Summary: Using pesticides in Philippine farming can be extremely harmful to farmers' health and the environment. This is primarily due to direct chemical exposure and use of unsafe spraying techniques and methods. In response to these challenges, thisstudy developed and designed a Remotely Controlled Robotic Pesticide Sprayer inspired by the above problems. The design aimsto increase efficiency in agriculture and reduce exposure to pesticide chemicals by human beings. The prototype features a steel frame body and consists of dual 24V wiper motors, wheels, and a 16-liter pesticide tank. It is operated remotely via NRF24 Mini wireless transceivers. The prototype exhibits reliable forward and reverse mobility, maintaining a consistent speed of 0.45 m/s, which demonstrates the sprayer's capability for steady movement in farming environments. The robot's rotation mechanism was effective; thus, turning performance showed potential for further refinement. Sprayer range evaluations revealed effective chemical distribution, with average coverage areas of 330 cm2 for the left nozzle and 264 cm2 for the right, indicating strong spraying performance. Communication tests recorded responsive control within a 5-meter range, with an average system response time of 1.27 seconds. Stability assessments under a full 15-liter load confirmed the robot's structural reliability, and battery runtime tests averaged 4.32 minutes under typical operating conditions. In a structured user evaluation, the prototype received a rating of 4.41, classified as "Very Good." These findings suggest that the Robotic Pesticide Sprayer is a reliable and effective solution for modern agricultural practices, promoting greater safety, productivity, and accuracy in pesticide application.

Using pesticides in Philippine farming can be extremely harmful to farmers' health and the
environment. This is primarily due to direct chemical exposure and use of unsafe spraying
techniques and methods. In response to these challenges, thisstudy developed and designed
a Remotely Controlled Robotic Pesticide Sprayer inspired by the above problems. The
design aimsto increase efficiency in agriculture and reduce exposure to pesticide chemicals
by human beings. The prototype features a steel frame body and consists of dual 24V wiper
motors, wheels, and a 16-liter pesticide tank. It is operated remotely via NRF24 Mini
wireless transceivers. The prototype exhibits reliable forward and reverse mobility,
maintaining a consistent speed of 0.45 m/s, which demonstrates the sprayer's capability for
steady movement in farming environments. The robot's rotation mechanism was effective;
thus, turning performance showed potential for further refinement. Sprayer range
evaluations revealed effective chemical distribution, with average coverage areas of 330
cm2 for the left nozzle and 264 cm2 for the right, indicating strong spraying performance.
Communication tests recorded responsive control within a 5-meter range, with an average
system response time of 1.27 seconds. Stability assessments under a full 15-liter load
confirmed the robot's structural reliability, and battery runtime tests averaged 4.32 minutes
under typical operating conditions. In a structured user evaluation, the prototype received
a rating of 4.41, classified as "Very Good." These findings suggest that the Robotic
Pesticide Sprayer is a reliable and effective solution for modern agricultural practices,
promoting greater safety, productivity, and accuracy in pesticide application.
