Abstract:
1. A method of remote controlling an altitude of a toy flying vehicle intended for indoor operation, the vehicle having a rotor for rotation relative to a fuselage of the vehicle, and a separate remote controller for use by a player of the toy, the method comprising: (a) providing a relative selected altitude level r′d corresponding to a selected altitude for the vehicle; (b) transmitting a position control signal with a light intensity I from the vehicle towards a surface; (c) determining if a reflected signal of said position control signal is received from the surface; (d) increasing a counter CNT if said reflected signal is received; (e) increasing said light intensity I; (f) repeating steps (b)-(e) while said light intensity I is less than a maximum value; (g) determining a relative altitude r′ and adjusting rotor action according to a difference between the relative altitude r′ and the relative selected altitude level r′d to retain the selected altitude, wherein said determining the relative altitude r′ comprises selecting the relative altitude r′ from a table comprising correlations between values for the relative altitude r′ and values for the counter CNT; and controlling the toy by a control selected from at least one of a stop control; an altitude control by at least one of an up control; down control; a high height sensitivity control and a low height sensitivity control; take-off/landing control; gesture mode control; left/right trim control; control between altitude control mode and manual control mode.
