That's very good.<p>Note lack of "we built an agricultural fruit-picking arm that can survive five years of picking".<p>Remember Tesla's robotic charging arm? [1] That was a good idea. If Tesla ever gets unsupervised autonomous driving to work reliably in parking lots, that will be useful. Then cars can self-charge.<p>(The snake arm seems complicated, but it's not. The arm is just segments, cables, and discs. The motors are all in the base. So this can be built in a way such that damaged arm replacement is about as hard as gas pump hose replacement. Snake arm robots are not used much because they have a wear problem where the cables go through the discs. But that's for painting robots, which move constantly. A charging robot makes maybe ten moves a day.)<p>[1] <a href="https://youtu.be/uMM0lRfX6YI" rel="nofollow">https://youtu.be/uMM0lRfX6YI</a>
