Abstract— Practical learning is essential in improving the understanding of the fundamentals of engineering and technology. Nonetheless, the availability of cheap and practical robotics kits is lacking among beginners and organizations that do not have enough budget. In this regard, this paper discusses the development of a 5 Degree-Of-Freedom wireless robotics kit suitable for learning purposes.The system design entails the use of Arduino Nano boards on the transmitter and receiver ends, and NRF24L01 wireless transmitters to facilitate live control. The robot arm employs MG995 and SG90 servos, with joint movements executed using PWM control signals. In addition, there will be a remote control consisting of a joystick and potentiometer interfaces for easy robotic arm manipulation.The system incorporates a modular mechanism design and electronic circuitry on a printed circuit board. It has been proven that the system offers smooth movement control, good wireless communications capability, and ease of assembly, which makes the system ideal for classroom learning and teaching introductory robotics
