Establishing a cost effective control and robotics program: Delay based wireless feedback control using LEGO's

As part of a series of papers that explore the extent to which LEGO kits can be used to introduce important control system and robotics concepts to both undergraduate and graduate engineering students, this paper attempts to build a delay based wireless control system using LEGO kits. The paper introduces a method that takes into account the delay that gets added due to switching from wired communication to wireless. By replacing the wire with a wireless connection, the system becomes a wireless control system (WCS). The impact of delay on the wireless control system is observed. The control effort required before and after delay is compared.
