Choose the stage of Innovation you’ve submitted::

Choose the stage of Innovation you’ve submitted: Idea: The field of rescue robotics is seeking to develop the closest possible relationship between humans and machines in emergency situations, leading the way to the possible substitution of men by machines, based on their autonomy. The main aim of this project is to perform search and rescue operations during Natural Calamities like Earth Quakes, Fire Accidents etc Prototype : We have designed our kit using PIC Micro controller (16F877A) Regulated power supply (RPS) DC motors drivers DC Motors Servo Motors RF transmitter and receiver Camera and thus developed a real time model and thus obtained the results Idea Prototype Established Scaling PROTOTYPE IDEA

The Innovation:

The Innovation Chosen industry : Public Services . Chosen technologies: Mobility Objective : The main aim of this project is to perform search and rescue operations during Natural Calamities like Earth Quakes, Fire Accidents etc Approach : This basic approach leads to an implementation where the head servo angle solely defines the motion, and a buffer stores the history of head angles for the rest of the servo angles. The implemented circular buffer have a number of slots between each servo, such that all slot- steps in the buffer would result in having a given servo angle appearing at the next servo. The speed of stepping forward in the buffer thus defines the speed of intended snake movement. Describe the innovation developed :The module design of the snake robot will consist of a head engine drive bot which will act as the direction control for the entire design. The bots behind this head engine will act as the body of the snake which will perform the desired functionalities. These additional bots will not only perform a sine wave motion resembling a snake but will also have separate compartmental spaces to house the hardware related to other functionalities that can be added later. These individual bots are connected to each other through a screw and nut arrangement with washers provided in between to reduce the friction between the screw and nuts. Furthermore the nuts are not tightened fully and are left a little loose in order to allow for free angular movement of the bots specially while taking sharp turns.  

Compelling need for the innovation:

Compelling need for the innovation Existing System : Existing robot designs are purely uni -functional in nature and are designed and manufactured to be able to perform specific tasks. Deployment in any other new application calls for a completely new design procedure in terms of architecture.   Disadvantages of existing systems   Uni -functional in nature Limited to certain applications Limited modularity and robustness Cost of implementation per robot deployed will be more. Efficiency of intended applications is limited.

Impact:

Impact Proposed System   The snake robot intended to be designed will move around in a serpentine motion and theoretically speaking is the best movement for any robot to have. Any number of additional bots can be added with no specific change in architecture design. Only the length of the snake robot will increase.   The snake robot has several distinct features which ordinary bots can’t boast of Agile movement over any terrain. Includes movement through water and other fluids. Can scale trees and vertical poles as well. Small size. Ability to be camouflaged and mistaken for a real snake. Multiple functionality in a single snake robot device.  

Implementation:

Implementation Working Principle:  This basic principle leads to an implementation where the head servo angle solely defines the motion, and a buffer stores the history of head angles for the rest of the servo angles. The implemented circular buffer have a number of slots between each servo, such that all slot- steps in the buffer would result in having a given servo angle appearing at the next servo. The speed of stepping forward in the buffer thus defines the speed of intended snake movement. User Requirement This project is implemented using hardware already listed and the following software : Express PCB – for designing circuit. PIC C compiler - for compilation part. Proteus 7 (Embedded C) – for simulation part. Front view of the head engine bot Top view of head engine and an additional bot

Conclusion & Future Scope:

Conclusion & Future Scope Biological1y inspired robots (specifically, snake— and worm-like robots with modularity and hyper-redundancy) generally perform detection and identification of victims an path planning in search of survivors to be rescued using decision and control methodologies from the aforementioned concepts without collision. Serpentine mechanisms, with their wide range of capabilities, face major design challenge mechanism design, path planning, control, and sensor integration. This research addresses control and sensor integration path planning and an actuated joint module that is design and implemented as the basic component of a serpentine rob platform. A number of such modules can be connected in desired way to create a simple yet flexible hyper-redundant serpentine structure. Some of the features of such mechanisms and possible locomotion modes are discussed with relevant experimental performances. The applicability of such serpentine structures adapting to different environmental situations and locomotion requirements is not limited to just Search and Rescue operations but can be extended to a multitude of applications.   Future Scope: 1. Military environments for acts of spying and espionage. 2. Industrial environments such as in oil industry to detect and transmit images of oil spills and leaks originating inside the oil pipelines. 3. During times of natural disasters such as earthquakes to search through rubble for survivors. Its’ ultra-thin design and versatile movement make it ideal for movement through debris. 4. In marine operations to study the ocean seafloors and observe marine wildlife from close quarters by infiltrating their environment. The snake robots size and movement make it ideal for under water operations as well.
