How to get to us
Cardiovascular failure is the most frequent death cause in Germany. In Bavaria, about 60.000 persons die annually on the cause of cardiovascular diseases, this corresponds to approx. 50% of all deaths. A possibility of treatment is the implantation of ventricular assist devices. Those " Artificial hearts " should not be, in this connection, an entire substitute with the natural organ.
Numerous simple command tasks in telerobotics and telepresence can be accomplished with human machine interfaces with a maximum of two or three degrees of freedom (DoF). For this kind of applications the joystick represents a very intuitive way to command a teleoperator or an object within a virtual environment in two DoF.
Miniature Force-Torque Sensor
The miniature six-component force/torque sensor with full digital output has been developed for the fingertip of the new generation dexterous robot hand DLR Hand-II.
The well-known SpaceMouse was developed out of a space application from the DLR in the 1990s. Here you can read our first steps in the development of this unique control device.
The mechatronic goals
Our approach in designing a new generation of multisensory light-weight robots is an integral one. To be more specific: the new sensor and actuator generations developed in the last years do not only show up a high degree of electronic and processor integration, but also a fully modular hard- and software structure. Analog conditioning, power supply and digital preprocessing are typical subsystem modules of this kind.
Light-weight actuator and drive systems
Both the DLR-gripper and the joint drives of our light-weight robot make use of the same motor concept based on our own redesign of commercially available two-phase stepping motors of the ESCAP type. These motors were basically attractive for our light-weight goals because they show up
