The invention relates to a wheel-foot robot. The wheel-foot robot comprises a robot body, two symmetrically-arranged wheel-foot assemblies and at least four driven omnidirectional wheels. Each wheel foot assembly comprises a driving walking wheel driven by a hub motor and a Chebyshev four-connecting-rod mechanism connected with the machine body and the driving walking wheel.

3D flexible spikes mounted on running wheels or drive wheels. Their highly flexible design significantly reduces the problem of contamination and improves traction. The combination of mounting and suspension also considerably reduces manufacturing costs. Current research indicates that numerous flexible spikes exist, and their properties can be further customized. In all applications, the spikes are guided in a reversible direction and held flexibly on this axis by mechanisms. See our European patent application EP23197209.2. A comprehensive prior art search has already been conducted for this application. In this version, the spikes are mounted three-dimensionally (Fig. III flexible working paths, items 10, 11, 12, and 16). This means the spikes are flexible in all directions and their working path can be restricted by guides, including adjustable guides. These wheels are typically used as drive wheels, where permanently optimized traction is beneficial. Due to the individual adjustment of the spikes, balancing is difficult, and the wheels with flexible spikes should be used at low speeds. The spikes' flexibility in all directions allows the wheels to adapt to ground conditions and facilitates cleaning. The 3D design significantly reduces damage and wear on the spikes. In conjunction with a guide (optionally adjustable) on the vehicle / equipment, the properties of the spikes can be influenced at different positions on the wheel.
