This work reports the preliminary results on a new design concept for bipedal walking robots. The concept is based on the actuators (Linear Induction Motors), and the prospect that these actuators provide to combine passive dynamic walking with active walking. Comprehensive mechanical and dynamic simulations were done to decide the suitable parameter for the actuators and the mechanical design. This paper presents results from the early stages of the actuators simulations until the preliminary result on equilibrium control tested in the real robot. These results show promising outcome on the use of these actuators for more complex equilibrium control and walking algorithms. The energy consumption is a key factor for further consideration of this actuators and design approach.

Societies are formed as collaborative structures to execute tasks which are not possible or are difficult for individuals alone. There are many type of biological societies, but societies formed by machines or robots are still rare. The concept offers, however, interesting possibilities especially in applications where a long term fully autonomous operation is needed and/or the work to be done can be executed in a parallel way by a group of individuals. The paper introduces the basic control and communication structures of robot societies by using a model society. Also a mini-scaled mobile robot which is under construction to be multiplied for the corresponding physical society demonstrator is introduced. Simulation results illustrating the behaviour of the model society are given. Possible applications in waste treatment and process monitoring and cleaning are considered.
