Introduction There any risks associated with the bench press, especially if the user does not employ the help of a spotter This interactive mechatronic system can be used to significantly decrease injuries by interacting with the user and monitoring his or her activity while using the bench press This project is a cost effective system that can be used to facilitate safety in the gym environment 3

Project Overview Objective: to design a smart bench press system and demonstrate its capabilities

Project Overview Objective: to design a smart bench press system and demonstrate its capabilities by building a prototype An automatic actuator monitors the user activity and detects indications of struggle Once sensing struggle, the system will engage Once engaged, the system will use an arm actuator system to help the user lift the bench press Additional features improve the workout experience 4
