I need ides about the mechanical mini projects . And needed some topics too. I've compiled a list of few mini project topics in mechanical engineering. Here's a list - 1. Design interface of aircraft / automobile cockpit: Make it easier for human interaction. 2. Study the dynamics of automobile ignition systems: Study the vibration levels of exhaust system and predict design parameters. 3. Robotics : Design and develop a mini line-follower bot. 4. Design a robot for the textile industry using SolidWorks software.
