Interesting 3D Printed Robotics Projects for Students
Complex designs, expensive costs, or confusing starting points can make many educators and students feel overwhelmed when trying to combine 3D printing with robotics. As a result, ideas may stagnate and chances to learn may pass you by.
Students might become disengaged or not understand the relevance of their skills in the absence of practical examples. Realizing you have untapped potential but lack the proper direction is incredibly frustrating. Here are a few of the most jaw-dropping 3D-printed robotics creations spearheaded by students from all across the globe.
1. Cobra: Lunar Snakebot by Northeastern University

Emerging engineers from Northeastern University created the bio-inspired snake robot Cobra. Its principal function is to traverse rough surfaces, like those on the moon. The eleven articulated parts of the robot enable it to move like a genuine snake, including slithering across the sand and bending into a wheel shape to roll down steep slopes. The robot remains lightweight while being robust, thanks to its carbon-fiber components and 3D-printed joints.
Cobra, operated by a Raspberry Pi, provides space for research payloads, such as a neutron spectrometer to detect water ice on the moon. As part of NASA's BIG Idea Challenge, the students created this robot and put it through its paces in a desert environment meant to mimic the moon. Students gained knowledge in mechanical linkage, modular design, space robotics, and autonomous navigation in low-gravity, rough-terrain situations through this project.

University of Virginia students created Wendy, an autonomous plane. The sturdy polymer parts that make up its 3D printing process allow it a wingspan of about 6.5 feet. The goal of the project was to demonstrate that large-scale UAVs could be efficiently and cheaply built utilizing additive manufacturing. The standout feature is the use of a regular Android smartphone for piloting Wendy. This smartphone takes care of the autopilot software, camera features, and GPS.
The students created and tested Wendy's parts using rapid prototyping methods. They re-engineered and 3D-printed a new set of landing gear in just 24 hours after the first set snapped during testing. Students learnt a great deal about design resilience, flight mechanics, and sensor-driven navigation through this iterative method. As an example of how simple, readily available resources may drive complicated systems, the project highlighted the integration of robotics hardware with mobile devices.

The robotics club at Lyndon B. Johnson High School in Laredo, Texas, built a hydroponic gardening system powered by 3D-printed parts. A motorized irrigation rig is part of the system, and it can irrigate 84 separate plants in a vertical garden configuration. We used the school's 3D printers to create the whole gear system and digitally modeled the frame. The control system automates the flow and monitors water levels using basic sensors and Arduino microcontrollers.
This project addressed both engineering and environmental concerns. Sustainable agriculture, robotics, fluid dynamics, and DFM were among the topics covered. Using CAD models, gear ratio calculations, and code, more than 27 students worked together on the project. A practical indoor garden for campus vegetable production was the end result. It also pioneered the idea of "green" robotics, combining environmental science with automation for practical applications.

Hendersonville High School students in Tennessee collaborated on a groundbreaking initiative to create a robotic prosthetic hand for Sergio Peralta, a fellow student who was born with a deformity in his right hand. The students spent four weeks modeling a unique prosthetic hand in Fusion 360. After 3D printing, they assembled it using inexpensive materials such as PLA filament, common screws, and elastic cords for the joints.
The prosthetic hand gave Sergio the ability to do things he had never done before, like pick up an object or catch a ball. In addition to fostering empathy and teamwork, this initiative educated students in biomechanics, prosthesis design, and 3D modeling. For the creators and the receiver, it was a very moving and fulfilling event. By combining student-led robotics with open-source technologies and a mission-driven mindset, the project demonstrated the societal potential of these approaches.
5. University of Arizona Hexapod Robot
Read full story: wired.
Researchers and students at the University of Arizona constructed a hexapod, a type of walking robot with six legs. The 3D printing of structural parts and leg joints enabled the creation of this massive robot. It moves like an insect thanks to its movable legs. The robot has several sensors, such as a vision system, an Intel Edison processor, and long-range radar (LIDAR). You may program it to recognize objects and plan routes using a touchscreen tablet.
The hexapod is a great way for students to learn about intricate leg mobility and for researchers to conduct their own experiments. Mechanical design, navigational software, and gait control were among the many areas covered by the students. Students learnt complex robotics, perception, and kinematics techniques while putting the robot through its paces in an environmental mapping and computer vision lab.
6. Utah Valley University 3D-Printed Hexapod
Read full story: Aseepeer.
Students from Utah Valley University created a hexapod robot using 3D printing technology. They intend to utilize it for robotics classes and experiments. A 3D-printed chassis, servo-driven legs, and bespoke PCB boards provide the power and control for this diminutive robot. The students made the robot controllable from a laptop or smartphone by integrating wireless connection devices. In addition to being able to move forward, turn, and traverse basic terrain, the hexapod had pre-set gaits.
The ASEE conference featured the project as an example of student design. Topics covered included algorithmic movement, sensor fusion, and embedded systems programming. To keep costs down and facilitate student experimentation, the project's designers prioritized modularity and encouraged teams to build upon existing, open-source models.
7. Reddit Lockdown Hexapod Project

In the midst of the COVID-19 quarantines, a do-it-yourself student constructed a hexapod robot. The student manufactured the chassis, servo housings, and all six legs using FreeCAD and a regular FDM 3D printer. For a better grip, the feet were lined with TPU rubber. Preliminary testing of the robot's motion was conducted in a 3D OpenGL simulator, and it is Bluetooth-controlled by a purpose-built mobile app.
The builders educated themselves on robotics, electronics, and remote control systems, and built the robot from the ground up. Students can participate in high-level robotics projects using free and open-source tools even without formal lab access; they recorded their build process to help others.
8. HOPPY: Legged Robot for Dynamic Motion
Read full story: Illinois.
Students in their first year of college at the University of Illinois use HOPPY, a manipulative hopping robot. Designed to be stable during controlled horizontal movement, it rests atop a gantry. The students learn about compliance, leg mechanics, and real-time control as they print and build the robot. HOPPY has accomplished a remarkable feat in dynamic legged movement by maintaining balance while reaching speeds above 1.7 m/s.
Students conduct experiments to determine the effects of various control algorithms on running and jumping as part of a course requirement. Tuning PID controllers is part of their physics-based simulation work. Pupils will be ready for more complex robotics projects with real-time system feedback and dynamic stability as they complete this one.
9. DeltaZ: 3D-Printed Delta Robot
Read full story: Arxiv.
The three-armed, delta-shaped robot DeltaZ was 3D printed. Students built it, and it can do exact positioning tasks quickly. DeltaZ is great for light object manipulation or writing since it combines hard and soft components for structure and compliance. Control theory and inverse kinematics are two topics that frequently make use of it in the classroom.
The pupils use an Arduino or Raspberry Pi to control the robot, which they build from pre-printed components. Students gain a better grasp of the differences between serial and parallel robotic arms, as well as a visual representation of spatial movement, through this project. Its modular structure permits more research into artificial intelligence-based control, such as reinforcement learning.
10. HeRo 2.0: Student Swarm Robotics Platform
