Are there any components compatible with EV3 that are more powerful and durable? Are there components compatible with EV3 like motors, sensors, brackets, other details that I can easily connect to an existing EV3 main block and build something to do real-life tasks? Like transporting weights on the route, cocktail maker that could handle glass bottles, home cleaner that can put objects in the order.
Look at Tetrix or Matrix. Theese building systems have more porefull motors than NXT ones. Metal blocks allow you to create strong robots. Tetrix and Matrix robots can be controlled by NXT/EV3.
