To build a car that travels 5 meters and shoots a target sideways, consider using a combination of computer-controlled servos and a drive-by-wire system for precise movement. A laser guidance system can help align the shot accurately, while a GPS locator can time the shooting mechanism. While unconventional suggestions like using an Aston Martin and an AK47 were mentioned, they are impractical and not suitable for a homework project. Focusing on simpler mechanisms and creative engineering solutions will yield better results. Engaging in collaborative brainstorming can enhance the development of effective ideas for this project.
