, and must be avoided.
