hardware and task classes for studying [[Has Research Topic::Depth Perception]] from [[Has Research Topic::Motion Parallax]]. This is (i think!) unpublished work with [[Involves Person::Phil Parker]] in the [[Involves Person::Cris Niell]] lab, so more details will be forthcoming! They recently published this task in [[Has DOI::https://doi.org/10.1101/2021.09.29.462468v1]] == Platform == The platform is an array of stepper motors connected to vertical pillars on linear actuating rods that extends the [[Extends Autopilot Class::hardware.Hardware|Hardware]] class to control them. More information can be found in its docstring, but in short: the platform works by latching a certain set of pillars as active, then the step and direction signals are shared by all of them. To simulate independent movement, the active pillar latches are strobed (smartly, after a 2-d height command is given, pillars are raised and lowered until they reach the closest value, then deactivated, and so on.). The platform has both a position and velocity mode, and the velocity mode is used in closed loop with an [[Uses Part::LSM9DS1]] IMU, along with the [[Uses Autopilot Class::transform.geometry.IMU_Orientation|IMU_Orientation transform]]. == Parallax == The [[Extends Autopilot Class::tasks.Task|task]] itself, which I don't think I can say too much about! Except that it uses a combination of the IMU and live tracking with [[Uses Autopilot Class::transform.image.DLC|DLC]] ([[Uses Python Package::DeepLabCut]]) [[Uses Python Package::DeepLabCut-Live|live]] to make a very fast but accurate estimate of the position of the subject wearing the IMU!
