Well done Kiara, this is such a thoughtful invention that you have thought up! It would be life changing for people who struggle to walk as well as helping them to carry anything that they need along with them! I love that you have thought about the charge lasting for a long time so that people using your Clever Walker could use it whenever they need it! I wonder if you could think about the possibility of charging the invention using a sustainable energy source? Your drawing is brilliantly explained too, fantastic! Keep inventing!
