Create a ai enabled toy car which never falls from table edge. It should detect table edge, apply break and turn when reaching edge of table. Sensors should detect table edge, it should maintain safe distance from table edge.
Even if I push the wheels in the direction of edge for car to fall, car should make turn just before falling and ensure it does not fall. IOT (internet of things), sensors may be used to achieve this.
On similar lines, toy car never hitting walls can be developed. Car should turn away before hitting wall.
Such an AI enabled toy will be in great demand. May trigger a chain of innovations in toy industry.
