how can i start with my project?

hi everyone
i am asked to designe and build an optimized electronic circuit that can perform the following:
1- sensing of optical ultrasonic, electromagnetic signal.
2-signal filtering 40KHz and 10KHz .
3-signal amplification.
4-use the signal in certain functions (optional).

circuit ideas:
1- an obstacle avoiding unmanned (hovercraft,vehicle,robot).
2-body or hand tracking system.
3- flying copter that can carry,drop, or follow a target.

my course is electronic =( any advise

What kind of programming/electronics experience do you have?

This sounds like a class project assignment, which must implement requirements 1-4 (4 is optional).

last semester i did voltage doubler it was easier than this :disappointed_relieved:

yes

That's a big jump to this.
Settle on a product you want to make, get it approved, break it down into doable parts.
