BAHRIA UNIVERSITY Karachi Campus DLD - Project Proposal Form Project title: Remote Operated Spy Robot Class: 2-C Department: BS(CS) Key Project Contact: • Name : Uroosa Mahmood Alam • Role : 02-134171-005 • Phone number : +92 302 2522756 • Emai : umamaths@hotmail.com Project Participants : Student 1: Uroosa Mahmood Alam Student 2: Saad Ahmed Khan Student 3: Osama Khan Student 4: Samina Naaz Project Description : We are designing a spy robot which can be controlled by the remote. The maximum controllable range is 125 meters. The remote has four switches to control the robot in four directions. The robot senses the surroundings through the CCD camera and sends to the receiver through the Radio Frequency wireless communication. Components : HT12E encoder HT12D decoder RF 433 MHz Transmitter and Receiver L293D motor driver Wireless CCD camera push buttons – 4 DC battery – 12V, 1.3 Ah 9V DC battery Robot Resistors – 33k,750k SPST switch – 1 NOT gates – 4 Project Principle : When we press any key in remote, the HT12E encoder generates 8 bit address and 4 bit data. Then ASK (Amplitude shift keying) transmitter sends 8 bit address and 4 bit data to the receiver. At the remote section DIP (dual inline package) switches are used to set 8 bit address. Receiver receives these 12 bit data and
