Toy car RoGer RO-3739 with sound and light effects, battery-powered mechanical play vehicle

The RoGer RO-3739 is an 8-wheeled remote-controlled toy car with sound and light effects, designed for battery-powered mechanical play. Its adjustable wheel configuration and wheel transformation function on the controller let the chassis height be changed so the vehicle can overcome varied surfaces and obstacles, including steps. The set includes both a classic handheld controller and a wrist controller for gesture-based operation, plus a rechargeable battery and accessories for charging and minor maintenance.

Advantages

The eight-wheel design and adjustable chassis provide improved obstacle clearance and stable movement on uneven surfaces. Integrated music, lights and a steam-like exhaust add sensory feedback during play. Two control options — a traditional remote and a wrist controller — increase flexibility of use. The included rechargeable 3.7 V 500 mAh battery eliminates the need for immediate disposable batteries for the car itself.

Suitable for

• Indoor and outdoor play on flat and uneven surfaces
• Obstacle negotiation and simple stunt play (ramps, curbs, stairs)
• Developing hand-eye coordination and motor skills
• Interactive play using gesture control or standard remote
