Abstract

A control program for a programmable toy (24) is created using a graphic programming system implemented on a personal computer (10). In the preferred embodiment, the programmable toy comprises a vehicle that can be commanded to make turns in 45° increments and to track an infrared source (220). To create the graphic control program, the user simply selects graphic objects from control panel (154) presented on a cartoon-like graphic screen. For example, the user can select a horn graphic object (168) or a headlight graphic object (166) to respectively activate a horn or headlights on the programmable toy. The user creates a graphic control program on a grid (160) using a mouse (23) to select the graphic objects and indicate parameters. Once the graphic control program is completed, it is downloaded from the RS-232 serial port of the personal computer into the programmable toy through a connecting link (25), which is then uncoupled from the programmable toy. A switch (29) on the toy activates the control program. Also included in the system is a calibration template (200) for calibrating the programmable toy to turn accurately on a specific surface.

Claims

1. A method for calibrating an angular response on a specific surface of a toy vehicle controlled by a program, comprising the steps of:

(a) positioning the toy vehicle on the specific surface;

(b) commanding the toy vehicle to make a specified angular turn on the specific surface;

(c) measuring the toy vehicle'"'"'s actual response to the command; and

(d) entering the toy vehicle'"'"'s actual response to the command as input data for the program that controls the toy vehicle, said program responding by correcting subsequent commands to turn the toy vehicle for the toy vehicle'"'"'s actual response, so that the toy vehicle makes turns that are corrected for its response on the specific surface.

2. The method of claim 1, wherein the step of measuring the toy vehicle'"'"'s actual response comprises the steps of providing an angular grid;

and, placing the toy vehicle on the angular grid before the step of commanding the toy vehicle, said angular grid indicating the toy vehicle'"'"'s actual response.

3. The method of claim 1, further comprising the steps of determining the toy vehicle'"'"'s response on a plurality of different surfaces;

and, entering the actual response on each different surface to enable the program to correct for errors in turning response on each surface.

4. The method of claim 1, further comprising the steps of commanding the toy vehicle to turn a plurality of different angles;

measuring the toy vehicle'"'"'s actual response for each of said different angles; and

, entering the actual response for each of said different angles, said program thereby correcting for different actual responses on the specified surface when the toy vehicle is commanded to turn through said different angles.

5. The method of claim 1, wherein the step of measuring the toy vehicle'"'"'s actual response comprises the step of providing a sensor that senses the actual response and produces a signal indicative thereof for input to the program as input data.

6. The method of claim 5, wherein the sensor comprises a wheel that is rotatable in a plane that pivots as the toy vehicle turns, said sensor including a transducer that produces said signal indicative of the toy vehicle'"'"'s actual response.
