This research aims to design and build a teleoperating system that allows for the control of the four-wheeled robot using commands sent over a WiFi connection. The research consists of three basic parts: the program, circuit, and the mechanical parts. The research highlights the ability of a WiFi connection to foster the exchange of live streaming video and proximity alerts besides the actual control of the robot. The program is a Visual C++ based code while the circuitry consists of a microcontroller (PIC16F84), voltage regulators (LM317 & LM723), SCR2 to TTL converter (MAX232), Full-Bridge motor driver (L298), an ultrasonic sensor, and batteries. The mechanical parts include two DC motors with the necessary shafts and gears. To prove the robot performs within the designed limits, the following experiments were made: average speed experiment, displacement, incline test, maximum range, obstacle, and response time test. The experiments have proven that the robot can perform within the promised limits. This shows that the WiFi connection (and the technology in general) was stable enough to accommodate the information sent between the controller and receiver. The main objective was executed within the acceptable limits.
