get a - roomba create 3 for 400 - arm built of dynamixel servos for 200 - camera for 100-500 (stereoscopic will set you back but its worth it) - nvidia jetson nano orin nx (500)

for about 2k, you can make a robot that can clean your house and is probably smarter than a dog/cat

Regarding the arm, are you thinking of a particular kit?

Those servos look really interesting, so you can read their position via a UART type interface? I've only played with cheap PWM servos before.

Thanks, that's very interesting, bookmarked! I found https://github.com/thomashiemstra/fred whilst searching, which also uses dynamixel motors, but very expensive ones.

It does look very smooth motion-wise though!
