This week we are dedicating our weekly update to Paul.


“Paul made a significant and positive impact on my life during the summer of 2013.

Before coming to PVNet as an intern in 2013, I had participated in the Constitutional Rights Foundation program, Mock Trial, at Palos Verdes Peninsula High School and was considering pursuing a legal career with a minor in business.

During my internship in the PVNet aerial robotics program, Paul introduced interns to the world of Autodesk Inventor and led to the discovery of my previously unknown interest in engineering and the world of CAD. It was love at first sight.

Paul’s mentoring resulted in my decision to become an aerospace engineer and commitment to continue gaining knowledge and skill using Autodesk Inventor, to join the robotics team at my school as CAD Captain, and to be elected Robotics Team President for 2014-2015.

Thank you Paul for what you did for me and the other interns.” – Sam Gioia


Search and Rescue!

It was a satisfying fifth week of the Advanced Technology and Technology Management Internships as the interns finished gathering the flight data from Portuguese Bend.


PVNet Interns continued to work in the Portuguese Bend landslide area this week. To prepare an autonomous flight, the exact path and elevation must be created and uploaded to the UAV.

To obtain the highest resolution we program the UAVs to fly as low as possible. Because the contours of this terrain vary so wildly, land elevations are measured and programmed but tree height is difficult to estimate.


During one of several flights on Monday, the quad UAV did not have quite enough altitude and became caught in the top of a tree, providing interns with an excellent opportunity to conduct a search and rescue operation.

Thinking it rebounded off the tree, the interns trekked across the wide area looking for the copter. After some time searching through the wilderness, Jeff used the range finder to locate the quadcopter, which was found hanging in the branches of the tall tree. Luckily, the copter was undamaged except for a few minor scratches, and it survived to fly another day.

3Intern Raul Castrellon and Jeff from Cal UAS retrieve the multi-rotor after it met a local tree and became lodged during its flight. It was a very happy moment.

4Canopies, chairs, cold drinks, WOW!!! – Surveying and remote sensing operations never looked so fun as Interns observe the watch the multi-rotor collect data.

7Jeff performs a final check on the transmitter before take-off.

15Intern Sully Chen engineers a less-than-effective method of securing the canopy from the wind: notice the small rocks sitting on top of the large rock.




Led by intern project leads Ben Stout and Raul Castrellon, the remote-controlled grappler team has been tasked with an interesting challenge: design a remotely controlled claw that can pick up a variety of small objects.

Multiple AutoDesk Inventor CAD designs by Aaron Lin and Lawrence Goo have been presented to the team for review. One of the designs included 4 claws with gears and a linear actuator which is actually a piston which drives the claw to open and close. Another design proposed using a conventional claw with threaded screw powered by a servo. Similar to arcade games that use claws to pick up a prize, the servo is remotely controlled by an operator while the UAV is controlled by a flight operator. Rumor has it a third design is in the works with improved claws.…more on that next week.

Parts have been ordered!

The video production team began watching training videos to learn how to operate Avid. Avid is considered to be the standard of the professional movie and television industry and provides complete work flow for complex projects requiring more than one person to perform editing and production. The video interns will spend a lot of time using Avid to create their hour-long video documentary about the internship. The team is comprised of Alyssa Oda, Eric Koshimizu, Jo Anna Edmison, Maggie Chen, Tia Kerkhof, and Toshi Shimizu.

11Interns Claire Bogosian and Barkha Scherp study the map of the area being surveyed.

12High school interns are fortunate to have college mentors like Max McHugh, shown here leading the 3D printer modification subproject team.


Summer Advanced Technology Internship Full – High school and college students will build the base of their own UAV quadcopter to record geographical aerial images and GPS data for the city of RPV. The course ends August 22nd.

 3D Animation Level 1 – This course is a unique creative opportunity in which industry professionals teach animation software to school-age students. The class takes place August 4th to August 27th from 9AM to 12PM




Education through Community Service

Since its founding in 1995, Palos Verdes on the Net (PVNet) has dedicated itself to community service through technology education and training. The non-profit’s public internet training seminars in 1995 had a profound impact on Palos Verdes Peninsula and its neighboring cities. Since then more than 75,000 adults have received technological training and over 4,000 students have come through the program at no cost. PVNet also has a long history of providing grants through their technology outreach program. Students receive class credit through Palos Verdes High School and Palos Verdes Peninsula High School.

But best of all, we achieve our goal of providing a unique type of learning opportunity which results in a quantifiable benefit to our community.

– Ted Vegvari, Founder, PVNet


Special thanks to the City of Rancho Palos Verdes for making this program possible for the past 20 years.
