A nice project to test the newly available Open-Cube sensor – a laser rangefinder based on the “U85B” module extracted from the commercial handheld Asist LM030. The sensor uses a red visible point laser, so it is very suitable for some maze mapping tasks, for example, because it is not blocked by nearby objects like …

Open-Cube controllers and sensors were used in ROBOTs teaching in the winter semester 2024/2025 at the Czech Technical University in Prague, Faculty of Electrical Engineering. ROBOTs is a motivational course for students of the Cybernetics and Robotics study program (first semester). It turned out to be quite suitable for teaching. Massive use helped to find …
A fun project in the class of robots… (CTU in Prague, FEE, Cybernetics and Robotics) Open-Cube control unit with NXT motor and EV3 ultrasonic sensor / O-C Lidar sensor…
Nice toy to play with… uses internal gyroscope and accelerometer, see description below. Segway is a robot that balances on two wheels using data obtained from an integrated IMU (three-axis gyroscope and accelerometer). The tilt angle with respect to the horizontal axis of the robot is determined by fusing the gyroscope and accelerometer data using …
LEGO compatible motors are quite difficult to make from basic parts. You need a suitable DC motor, a quadrature encoder, some gears and a housing.. it’s not impossible, but it’s much easier to buy something from Aliexpress… We ordered some “large servo motors” that claim to be EV3 compatible from Aliexpress (seller “A Toy A …

Well, it took some time and a lot of effort, but we finally finished making the first 25 pieces. In this post, we’ll share a few production notes as well as plenty of pictures to document it. We ordered the soldering at AllPCB as we had a good previous experience and they are probably more …
At the beginning of September, we put the first batch of the second version of the Open-Cube into production in China, along with two of our own sensor designs. 25 Open-cubes, 50 optical reflective RGB sensors and 30 LIDAR distance sensors should be produced. During the manufacturing, the company asked to confirm the pick-and-place file …
