Design, Modeling and Control of a H-Frame Type XY Positioning System
XY positioning systems are widely used in industry to position a part or a tool within a two dimensional rectangular area. These systems are typically used for cutting, welding, marking or for pick-and-place applications. Current implementations of XY positioning systems typically consist of two linear guides, each with their own independent timing belts or ball/lead […]

Robotic Techniques for Securing and Removal of Caps from Bottles and Jars
The objective of this project is to investigate and develop robotic techniques for securing and removal of caps from bottles and jars through the use of custom-made sensor-equipped grippers. As a starting point, a robotic system was designed to both secure and remove the cap from a plastic bottle using force sensing resistors to register […]

Automation of a Brick-Joining Operation
The project addresses the development of a semi-automated system for the process of creating corner bricks which are made by joining two individual bricks. The corner bricks are used for exterior corners of buildings and window trims, and are made from two flat bricks cut at 45° angles such that they form a right angle […]

Automated Removal of Screws from Laptops
Electronic waste (e-waste) is a growing concern in the world, as the number of electronics used in everyday life continues to increase while the lifespan of these electronics continues to shrink. Efficient methods that can handle e-waste in an automated non-destructive fashion have not been developed. Screws are a common fastener used on electronic […]

Small Fault Detection of Discrete-Time Nonlinear Uncertain Systems
This article investigates the problem of small fault detection (sFD) for discrete-time nonlinear systems with uncertain dynamics. The faults are considered to be “small” in the sense that the system trajectories in the faulty mode always remain close to those in the normal mode, and the magnitude of fault can be smaller than that of […]

A Low-cost Spectral Camera for Online Vegetation and Water Identification
In general, each material reflects a different percentage of electro-magnetic (EM) radiation in each wavelength. By plotting those values with respect to the wavelength, it is possible to obtain what is called the “reflectance” of the inspected material. The reflectance is unique for each material and constitutes what can be considered a sort of spectral […]
