Reachy's head specifications

Reachy’s head features two cameras: one to observe its environment and another camera to focus on the task of manipulating. The head is animated by Orbita, a unique technology developed by Pollen Robotics’ R&D team. This ball joint actuator allows unpreceded dynamic and multi-directional movement. With animated antennas, Reachy can convey many emotions to his audience.

2 Raspberry Pi cameras associated with 2 optical lenses (one macro and one wide angle). See details on Raspberry Pi Camera module here: https://www.raspberrypi.org/documentation/hardware/camera/

Orbita neck joint

Ball joint actuator that is composed of a parallel mechanism motorized by 3 DC Maxon motors. The control of each motor is done with a Pololu magnetic encoder and an LUOS DC motor module.


Antennas are animated by a Dynamixel motor and are removable. A system of 3 magnets (2 south and 1 north) allow to attach the antennas to the rotation axis.
