Robotnik, a Spanish company specialized in robot product development and robotics R&D
services, has developed its new mobile manipulator called RB-1.
RB-1 is a mobile manipulator designed with extensibility and modularity for research and
application customization. The robot has been designed using a single type of the Korean
manufacturer ROBOTIS actuators and corresponding with the product range Dynamixel PRO.
The Dynamixel PRO servo-actuators integrate controller and servo-amplifier inside the
actuator housing, simplifying its interconnection to 2 supply wires and 2 additional wires for a
The arm has an anthropomorphic configuration of 7 DOF plus 1 DOF to elevate the torso and
one gripper. All actuators are attached directly to the element holders with the exception of
the second wrist axis, which transmits its torque by means of a pulley. This allows to increase
the payload but at the same time to increase the manipulability index.
Regarding sensors, RB-1 mounts a Hokuyo URG-04LX-UG01 laser, a 2D laser range finder for navigation, localization and gyro board, and a 2DOF pan-tilt unit for the environment
perception by means of a Microsoft Kinect/ASUS Xtion PRO Live RGBD Sensor, to recognize
objects in the environment, but also for navigation and localization purposes.
Another advantage of RB-1 is that has completely open-source software, ROS, so everyone can contribute by uploading their own modules for development and programming.
RB-1 is conceived to R&D applications, AAL (Ambient Assisted Living), indoor mobile
manipulation or remote handling, among others.
RB-1 has different configurations, the complete configuration of 13 DOF has a price of 46.200€, the version which has an arm of 6 DOF is around 44.000€. The mobile base platform can also be ordered separately for 12.500€.
