In my previous story, I discussed how a simple program can be written to monitor Anki Vector 24x7. Many of the discussions in social media about the story seemed centered around Vector’s battery performance. Indeed, battery life is an essential ingredient of a robot, and by extension, for Internet of Things (IoT) devices. A mobile robot needs a battery, and can be active only as long as it retains battery power. Given the high interest in how Vector’s battery performs, we thought that it was document an unbiased third party investigation. Moreover, since the Vector is representative of a full-scale industrial robot, it is a great candidate for evaluation of the current state of battery technologies in robotics. In this article, we compare the battery voltage drain rate as a function of time for two of Anki robots, the Anki Vector, first released in October 2018, and Anki Cozmo, first released in October 2016.
