3. | Line following Robotic vehicle that does not require any microcontroller interface or program: An array of two pair of photo sensors comprising IR transmitter and photo diode is fitted in front of the car to detect a black path as well as any turns in the path. By reading the outputs from each of the two sensors, darlington pair of transistors is biased. Two DC motors are connected to the collector of the transistor TIP122. The motors are able to turn the steering left or right, depending on what logic signal the sensor sends. |
4. | Cell phone operated Robotic vehicle: Robotic vehicle that can be operated from any where using cell phone sent commands. Once the contact is established over dialing the cell phone mounted on the robotic vehicle it accepts the tone commands thereafter for the operation of the vehicle. |
5. | Cell phone operated Saga Robot: Digit commands from one cell phone sent to another cell phone mounted on the robot to receive the DTMF (Dual Tone Multi Frequency) mode commands to feed to a microcontroller, to operate 2nos DC motors through motor driver IC for any direction movement. |
6. | War field land rover that alerts on sensing planted land mine: Wirelessly controlled land rover mounted with metal detecting sensors to generate alarms on sensing planted land mine. The movement is wirelessly controlled by a hand held RF transmitter to send commands to the RF receiver mounted on the land rover. |
7. | War field sage Robot that alerts on sensing planted land mine ahead: Remotely controlled robot using RF mode with encoder and decoder duly interfaced to a pair of microcontrollers for movement and metal detection by a metal detector (Land mine detector) being actuated after the robot reaches the suspected site. |
8. | Bomb displacing Robot with tension controlled soft catching arm: A moving Robot control wirelessly to reach the suspected bomb site to relocate the bomb at different place while handling the same carefully by a soft catching arm duly controlled by interrupt monitored motor to avoid extra pressure on the suspected object for safety reasons. |
9. | Wireless operated Fire Extinguisher vehicle with water jet spray: Fire extinguisher vehicle loaded with water tanker and pump controlled remotely over wireless to throw water jet to the fire. The movement and the pump control are wirelessly controlled by a hand held RF transmitter to send commands to the RF receiver mounted on the fire extinguisher vehicle. |
10. | War field spying Robot with night vision wireless camera: A RF based moving vehicle mounted with wireless night vision camera controlled remotely over wireless to send real time pictures of enemy activities in war field. The movement is wirelessly controlled by a hand held RF transmitter to send commands to the RF receiver mounted on the moving vehicle. |
11. | Line following Robotic vehicle using microcontroller interface: Using IR reflected light falling on photodiodes form as input to IP parts of MC to drive a robotic vehicle motor through motor driver IC in a specified black path by reflection from the white surface and then by disabling any one motor in the event of reflection being stopped while going away from the black path to take turn till the reflection resumes. |
