An Introduction to STEM ROV

STEM ROV targets elementary and junior high school students and has been promoted abroad for some time. Through affordable material and simple assembly, STEM ROV has helped popularize underwater robot enlightenment on campus.

STEM ROV aims to encourage students to assemble their desired ROV, and the assembly process helps students learn about underwater robots and the related principles. After the assembly is completed, students can enjoy and operate their ROV artifact in safe waters such as swimming pools.


Considering simple assembly and low cost, STEM ROVs generally use plastic water pipes for the body, allowing students to assemble ROVs of various shapes. As for thruster design, brush motors are generally used as the propelling power source. In terms of waterproofing, the easy-to-obtain film box and butter are the solutions. For the control system, there are various circuit boards to control the operation of brush motor through the CATE5E network cable. For power system, a 12V locomotive battery is generally used for power supply. In addition to providing control, the CAT5E cable also provides power from battery for the brush motor.



Ohm’s law and Archimedes’ principle are also quite helpful for STEM ROV courses. The former can help optimize STEAM ROV thrust performance while the latter can fine tune ROV’s movement postures such as diving / rising in the water.



ROV MAKER will share relevant experiences and thoughts about the correlation of STEM ROV and the development of Ipanema ROV Kit. The thoughts are classified into the following topics.

  • Frame & buoyancy
  • Simple Thruster and its waterproofing
  • STEM ROV control
  • Power supply
  • Underwater imaging module

These topics will be introduced in separate articles. For those interested in the articles, please register yourself as a member of the ROVMAKER website to get the notice of the article publication.
