GEKKO is an educational suite that includes a robot arm kit (GK-RA) and e-learning software (GEKKO app).
GEKKO app is a streamlined educational journey that helps users build, program and pilot their own robot arm. Step-by-step, without any need for prior knowledge or experience. If you ever wondered where to start with robotics — start with GEKKO.
< This is GK-RA, an educational articulated robot arm that fits on your table. GK-RA is what you are going to build and program.

GK-RA uses MakerBase Servo42 as the encoder and primary driver for stepper motors, making GK-RA a closed-loop system.
To ensure user-friendliness, GEKKO is developed using an Arduino microcontroller (Arduino MEGA 2560).
This is GEKKO app.
It contains all educational material and exercises with the primary goal of helping you build and program your own robot arm. GEKKO app assumes no prior knowledge or experience with robotics or programming and will teach you every step of the way — from assembly to programming your own control system using Arduino and C++.
Along the way, you will learn concepts such as inverse kinematics and the working principles of electric motors and microcontrollers.
The whole journey is divided into chapters, each covering a specific development stage.
This study program revolves around GK-RA and constant interactions with the robot. GK-RA is your primary practice tool and the main medium for the exercises provided by the GEKKO app.
> GK-RA 1.0 has been assembled and tested.
> A new joint design was developed around space and mass efficiency — the GK-RA body can now be “folded” into a compact power-off resting position, which also works as a start-up reference point for the encoders. Torque requirements are now significantly lower, making GK-RA 1.0 a lot faster.
> Proto-GK-RA model was successfully stress-tested by engineering students.
> The robot was included as one of the week-long challenges for the students during the TCB international event at SAMK campus in Pori, Finland. During the event, students had to program the robot to perform a pick-and-place task using their own ideas for gripper and conveyor belt designs.
> GK-RA 0.0 (Proto-GK-RA) has been assembled and tested.
< Current milestones and general state of development.
GEKKO started its journey in August 2025 and is still in active development. Subscribe to the mailing list to stay updated.

Students from Europe were able to test and program the Proto-GK-RA model during the international TCB week at SAMK.
Elative Systems is a young start-up from Finland. We design and develop non-intrusive robotic products and solutions.
Our first product, the educational platform GEKKO, is preparing for a crowdfunding campaign launch. Support of the campaign is crucial for the project’s future, and we welcome any feedback, suggestions or simple letters to say “Hi”.
We are always looking for cooperation and support opportunities. Feel free to contact us.
The GK-RA design, the content of the e-learning software and its user interface are subject to change. GEKKO is still in development; displayed imagery does not represent the end product.
