Matthew Hammer

Chief Operations Officer

Matt is an experienced Droid builder and founder of the Hampton Roads Droid Builders.  Matt is also the Chief Operations Officer of the TSJ Foundation. Matt has training as a biomedical equipment technician and grew up building boats and computers with his father. He retired from the army due to wounds sustained in Iraq and found droid building in 2010 and built several r series (R2) and founded the Hampton Roads R2 Builder’s club. For years it was just him and would do events on his own until the release of the force awakens and BB-8.  The renewal of interest had others seek out an join the club and he changed the name to the Hampton Roads Droid Builders to incorporate all the different droids; his main area of expertise is the R series but have been doing a lot of work with BB-8. He help built the Foundation’s fully functional BB-8 unit.  He is currently building the R2 unit for the I-ARTS program. This R2 unit will have an extra new programming station with several different Arduino based systems.  With R2 we can teach not only electrical but mechanical and optical we are planning to use a projection system to teach kids how it works. With so many different control systems including I2c, Bluetooth Wi-Fi the communications between mechanical and electrical are really well refined and for kids, watching somethings start as an electron a command and end as a physical robotic command is amazing.  R2 D2 can be a basic robot or an extremely advanced, something as simple as a 3200 chip to control or to a fully functional desktop computer inside for complex response and all interactive.

David Ferreira

David has been involved in the competitive robotic world since 1996. During that time, David was able to learn and practice the skills of engineering science and technology. The robot was just a tool that brought people together. The true goal of the programs was to inspire the next generation of innovators.

Today David looks to inspire by bridging the gap between all age groups and physical abilities. (We all have a love of Star Wars, so let us show the world how it’s done) This has been the basis for his projects in recent years.

David had designed and created fully functional BB-8 units that can Interact with the public like no other. Seeing the joy and happiness BB-8 brings to the public has driven him to make more exciting droids to inspire the next generation.

Most recently David has contributed to some of the droids on the Boba Fett series and you may have seen his droid on the Star Wars Show, “Gil” RX-91L. David is also one of the TSJ Foundation full time builders and he is designing and building many of the STEAM educational programs.

Jon Haag

Jon has been a lover of all things Star Wars throughout his life. Having been a member of the 501st Legion since 2016, he branched out into droid building in 2017 after attending Star Wars Celebration Orlando and seeing the many the droids on display there. Jon is heavily focused on leveraging 3D printing in the build process, having completed two iterations of his fully 3D-printed C2-B5 (the Imperial R-series droid briefly seen in Rogue One) and completed one of the latest droids in the Star Wars universe: D-0 from Episode IX. He has also built a DO for the TSJ Foundation I-ARTS program.

Jon currently serves as one of the lead members of the Hampton Roads Droid Builders, with a focus on public relations and event coordination.

Tim O’ Sullivan

Tim OSullivan is a retired military officer with 21 years of active-duty service. Tim was medically retired in 2013 for combat wounds sustained in Basra Iraq. Upon retiring from his military service he later found the therapeutic tasks of 3D printing, 3D modeling building Droids and movie related props. Tims award winning cosplay characters have placed in both San Diego Comicon and Star Wars Celebration. His builds and animatronics have since been used to support to STEAM programs, Children Hospitals, Veteran Events and Service Dog organizations. His work had also enabled him to 3D model and develop a special prosthetic that was used for a child in the Paralympics. Over the past 5 years Tims builds include C-3PO, Bistan Moroff, R2D2, BB-8, DO, Chopper, Q9-0, Life size Taun Taun bust, Animatronic Babu Frick, Animatronic Episode 1 C-3PO, Animatronic Rat Catcher bust, Animatronic Grogu and most recently earned 2nd place in 2022 Star Wars Celebration Cosplay competition in Anaheim as Bistan from Rogue One. Tim is currently building animatronic Grogu, C-3P0, Argus and Babu Frick for the TSJ Foundation Educational STEAM programs.

Dr. Joshua Montgomery

Dr. Joshua Montgomery is a Computer Science Professor at Southern State Community College & Adjunct Instructor at Southern New Hampshire University. Montgomery has been a professor for over 10 years, and before that was the Technology Director for the Chillicothe City Schools for 13 years. He is the Curriculum Coordinator for the Ohio Coders Project, an initiative that was developed by the state of Ohio to help K-12 schools in the southern region of the state to develop coding programs and skills for students. Montgomery is the cofounder of SOMACC (Southern Ohio Makers Against COVID Coalition). This grassroots group built 4,500 3D-printed face shields for first responders at the start of the COVID-19 pandemic. He is the inventor of the Droid Builders Mini-Dome, a teaching tool used to instruct students in electronics and coding by using a 50% scaled 3D printed R2-D2 dome that can be programmed to blink lights, move motors and play sounds. This project is now supported, funded and powered by the Grant Imahara Foundation.

The Grant Imahara Foundation has purchased supplies and materials for 102 students to build 72 domes for the 2021/2022 school year so students can complete the Grant Imahara Coding Challenge. This coding challenge is a supported initiative by the Ohio Coders Project and will help to further those students understanding of both electronics and coding. Montgomery is also an active member of the Star Wars builder communities.
One of his most significant accomplishments is building a replica of R2-D2, a droid from the movie Star Wars that took him 2.5 years to complete. Montgomery used that experience of building R2-D2 to change how he teaches classes at his college. He explained how building R2-D2 made him a better teacher in his Ted Talk at Dayton Ohio in 2021. Josh and his wife, Brandy, reside in Southern Ohio with their two children and 4 dogs.

Martin Cerame Colón

Martín Cerame Colón
A creative mind that has explored multiple forms of expression, from orchestral composition to digital graphic design, Martin has been an avid fan of science fiction and fantasy ever since he saw Star Wars in 1977. He had the fortune of being able to transfer his drawing skills from paper to screen when his father bought a Macintosh computer back in the 1980’s and allowed Martín to use it and develop his skills as a digital graphic artist as the technology evolved.

Throughout the years, Martín grew professionally as both a graphic designer and a performing and recording musician. His passion for Star Wars drove him to design set maquettes for his 3-3/4” action figures during the 90’s; maquettes that he could not get built at the time because the access to computer-controlled tools like CNC machines and laser cutters was very limited at the time.

It would take 30 years for the necessary technology to become affordable for hobbyists like Martín, who acquired his first desktop laser cutter during early 2022 and began constructing control panels based on those featured in the Star Wars films. With a keen eye for the visual language of Star Wars, Martín’s designs quickly earned the praise and respect of fellow and more experienced builders like Brian Thompson, creator of the Smugglers Room channel on YouTube and the Star Wars Room Builders Group on Facebook, who featured Martín’s work (along with other builders’) in an episode titled “Secrets of Star Wars Design”.

Martín continues to build control panels and props combining laser cut and engraved acrylic with LED elements and display screens, all of which can be seen in his Facebook and Instagram pages under the name Dune Sea Outpost.

Andrew Wood

Nicole Ortuno

I am currently a high school senior passionate about robotics and mechatronics engineering. In the future I wish to specialize in humanoid robots and pursue a career as a robotics business leader. I wish to achieve beyond just a STEM career, major, I am excited to explore the diverse communities that are rich in networking and connect with communities all over the world. I love to learn and expand my knowledge in various areas that advance my understanding of the world. 

    I have had the opportunity to conduct research alongside a computer professor at George Mason University where we developed a robot path planning optimization program based on partially known areas and built behavior-correcting algorithm for robot interpretation. While I have continued to connect with professionals in the robotics field, this past summer I worked alongside a professor at Carnegie Mellon University whose focuses on actuation and legged dynamic controls. Our research proposed an alternative feedback system that favors force control to develop “squishy”-like robotics structures, analyzing the most advanced humanoid robots built in companies such as Boston Dynamics. 

    In addition to my efforts in working alongside field professionals, I have also founded the RoVersity Project, an introductory robotics program to engage a group of young elementary students at a local homeless shelter. Through STEM summer programs and competition experience, students explore their interests and further their knowledge in STEM that captivate their curious minds. With the support of tech companies such as Amazon and UBTech as well as partnering organizations including George Mason University, we have supported our students with milestone opportunities for them to receive a final collegiate scholarship to continue their education as first generation students. 

    I am dedicated and passionate about breaking down barriers for women and underrepresented minorities in STEM careers. I am excited to be apart of such a rewarding organization and build animatronics that will inspire confidence among young students in finding their passions.
