The final prototype is a ball projection machine powered by DC motors that serves balls to the player. To assess return accuracy, vibration sensors are placed on the opposite side of the table. When the player successfully returns a ball, the sensors detect vibrations, marking the hit as successful. The system offers consistency in practice and helps reduce dependency on a partner, enhancing solo training effectiveness.  

Idea: To build a device that can project balls towards the player and track how many returns successfully land back on the table. This enables solo players to practice reflexes, precision, and techniques in a controlled and measurable manner. Project Objectives: Enable solo training without a coach or partner. Track returns using vibration sensors to record accurate scores. Adjust difficulty levels based on player skill — from beginner to advanced. Develop reflex, accuracy, and consistency through varied ball projections. Monitor and record performance data to track improvements. Allow customization of speed, spin, frequency, and trajectory. Make table tennis more engaging and accessible for all age groups.
