PROBLEM DEFINITION VERSION 1.2

Design an automata toy for user which operates like a gear system. It should be portable semi automatic with beep system and it ensured waterproof and easily programmable by the user and it should stop when a user removes their hand. It costs between ₹2500 - ₹3500 which has a size of 30cm20cm12cm having rectangular shape of weight 1.5g, and the sensors in it.

3.5 ESTABLISH FUNCTIONS

Sl.no	Functions
1	Buzzer indicator
2	Replying to the commands
3	Gear shifting mechanism

PROBLEM DEFINITION VERSION 1.3

Design an automata toy for user which operates like a gear system. It should be portable semi automatic with beep system and it ensured waterproof and easily programmable by the user and it should stop when a user removes their hand. It costs between ₹2500 - ₹3500 which has a size of 30cm* 20cm *12cm having rectangular shape of weight 1.5kg, and the sensors in it. It should sense the hand motion and turn on the engine, there should be a indication for the starting of the engine. After starting the gears should be shifted manually and input gear should be shown in the digital gear indicator. As the gear increases, the speed should be increase.
