A mobile device (e.g., wireless wheeled vehicle) that includes one or more propulsion mechanisms (e.g., one or more drive wheels) and a member (e.g., a mechanized tail). The propulsion mechanism(s) are operable to propel the mobile device across a driving surface. The member is positionable to maintain or change an orientation of the mobile device with respect to the driving surface. The member has a base portion opposite a free end portion. The base portion is pivotably mounted to a portion of the mobile device. The base portion is pivotable to move the free end portion toward and away from the driving surface.

A device includes a signaling means and a motion sensor, and logic for activating or controlling the signaling means in response to a sensed motion according to an embedded logic. The device may be used as a toy, and may be shaped like a play ball or as a handheld unit. It may be powered from a battery, either chargeable from an AC power source directly or contactless by using induction or by converting electrical energy from harvested kinetic energy. The embedded logic may activate or control the signaling means, predictably or randomly, in response to sensed acceleration magnitude or direction, such as sensing the crossing of a preset threshold or sensing the peak value. The visual means may be a numeric display for displaying a value associated with the count of the number of times the threshold has been exceeded or the peak magnitude of the acceleration sensed.

In an aspect, a toy assembly is provided, and includes a toy assembly housing, an extensible object inside the toy assembly housing, an extension mechanism, and an extension member power source. The extensible object includes a base, and first and second extension members. The extension mechanism is operable to drive the first and second extension members towards extended positions, and is operatively connected to the second extension member via a lost motion connection. Driving of the extension mechanism by the extension mechanism power source drives the first extension member towards the extended position for the first extension member to break or open the toy assembly housing to expose the extensible object while consuming at least a portion of the lost motion in the lost motion connection. Upon consuming the lost motion, further driving the extension mechanism drives the first and second extension members towards the extended positions.
