Samsung Powerbot vr9000 reverse engineer PCB connections
You should look at other boards in this robot. In front part there is
Robot vacuum cleaner (RVC) module from CLABSYS http://www.clabsys.com/html/product_module01.html with:


128 MB flash chip (ESMT F59L1G81A)
128 MB RAM chip (SAMSUNG K4T1G164QG)
Application processor (NEXELL NXP2120    http://www.nexell.co.kr/kor/pro/pro01.html)
Ceiling Camera
USB connection


and sensor board with:


Unknown chip (SAMSUNG HART-m310)
Front looking camera (it looks up but have fancy mirror to see 180° front view)
5A Brushed DC Motor Driver (TI DRV8840)
connector labeled JTAG


I got all Samsung provided source for open source products in VR20H9050UW and there is source for UBOOT, Linux KERNEL 2.6.32, ROOTFS, Linux utilities (alsa, libusb, ncurses, squashfs and zlib), toolchain for building everything and Nexell USB Downloader Driver. So using this USB connection on RVC module there should be a way to upload new firmware. It could be that using same USB connection someone can access already uploaded firmware and extract file system content from it. But we need documentation from CLABSYS (or Nexell) how to do it.
