First Steps for Hector the Robot Stick Insect
A research team at Bielefeld University has succeeded in teaching the only robot of its kind in the world how to walk. Its first steps have been recorded in a video. You can watch them in Bielefeld University's latest posting on 'research_tv'. The robot is called Hector, and its construction is modelled on a stick insect. Inspired by the insect, Hector has passive elastic joints and an ultralight exoskeleton. What makes it unique is that it is also equipped with a great number of sensors and it functions according to a biologically inspired decentralized reactive control concept: the Walknet. By 2017, the walking robot will be equipped with additional abilities in a major project at the Center of Excellence Cognitive Interaction Technology (CITEC).

The walking robot has been built by the Biomechatronics research group. In the future, Hector should serve as a platform for biologists and roboticists to test hypotheses about animal locomotion. One major aspect will be the fusion of large amounts of data from sensors so that the robot can walk more autonomously than before. A further key issue will be the optimal coordination of movements by a robot with elastic drives.
'The way that the elasticity in Hector's drives acts is comparable to the way that muscles act in biological systems,' says Professor Dr. Axel Schneider. He is heading the Biomechatronics research group and is coordinating the CITEC project together with Professor Dr. Volker Dürr from the Department of Biological Cybernetics at the Faculty of Biology. Schneider and his team developed the elastic joint drives themselves. Hector has 18 such joints. Through the biologically inspired elasticity of the drives, Hector can adapt flexibly to the properties of the surfaces over which it is walking.
'However, elasticity alone is not enough for Hector to be able to walk through a natural environment containing obstacles,' says Schneider. 'The challenge was to develop a control system that would coordinate the movements of its legs in difficult surroundings as well.' Schneider's colleague Jan Paskarbeit was responsible for developing and building the robot. He also programmed a virtual version of Hector in order to test experimental control approaches without damaging the robot. 'All sub-systems have to communicate with each other for the robot to walk without any difficulties,' says Paskarbeit. 'Otherwise, for example, Hector might have too many legs in the air at one time, become unstable, and fall over. Moreover, the legs have to be able to react to collisions with obstacles. We have dealt with this by implementing a reflex behaviour for climbing over objects,' explains the CITEC researcher.
At the CITEC Center of Excellence, eight research groups have joined together for three years in a large-scale project to optimize Hector. The scientists come from the fields of computer science, biology, physics, and engineering. Currently, the researchers are working on equipping Hector's front section with far-range sensors as in a head. They already have a prototype with two lateral cameras and two tactile feelers. Both the visual and the tactile systems are inpired by those of insects - their work spaces and their resolutions are similar to those of animal models. 'A major challenge will now be to find an efficient way to integrate these far-range sensors with the posture sensors and joint control sensors. Hector is the ideal research platform on which to do this,' says Volker Dürr.
The research on Hector is the outcome of a series of earlier research projects. For example, the functional parts for Hector were manufactured in the CITEC project 'MULERO' and in the project 'ELAN'. 'ELAN' was financed by the Federal Ministry of Education and Research. In the EU project 'EMICAB', Axel Schneider's and Volker Dürr's teams collaborated with three further European teams engaged in research on intelligent motion control in insects and robots. For Dürr and his team, this involved evaluating motion sequences in stick insects in order to understand the control mechanisms in the insect's nervous system and transfer these to computer models. A further stage in the construction of the robot was the design and manufacture of the robot body. A green and white design model was developed with designers from the Folkwang University of the Arts in Essen and engineers at the Leibniz Institute of Polymer Research in Dresden. The casing of the robot is now black, because it is made of carbon-fibre-reinforced plastic (CFRP) to save weight.
The CITEC Center of Excellence is spending 740,000 Euros on the current Hector major project entitled 'Embodied Interaction as a Core of Cognitive Interaction'.

/ About us
Founded by Russian entrepreneur Dmitry Itskov in February 2011 with the participation of leading Russian specialists in the field of neural interfaces, robotics, artificial organs and systems.
The main goals of the 2045 Initiative: the creation and realization of a new strategy for the development of humanity which meets global civilization challenges; the creation of optimale conditions promoting the spiritual enlightenment of humanity; and the realization of a new futuristic reality based on 5 principles: high spirituality, high culture, high ethics, high science and high technologies.
The main science mega-project of the 2045 Initiative aims to create technologies enabling the transfer of a individual’s personality to a more advanced non-biological carrier, and extending life, including to the point of immortality. We devote particular attention to enabling the fullest possible dialogue between the world’s major spiritual traditions, science and society.
A large-scale transformation of humanity, comparable to some of the major spiritual and sci-tech revolutions in history, will require a new strategy. We believe this to be necessary to overcome existing crises, which threaten our planetary habitat and the continued existence of humanity as a species. With the 2045 Initiative, we hope to realize a new strategy for humanity's development, and in so doing, create a more productive, fulfilling, and satisfying future.
The "2045" team is working towards creating an international research center where leading scientists will be engaged in research and development in the fields of anthropomorphic robotics, living systems modeling and brain and consciousness modeling with the goal of transferring one’s individual consciousness to an artificial carrier and achieving cybernetic immortality.
An annual congress "The Global Future 2045" is organized by the Initiative to give platform for discussing mankind's evolutionary strategy based on technologies of cybernetic immortality as well as the possible impact of such technologies on global society, politics and economies of the future.
Future prospects of "2045" Initiative for society
2015-2020
The emergence and widespread use of affordable android "avatars" controlled by a "brain-computer" interface. Coupled with related technologies “avatars’ will give people a number of new features: ability to work in dangerous environments, perform rescue operations, travel in extreme situations etc.
Avatar components will be used in medicine for the rehabilitation of fully or partially disabled patients giving them prosthetic limbs or recover lost senses.
2020-2025
Creation of an autonomous life-support system for the human brain linked to a robot, ‘avatar’, will save people whose body is completely worn out or irreversibly damaged. Any patient with an intact brain will be able to return to a fully functioning bodily life. Such technologies will greatly enlarge the possibility of hybrid bio-electronic devices, thus creating a new IT revolution and will make all kinds of superimpositions of electronic and biological systems possible.
2030-2035
Creation of a computer model of the brain and human consciousness with the subsequent development of means to transfer individual consciousness onto an artificial carrier. This development will profoundly change the world, it will not only give everyone the possibility of cybernetic immortality but will also create a friendly artificial intelligence, expand human capabilities and provide opportunities for ordinary people to restore or modify their own brain multiple times. The final result at this stage can be a real revolution in the understanding of human nature that will completely change the human and technical prospects for humanity.
2045
This is the time when substance-independent minds will receive new bodies with capacities far exceeding those of ordinary humans. A new era for humanity will arrive! Changes will occur in all spheres of human activity – energy generation, transportation, politics, medicine, psychology, sciences, and so on.
Today it is hard to imagine a future when bodies consisting of nanorobots will become affordable and capable of taking any form. It is also hard to imagine body holograms featuring controlled matter. One thing is clear however: humanity, for the first time in its history, will make a fully managed evolutionary transition and eventually become a new species. Moreover, prerequisites for a large-scale expansion into outer space will be created as well.
