We need it to be an ISO robotics standard and noone should buy a robot that does not either come with it, or has an option to add it to the purchase. I have two 24/7/365 robots that have used rube-goldberged mechanical mating of electrical contacts for 1A 12v charging for years. <a href="https://fosstodon.org/tags/GoPiGo3" class="mention hashtag" rel="nofollow noopener" target="_blank">#GoPiGo3</a> <a href="https://fosstodon.org/tags/Robots" class="mention hashtag" rel="nofollow noopener" target="_blank">#Robots</a> <a href="https://fosstodon.org/tags/charging" class="mention hashtag" rel="nofollow noopener" target="_blank">#charging</a>
