A Quadcopter , also called a quad rotor helicopter or quad rotor is a multi-rotor helicopter that is lifted and propelled by four rotors .Quad copter are classified as rotorcraft, as opposed to fixed-wing aircraft, because their lift is generated by set of rotors(vertically oriented propellers)..Quad copter generally use two pairs of identical fixed pitched propellers; two clockwise (CW) and two counter clockwise (CCW).These use independent variation of speed of Each rotor to achieve control. By changing the speed of each rotor it is possible to specifically generate a desired total thrust; to locate for the center of thrust both laterally and longitudinally; and to create a desired total torque, or turning force.
OBSTACLE AVOIDING IN RASPBERRY
The obstacle avoidance robotics is used for detecting obstacles and avoiding the collision. This is an autonomous robot. The design of obstacle avoidance robot requires the integration of many sensors according to their task, The obstacle detection is primary requirement of this autonomous robot. The robot gets the information from surrounding area through mounted sensors on the robot. Some sensing devices used for obstacle detection like bump sensor, infrared sensor, ultrasonic sensor etc. Ultrasonic sensor is most suitable for obstacle detection and it is of low cost and has high ranging capability..
Swarm Robotics
Swarm robotics is a new approach to the coordination of multi robot systems which consist of large numbers of mostly simple physical robots. It is supposed that a desired collective behavior emerges from the interactions between the robots and interactions of robots with the environment..It Deals with the Master Slave Configuration, The Master gives the Command to the Slave robot .Master Will be having the sensors connected to it both robots run in NOVABOARD(atmega-328).Their communication link via Bluetooth(HC-05).The master robot pairs to the slave robot automatically and is programmed in HC-05.
Internet Of Things (IoT)
The next big thing in a more connected world is internet of things, to control/monitor electronic/mechanical devices, automobiles and other physical devices connected to the internet. With IOT user can control more than digital things easily through a comfortable GUI over the internet.
Image Processing Project
Image Processing provides a comprehensive set of reference-standard algorithms and workflow apps for image processing, analysis, visualization, and algorithm development. You can perform image segmentation, image enhancement, noise reduction, geometric transformations, image registration, and 3D image processing..
GESTURE CONTROLLED ROBOT
Gesture Based Robotics deals with robots which involve human-machine interaction – where a robot is controlled through hand movements. The robots take inputs from accelerometer sensor and are controlled by programmed NOVABOARD(At mega 328 Development Board),This project-based course helps participants understand the concepts and use of accelerometer sensor, microcontrollers and other electronic components in Robotics. It mostly includes practical training on building robots based on gesture recognition technology, providing students a glimpse into Human Machine Interaction technologies.
DTMF CONTROLLED ROBOT
The DTMF robot machine is controlled by the mobile signals, in which we make a call to the mobile phone which is inter connected to the DTMF robot operated at auto answer mode, based up on the instructions given by our cell phone the robot operation depends our mobile acts as an remote control for the robot,the robot. DTMF stands for dual tone multiple frequency based on this the robot movements are controlled. These DTMF mechanical systems find applications in military security actions like spy robot for bomb detection, in industrial security, controlling house hold appliances, for long distance remote sensing systems. If we implement a Wireless CMOS Camera interface with the robot we can obtain the pictorial information also..
LINE FOLLOWER
The line follower is a self operating robot that detects and follows a line that is drawn on the floor. The path consists of a black line on a white surface (or it may be reverse of that). The control system used must sense a line and maneuver the robot to stay on course, while constantly correcting the wrong moves using feedback mechanism, thus forming a simple yet effective closed loop System. The robot is designed to follow very tight curves..
