To precisely and reproducibly position test objects within the saline tank a position controller was constructed from standard LEGO parts in connection with a set of motors and two controllers (LEGO NXT Mindstorm). Two test objects could be positioned independently by a total of six position controllers, two for each of the X, Y and Z directions. In order to overcome the limitations in the range of motion imposed by the physical size of the LEGO parts the entire control unit rotates 360° on a plastic support placed on top of a cylindrical tank. The movement protocol was stored on a computer and transmitted to the position controllers via Bluetooth. A control program stores the coordinates and the position controller automatically moves the object to the desired locations.
Original work was done in 2009 by Sascha Reidt in Landquart, Switzerland. In 2012, Jonathan From updated the software, tests and documentation.

For the position
controller, we have to set parameters based on target volume type, single or
double objects, specific positions and PC port number to establish a connection
between a PC and the controller (a separate tutorial is provided on EIDORS
website on how to operate it). The position controller moves the target to the
specified position and gives an indication to the user to take EIT measurement
after certain delay for each protocol.
