A Function Generator that We built by following a simple circuit during our academic life.

We used a comparator circuit for a square waveform and two integrator circuit for a triangular and a sin waveform. We used practical integrators to overcome the effects of offset and bias current that’s why we used a resistor parallel with the capacitor, R6 and R5 larger than R1 that gives negligible effects on the output waveform. Thus we built the circuit and determined the output waveform. Clients can easily integrate this easily and check various waveforms as they want. Lastly, We can say the generator we built is much more cost effective than others in the market.

A Spy Robot that we designed to assist Military Activites built by Ocean Group.

The main objective of this project is to study the main components of the robot, the system is communicated by using a transmitter and a receiver, the robot motion is controlled by using DC servo motor and sensing devices and build a six‐legged walking robot that is capable of basic mobility tasks such as walking forward, backward, rotating in place and raising or lowering the body height. Our machine can help the military community by securing their life. Our Robot can reach that places which is very dangerous for mankind and all humankind. Besides, We can use it on various life saving purposes.
