A rolling and jumping toy resting on the ground, including: - a wheeled carriage, comprising a carriage and a pair of wheels arranged on either side of the carriage, the wheels being mounted with respect to the carriage so as to rotate about a common axis perpendicular to the main direction (Δ) of the carriage; - a sliding part, mobile in a guided translation along the carriage, between two extreme positions, respectively extended and retracted; - releasable means for locking the position of the sliding part with respect to the carriage; - first motor means, adapted to exert on the wheels a rotation torque with respect to the carriage; - second motor means, adapted to move the sliding part with respect to the carriage; - a spring member stressed between the carriage and the sliding part; and - spring-member control means, adapted i) to progressively store a mechanical energy in the spring member by displacement of the sliding part towards the retracted position under the action of the second motor means, and ii) to release the thus-stored energy, hence driving the sliding part towards the extended position under the effect of a release of the locking means, said toy being characterized in that: - the carriage supports a first jaw; - the sliding part includes a protruding distal end supporting a second jaw, located opposite the first jaw, and mobile with the sliding part, as well as a contact pad; - it moreover includes position control means, adapted to pilot in a coordinated manner the first and second motor means so as to move the carriage into rotation with respect to the ground, selectively between at least two functionally distinct stable positions, comprising:. a default position, where said pad bears on the ground, the toy resting in stable equilibrium on the two wheels and said pad; and. a shooting/grasping position (52, 60), where the toy rests in stable equilibrium on the two wheels with the distal end of the sliding part directed towards the ground, and where the second jaw is movable in a controlled manner parallel to the ground, further or closer to the first jaw. - a wheeled carriage, comprising a carriage and a pair of wheels arranged on either side of the carriage, the wheels being mounted with respect to the carriage so as to rotate about a common axis perpendicular to the main direction (Δ) of the carriage; - a sliding part, mobile in a guided translation along the carriage, between two extreme positions, respectively extended and retracted; - releasable means for locking the position of the sliding part with respect to the carriage; - first motor means, adapted to exert on the wheels a rotation torque with respect to the carriage; - second motor means, adapted to move the sliding part with respect to the carriage; - a spring member stressed between the carriage and the sliding part; and - spring-member control means, adapted i) to progressively store a mechanical energy in the spring member by displacement of the sliding part towards the retracted position under the action of the second motor means, and ii) to release the thus-stored energy, hence driving the sliding part towards the extended position under the effect of a release of the locking means, - the carriage supports a first jaw; - the sliding part includes a protruding distal end supporting a second jaw, located opposite the first jaw, and mobile with the sliding part, as well as a contact pad; - it moreover includes position control means, adapted to pilot in a coordinated manner the first and second motor means so as to move the carriage into rotation with respect to the ground, selectively between at least two functionally distinct stable positions, comprising:. a default position, where said pad bears on the ground, the toy resting in stable equilibrium on the two wheels and said pad; and. a shooting/grasping position (52, 60), where the toy rests in stable equilibrium on the two wheels with the distal end of the sliding part directed towards the ground, and where the second jaw is movable in a controlled manner parallel to the ground, further or closer to the first jaw.. a default position, where said pad bears on the ground, the toy resting in stable equilibrium on the two wheels and said pad; and. a shooting/grasping position (52, 60), where the toy rests in stable equilibrium on the two wheels with the distal end of the sliding part directed towards the ground, and where the second jaw is movable in a controlled manner parallel to the ground, further or closer to the first jaw.
