Robotis OP3

Robotis OP3: at last, a humanoid robot that’s superb value for money

Not everyone can afford a humanoid robot, far from it, because the electronics and mechanics involved are particularly complex. But Robotis has now brought us an updated version of its humanoid robot at a truly attractive price, ideal for universities of science and technology, research labs and manufacturers.

Robotis OP3 is a miniature humanoid, standing just 51 cm tall, that’s open-source programmable on Linux, has 20 degrees of freedom, one main dual-core processor and a secondary ARM Cortex-M7 processor. It has an autonomous, IMU navigation system that uses three instruments: a 3-axis gyroscope, magnetometer and accelerometer. The IMU allows you to configure and analyse its rotation speed, acceleration and even direction. Robotis OP3 has an embedded, high-definition webcam offering a 1920 x 1080-pixel resolution allowing it to interact in numerous ways with its environment, for example by detecting colours and shapes and using facial recognition.

The OP3 robot by Robotis: more memory, more powerful

If you’ve already played with the OP2, you’ll know it performs impressively well. Well the OP3 takes things up a notch:

• A more powerful processor, equipped with a replaceable SDRAM that’s four times greater
• A memory storage module that’s also four times larger
• A higher definition camera
• Ethernet and Bluetooth 4.1 connectivity (the OP2 offered just an Ethernet connection)
• Supports all 32-bit AND 64-bit versions of Windows and Linux, etc.

In short, you’ll find everything you’ve always loved about the OP2 Robotis humanoid in the OP3... only better!
