Abstract

A robotic life form simulates a live creature responsive to a changing environment sensed by the robot, and has a robotic body that is articulated for motion around an upright axis and supported by at least two legs, each having at least two joints. The neck of the body terminates in a head provided with eyes and a mouth, and, in the illustrated creature, has a tail. Internal and external input sensors are located on the robotic body and responsive to touch, sound and lighting conditions, motion, food, temperature, voice commands, time of day, and obstacles and hazards, and include a head touch sensor, a plurality of touch sensors extending along a torso of the body, and a plurality of touch sensors on the feet. Actuators responsive to the input sensors control the eyes of the robot, opening and closing of its mouth, movement of the head, movement of the neck relative to the torso, and relative movements of the front and rear sections of the torso to cause the torso to pivot and twist and thereby provide lifelike responses to the sensed conditions. Drive index levels in accordance with priority criteria selected from a plurality of animation groups determine the drive index levels, and servo actuators associated with the body are responsive to dominant drive indexes causing the robot to execute animations resulting therefrom.

Claims

1. A robotic life form simulating a live creature responsive to a changing environment sensed by the robot, said robot comprising:

a robotic body articulated for motion around an upright axis and supported by at least two legs terminating in respective feet, each of said legs having at least two joints, said body having a neck terminating in a head provided with eyes and a mouth,

internal and external input sensors located on said robotic body and responsive to touch, sound and lighting conditions, motion, food, temperature, voice commands, time of day, and obstacles and hazards, including a head touch sensor, a plurality of touch sensors extending along a torso of said body, and a plurality of touch sensors on said feet,

means responsive to said sensors for determining drive index levels in accordance with priority criteria selected from a plurality of animation groups comprising a mood of the robot, a physical state of the robot, a state of the robot determined by food, health of the robot, and an emotional state of the robot, and

a plurality of servo actuators associated with said body and responsive to dominant drive indexes for causing the robot to execute animations resulting therefrom.

2. The robotic life form as claimed in claim 1, wherein a first of said actuators controls said eyes of the robot, a second of said actuators controls opening and closing of said mouth, a third of said actuators controls movement of said head, a fourth of said actuators controls movement of the neck relative to the torso, and a fifth of said actuators controls relative movement of front and rear sections of said torso to cause the torso to pivot and twist, whereby to provide life-like responses to the sensed conditions.

3. The robotic life form as claimed in claim 1, wherein said mood of the robot corresponds to one of a plurality of drive index levels from very sad to very happy, said physical state corresponds to index levels from very exhausted or sleepy to very energetic, food drive index levels are established from very hungry to overfed and sick, health drive index levels are established from very sick to very healthy, and emotion drive index levels are established from very fearful to very excited.

4. The robotic life form as claimed in claim 1, further comprising means in said robot establishing born-in attributes including gender, activeness, temperament, obedience, tone, volume and intelligence.

5. The robotic life form as claimed in claim 3, wherein said robot is a male, characterized by agility, bad temperament, stubbornness, low tone, loud volume, and slow intelligence.

6. The robotic life form as claimed in claim 3, wherein said robot is a female, characterized by quietness, good temperament, obedience, high tone, quiet volume, and sharp intelligence.

7. The robotic life form as claimed in claim 3, wherein the robot is of neuter gender characterized by normal activeness, temperament, obedience, tone, volume and intelligence.

8. The robotic life form as claimed in claim 1, wherein said robotic body is provided with a sound sensor, means responsive to loud sounds for playing scared animations and updating behavior indexes, playing sound-detected animations in response to lower level sounds, or animations associated with a sonic code received.

9. The robotic life form as claimed in claim 1, wherein said input sensors include a mouth infrared sensor, foot infrared sensors, and a G-sensor for initiating play animations in response to the mouth and foot sensors and animations associated with directional impact and movement.

12. The robotic life form as claimed in claim 1, wherein said input sensors respond to petting positively and update mood and emotional drive indexes, respond to a hit negatively by updating mood, emotional and temper drive indexes with a negative effect and updating corresponding drive indexes, and respond to a touch by triggering animations corresponding to the touch signal location.

13. The robotic life form as claimed in claim 1, wherein said robotic body has a tail articulated for motion with respect to said body, and a tail up-down servo actuator and a tail side-to-side servo actuator coupling the tail to a rear of said torso in response to an output drive.

14. The robotic life form as claimed in claim 1, wherein said robotic body has male born-in attributes of agility, bad temperament, stubbornness, low tone, loud volume, and slow intelligence.

15. The robotic life form as claimed in claim 1, wherein the robotic body has neuter born-in attributes of normal activeness, temperament, obedience, tone, volume, and intelligence.
