The block diagram of Final Year Mechanical Project clearly shows the functional working of gps that is here the set point (current position) is compared the first waypoint. Once the destination is reached the program memory enqueue the second way point and so on. If the designated waypoint is not reached again it checks till the destination is reached. 

Performing the Navigation Using GPS and Camera:

The effective way of using adaptive robotic technology is performing the complex operation simultaneously to do the desired operation. Similarly we have performed the simultaneous operation by performing both obstacle avoidance and positioning using stereo camera and gps sensor respectively. The main advantage of performing this GPS Navigation Robot operation is maximum nearness error can be avoided that is created during real time positioning. The block diagram clearly shows how the navigation is performed.

Robotics Final Year Project Ideas and Topics

Constructional Working of Robotics:

Electronic Engineering ECE Approach:

Camera:

In our Robotics Final Year Project we have two cameras

a) C-MOS camera sensor

b) Stereo camera

          The C-MOS sensor camera is placed at the center of the bot and the stereo camera is placed at the center of the bot and the stereo camera is placed at the top of the bot. the camera is tilt to an angle to make the projection perfectly projected to the center of the object.

The C-MOS camera is used to perform more specifically for the lane detection. It is used because of its very high sensitivity to light, low power consumption and low cost. The output is digital, so it is directly fed to the controller to take the action. The functional block diagram shows the importance of camera action.

Technical Features of the Robotic Camera:

The Image processing and Image acquisition is performed by the on-board micro processor and the result of stereo and C-MOS camera is stored in SRAM (Static Random Access memory) and DRAM (Dynamic Random Access Memory) respectively.

The lane following is pre processing method, so the sample of images are pre loaded to the SRAM and it’s been cross checked by the controller and necessary action is given to the end effector. 

          The Dynamic image processing is carried out by using stereo camera where the self-windowing algorithm is used for real time variation. It is been stored in DRAM and synchronously signal is given to controller to perform the end- effector action.

Mechanical Engineering Projects on Robotics

The computational robotic feature was developed using a mechanical system engineering approach with emphasis placed on the understanding the inter-relationship between system components and on maximizing the overall system performance.

The Mechanical Engineering Project development of fully autonomous is a very complex task which holds the consideration of several factors. First, the appropriate view of providing and utilizing autonomy must be determined for each application. For example, the sensors used in this robotic project for image analysis and global positioning is high a time-variants, so this will directly create impact on any set of tasks designed.

Here we tried to manipulate the entire operation carried out by the Robotics Engineering itself that is it has its own capacity to take any decision under any environment without interference.

The integration is very difficult because it requires the assembly of many complex sub systems into a high degree of interconnection and synchronization.

From a Mechanical and Electronic engineering perspective, a well-defined architect provides the underlay framework for achieving reliable maintainable cost-effective system. N Such architecture does this by enabling methods coherently integrating diverse physical, functional and disciplinary sub-systems.

Robotic Projects for Mechanical Engineering Students

Our Robot Mechanical Project design concentrate on working with real time environmental variation and least power consumption device. The main approach of the bot to a particular situation is based on the micro controller and processors which en-route to perform serious mechanical and electronic operation. We use two standard camera C-MOS camera and Stereo camera to perform lane detection and obstacle avoidance respectively. Controller controls the camera action, GPS sensor, motor drivers and according to varying environment. Lane detection and obstacle avoidance is done by using image processing. The controller performance of Robotic Projects for Mechanical Engineering Students is concentrated mainly to navigate on any surface under any condition. The different driver circuits and interfacing units are used to integrate the mechanical element with electronic components. The control signal is sent to standard bus controller from the various controlling system. The low power consuming sensors and controllers are used to perform the action. Indirectly we are concentrating on minimizing power wastage.

Main aim of the Mechanical System:

The dimensions of the mechanical engineering projects robot are 1600*965*810 mm which is based on the design modeled in pro-e modeling. The kinematic approach to build the bot is based on the chain linkages; we have used Double Rocker Mechanism. With the presence of linkages there is no separate suspension mechanism needed. At all point of times and at all positions always all six wheels will be touching the ground. This is the most advantageous point of having linkages.

The locomotion of bot is designed with six wheels so that the stability of the vehicle is high. All the wheels are given independent drives by each wheel setup having a motor. In addition, four servo motors are placed in the front and back wheels. So the wheels can be turned to steer in any direction. The wheels if properly turned to the required angle, the entire vehicle may completely turn in its position up to 360°. The speed of the vehicle is also controlled by PWM i.e. minimizing the voltage supply given to motors. Hence in overall the bot is designed to move autonomously on all terrains and crossing all obstacles.

Conclusion of this Robotic project Report:

Our mechanical engineering project- pipe inspection robot is extended to identify the history of navigation from the time of start to current running location at various intervals by providing separate internet protocol (IP) based server to note the event history. This could be accessed only by the administrator.

Peristaltic Pumps Mechanical Seminar Topic

Introduction to Peristaltic Pumps Mechanical Seminar Topic:

Peristaltic Pumps are one of the most common items that we find in our house premises; a peristaltic pump is one of the displacement pumps which are positive in nature and is used to pump various kinds of fluids. The name “Peristaltic pump” was derived the word “peristalsis” which is its pumping principle. It consists of a flexible tube, rotor with rollers, shoes or wipers, pump casing etc. The fluid is kept inside the flexible tube or hose which compress and relaxes making the inward and outward flow of the fluid. For that rollers attached with the rotor, shoe and wipers are attached to the external surface of the tube which initiates the compression and relaxation. When the rotor gets started, an under compression tube part closes compelling the liquid to move through. A cam is passed then to make the tube regain its original shape and the fluid flow is induced back to the pump, this process is called restitution.

Advantages of Peristaltic Pumps:

  • Only the interior part is in touch with the fluid and as a result there are less chances of contagion
  • Absence of valves or glands means less maintenance and manufacturing costs
  • No Product slip, linear speed flow makes it ideal for dosing
  • No priming needed, peristaltic pumps are self-primed and seal less with no cavitation
  • Various types of fluids can be pumped
  • Powerful suction and low vacuum force
  • Can handle fluids under high pressure flow

There are many areas where a peristaltic pump can be used; the most common industry which it is used is the water treatment plants where the pumps are used to induce chlorine and other chemicals into running water. Other major industries include paper, ceramic, beverages, detergent, construction etc.  Peristaltic pumps are also used as medical equipment in dialysis machines or bypass machines. Due to its ability to handle high suction pressure it is even used in nuclear plants.
