Hope everyone has been having a blast building robots!
I haven't posted since last year and now its time to scramble and get the G-Bot ready for this Halloween. Always a fun time!
This year the G-Bot is getting upgraded from v3 to v4. I am excited to enjoy the better range and connectivity of wifi over Bluetooth. I’m also upgrading his neon power supply, adding a couple more Sabertooth (2x12s) controllers (to work on some arm functionality) and adding three Kangaroo auto-tuners to make control of the drive and arm motors a lot simpler.
I am also correcting a few design flaws I learned about last year. I’ll be connecting a cutoff relay to his power pack to directly disconnect power from his drive motor controller in the event he runs amok again…
I’ve been picking people’s brains for thoughts and ideas since this is a process a little outside my scope and an electrical engineer friend of mine talked about how industrial robotic systems are designed. He said I should consider a controller dedicated to only monitoring the health and performance of the other controllers. In the event of a lockup or other type of failure the monitoring controller can shut one down or run other scripts as needed.
The old G-Bot setup used two EZB v3s, one in the lower half and one in the torso section. Since I’m swapping them out to v4s, I really will have no use for the v3s.
Anyone know if its possible to use one of the v3s to monitor the two v4s? Can a v3 be direct connect to two v4s for this purpose? If so, I’ll need to also upgrade the slip ring that connects the two sections of the G-Bot since right now they only have enough conductors to connect power.
Does the EZB v4 also support Bluetooth? If so, I wouldn’t have to change the slip ring.
Any thoughts or links or other information would be greatly appreciated!
