Abstract: Aspects of the present disclosure relate to track layout identification techniques. As an example, a set of track segments may be arranged in a certain order to form a track. A variety of track segment types may be used to form the track, and different combinations of the track segments may yield a track having varying characteristics. In an example, each track segment may comprise of a shift register, which may provide information to a base track segment relating to the order of the track segments and the track segment types that comprise the track. In some examples, the base track segment may relay the information to a computing device. Accordingly, the information may be used to determine a track layout, which may in turn be used to provide, for example, the ability for someone else to reproduce the track configuration.

Abstract: Aspects of the present disclosure relate to magnetic robot calibration. As an example, a robot may engage in a calibration process based at least in part on data samples from a magnetometer. The robot may use the data samples to determine a reference point, with which the robot may process movement instructions accordingly. In some examples, a user device may be used to control the robot, and may comprise a magnetometer for determining a reference point similar to that of the robot. As a result, the user device may communicate with the robot using movement instructions that are based on the reference point determined at the user device, such that the robot may perform the movement instructions using the reference point determined at the robot.
