The beginning

The idea:
Build a robot with my son, but what type of robot, what should it do, what should it look like?

When I asked him what he wanted it to do, his reply was clean my room.
I told him we should start with something simple first.
So we came up with a list of functions and features:

1. wheels for movement (we will use an old remote control car)
2. control the car with the computer, then later it will be autonomous
3. range finder
4. motion detector
5. camera
6. talk
7. crash avoidance
8. night/day detector
9. voice recognition
10. it needs to have a light on its chest
11. tell the time and have an alarm
12. temperature/humidity
13. super eat (hearing)
14. battery powered, maybe solar also
15. GPS
16. tilt sensor (if it falls over)
17. termal array sensor

Some of these will produce significantly different robots, so the plan is to start small and add features, then build multiple models.

One that moves on wheels and one that walks.

Now to find a microcontroller that will do the job.
