The Tetrabot walking platform for service robotics consists of unique wheel-stepping movers that provide high cross-country ability, debris, rubbish heaps, ditches, as well as staircases. The developed kinematics makes it possible to ensure high clearance and low vibrations both vertically and in the linear velocity of reference points. Analysis and calculations show a significant advantage of these walking modules over biomorphic propulsion systems in terms of energy efficiency and traction characteristics. Energy efficiency is provided by fewer marching engines (one versus three for biomorphic on each limb) and the absence of idle movements while walking.

Traction characteristics are higher due to the fact that at any time each walking walking module of Tetrabot has effective contact with the surface, while robots with biomorphic propulsion devices have contact with the surface during movement only half of their limbs. The robots created on the basis of the Tetrabot walking platform and an autonomous system for adapting to difficult terrain will be in demand in the mining, forestry and agricultural industries, in housing and communal services – for robotic cleaning of territories and flights of stairs, in landfills for primary sorting of garbage, in the Ministry of Emergencies – for searching and salvation of people in the rubble, and in the future for the active development of the Arctic and other planets. To fulfill these and other goals, it will be possible to install the necessary attachments on our walking platform, due to which the walking platform can be transformed into a specialized industrial robot.

And what is the advantage of your solution over biomorphic walking robots?

Bio-like walking structures maneuver perfectly, have increased adaptability to road bumps .. The most prominent representatives are the big dog, spot mini, ANYmal and other analogues. But they also have their drawbacks. High energy costs – a lot of servos, sensors and neurochips consume a lot of precious energy. Raising and lowering legs also consumes energy since energy recovery during lowering legs in these designs is ineffective. And the pendulum movements of the legs and the need for constant terrain analysis reduce the speed of movement. In addition, the high cost of such robots is not an unimportant factor.

The mechanisms of your robots resemble an ordinary tripod – what’s the difference?

The main disease of wheel-stepping movers is vibrations and tremors that occur during the walking process. And if you rotate a simple tripod, then the oscillations of the axis will reach 50% of the length of the legs. Moreover, spurious oscillations are manifested not only vertically, but also for the speed of reference points. And if for small robots these vibrations can be ignored due to the light weight of the robot and flexible joints, then for larger and more powerful counterparts, the vibrations turn into destructive for the structure, engines and mechanisms of the robot. And if it is a courier robot, then the same is for transported goods. Therefore, the main emphasis was placed on the development of a mechanism of a wheel-step propulsion with a compensator for spurious oscillations.

As a result, after several months of searching, a solution was found. Thanks to the original compact vibration compensator, the problem was solved. The optimal parameters of the mechanism reduced vertical vibrations to 5%, and the speed fluctuations of reference points to 6.5%. To move along an uneven surface, these residual vibrations are almost imperceptible.

Why did you decide to develop not only service robots but also educational designers?

The developed mechanisms are perfect for creating small and inexpensive robots. And today, it’s the robotic, educational designers that are most in demand – after all, robotics is the profession of the future. In addition, the designer being developed will include not only mechanical components and electronics, but also the unique software product “Artificial Intelligence Designer”, which will make it easy to connect various recognition modules and decision-making modules. We can say that on the designer, users will be able to test modern solutions in the field of artificial intelligence before these solutions are installed on powerful service robots. Thus, the educational designer will help to test many different software solutions and choose the most successful and optimal solutions that will be ported to service and industrial robotics.
