The robotic head houses a mission control computer of the robot, a sensor package, and a radio communication module. The mission control computer comes as either a regular computer or a computer with a GPGPU-capable processor that enables massively parallel computations using OpenCL technology. The massively parallel computer is required if a high degree of autonomy of the robot is one of the mission profile requirements.
The robotic head can be installed directly on the turret servo of the chassis, or mounted on the top of a multi-segment robotic arm manipulator. A robotic gripper can be also mounted below the robotic head.
The mobile robot is designed with visual inspection application in mind. The robot is capable of raising its sensor head high enough to look inside automobiles with high ground clearance or into windows of buildings. The robot uniquely combines back-pack transportability and stairs climbing with a capability to look inside and under parked cars. This combination of capabilities is a key enabler for various public safety applications.
The robotic heads are optimized for the following control applications:
- Outdoor Mobile Robots
- Service Robots
- Robotic Arms for Mobile Robots
Since the robotic heads combine a high-performance computer and a set of sensors in the same package, the amount of cabling is significantly reduced, installation simplified and maintenance streamlined. The robotic heads can be also taken off the robots and used as desktop testbed computers by developers of onboard software; an HDMI monitor port and a keyboard port are provided to simplify desktop-style use.
The robotic heads come with watertight sockets for connecting external payloads such as Servosila Servo Drives or a Thermal Vision Camera. The external payloads are controlled via CAN, Ethernet or USB onboard buses, and powered by a payload power supply line, - via the same watertight socket.

Software-Defined Functions of the Robotic Head
The hardware configuration of the robotic head is specifically designed for the following tasks (depending on installed software):
- Remote control of a mobile robot with onboard video compression and streaming
- Controlling multiple servo drives, differential drive motors and other actuators, health checks and monitoring of servo drives via a CAN bus
- Automatic obstacle detection and avoidance using a laser scanner or/and a stereo vision system
- Visual object recognition, visual localization, and visual object tracking using multiple video cameras
- Simultaneous Localization and Mapping (SLAM) via fusion and filtering of data coming from multiple sensors including a laser scanner, a stereo vision, a MEMS inertial measurement unit and a GPS/GLONASS receiver
- Path planning using a digital map created via a SLAM method
- Robotic arm control including inverse kinematics and 3D motion planning
- Automatic self-leveling of a mobile robot
- Self-Health Testing.
