The tracked stroller frame device may allow a user to take a stroller with them when camping, hiking, or otherwise travelling over rough terrain. The device implements a continuous track system for providing additional tractive area and reducing or eliminating getting stuck on uneven surfaces, and may include a motorized mechanism for providing driving force. The tracked stroller device allows a user to take a baby or young child with them without carrying the baby or young child. The device may be collapsible for ease of storage and transporting and may incorporate a storage area to allow for transporting of other items. A braking system may also be implemented to slow down the device or keep it parked.

A stroller track system is used to facilitate the transporting of a stroller up and down stairs. The stroller track system includes a stroller, a left tread assembly, and a right tread assembly. The left tread assembly and the right tread assembly are mounted to a frame of the stroller and are used to engage multiple stairs while traversing a set of stairs. This allows the stroller to glide smoothly up or down the stairs. The left tread assembly and the right tread assembly each include a first track and a second track. Together, the first track and the second track allow the left tread assembly and the right tread assembly to span a larger section of a staircase. The first track is mounted to the frame through a first stroller-attaching mount. A track-securing bracket is used to mount the second track to the frame.

A transportation device and an automatic tilt stabilizer are disclosed herein. The transportation device has a structure with wheels joined by a shaft to a platform or chassis configured to support a basket, a mat, a seat and/or a tray. The automatic tilt stabilizer is configured to automatically stabilize the inclination of the platform or chassis, and includes a tilt sensor configured to detect an inclination of the platform or chassis, and a motor activated by a microcontroller configured to correct the inclination of the platform or chassis, so that the platform or chassis returns to a predefined inclination.

Maneuverable strollers are disclosed. An example stroller includes a frame that includes an upper frame support, an intermediate frame support, a lower frame support, and a handle coupled to the upper frame support. The example stroller also includes a front wheel coupled to the lower frame support, an intermediate wheel having an axis of rotation, and a rear wheel. The intermediate wheel is located between the front wheel and the rear wheel. The intermediate wheel and the rear wheel are coupled to upper frame support via the intermediate frame support. The example stroller also includes a pivot axis, where the intermediate frame support is coupled to the upper frame support about the pivot axis, and the pivot axis is offset above and forward to the axis of rotation.

A stroller can include a body having a pair of driving wheels mounted to left and right sides thereof; a motor configured to rotate the pair of driving wheels; a frame comprising a lower part connected to the body, the frame extending upwards from the lower part; a handle connected to the frame; a sensor unit including a force detection sensor configured to detect force applied to the handle, a touch sensor configured to detect whether the handle is being grasped, and a wheel sensor configured to detect rotation of the pair of driving wheels; and a controller configured to calibrate the force detection sensor based on data detected by the touch sensor and the wheel sensor.

A cart can include a body having driving wheels mounted to left and right sides thereof; a motor configured to rotate the driving wheels; a frame comprising a lower part connected to the body, the frame extending upwards from the lower part; a handle connected to the frame; a sensor unit including a tilt sensor configured to detect a tilt of the body, and a touch sensor configured to detect whether the handle is grasped; and a controller configured to in response to determining that the handle is not grasped based on data detected by the touch sensor, determine whether the cart is located on a slope based on data detected by the tilt sensor, change a control parameter of the motor based on whether the cart is located on the slope and perform a braking operation in different ways based on whether the motor is rotating.
