Its time for a quick update on Robbie the 2 RPIs are working as expected they both run ubuntu mate now. The problem with espeak stalling was resolved by doing an update. The RPI camera works well and moving it to the 2nd RPI (R2) has increased the frame rate. The autoboot is still causing problems upstart will boot the roscore RPI but using the machine feature to launch services on the second RPI only works with a display running. Robbie's head is not fully assembled in the photo I'm still in 2 minds if I'm going to change it or just reprint it. While launching Robbie's system over three computers is a pain at the moment it has some clear advantages only the core RPI needs to be running to navigate the second runs voice and cameras. The third is for moveit and the AI. Once the boot sequence is functioning as expected, the health monitoring side of the AI will move to R2. Power distribution is becoming an issue now the new system will be one button to start the computers and automatically turn off power after the RPIs have shutdown the other systems will be switched on and off as required with MOSFETs all systems will have a switch or a fuse to disable it if required.
