Have you encountered The Shadow Caddy before?
It’s essentially a robotic golf caddy that will happily carry your bag about as you play, tracking your movement through a little receiver you slip into your pocket before embarking.
While it does strike me as a bit decadent, it excites me to see real-world applications for personal robots. What if this device was modified to become a guide for the blind?
If you were to create some sort of verbally-interactive GPS, you’d be well on your way to allowing the visually impaired greater freedom of movement – and the little beast looks well-built for hauling groceries.
