Old projects

This is a list in reverse-chronological order of old projects I did before entering grad school.

Automatic Pneumonia Detection

I worked on the automatic detection of pneumonia through ultrasound image processing acquired by a Sonix RP system. The project was targeted towards screening applications. Pneumonia is a disease that largely affects children in Peru. I designed and implemented the algorithm and was the first author of a publication that was coauthored by the large team of technicians that helped gathering the data. This was published at the conference of the IEEE Engineering in Medicine and Biology Society.

Desktop Office Robots

I worked on a multidisciplinary project that studied the inclusion of service robots in office workspaces; more specifically, the design and implementation of a desktop robot. We used 3D printing for the prototype and published a paper at the International Conference on Social Robotics.

A Hand Tracking Solution

This project was part of my undergraduate thesis work. I proposed a practical solution to two hand tracking problems: the mutual occlusion between hands and the recovery from a lost tracking. The solution was deterministic and alternated the use of global and local information about past hand locations without the need of any hard-coded initial calibration. This was published as a proceeding of the IEEE Latin American Symposium on Circuits and Systems.

Automatic Machine for the Preparation of Sputum Samples

I am the coinventor of a medical device that was created to automatically perform the Ziehl-Neelsen staining process for Tuberculosis sputum samples. Before our project, the entire staining process was carried out manually. This device won the Peruvian National Contest of Inventions (Spanish links here and here) and was patented. I also presented an improved version of this invention at the “42nd International Exhibition of Inventions of Geneva”, Switzerland (Spanish link here).

Towards a 3D Reconstruction System in Mobile Devices for Telemedicine

This project won a funding contest for undergraduate research projects. At that time, there was the idea of using telemedicine for the treatment of Leishmaniasis in remote and poor areas in Peru. Surprisingly, 3D reconstruction of Leishmaniasis wounds showed promising results for its diagnosis, and my project was an initial step towards the implementation of this algorithm on a tablet device.

Jicamarca Acquisition Radar System (JARS)

During my internship at the Jicamarca Radio Observatory, I enhanced the performance of a digital receiver. I had to increase the transmission speed of data obtained from the acquisition channels of its receiver boards. The work involved hardware testing, electronic modifications, as well as strong VHDL coding. I coauthored an institutional poster with the full specs of this acquisition radar system, which can be found here .

Simple Walker Robot

This is my first robot which was built back in 2010. It is a walking robot made from the ground up and which uses two servos to move two pairs of rigid legs. Due to a simple mechanism and servo control, it was able to walk forward and turn both sides on flat surfaces. The robot can walk autonomously, but also follow user directional commands through signals of laser beams.
