Dev uses Grok bot to turn ESP into an iPhone accessory for syncing robot servos

Baconbrix · x · 2026-10-27

Developer Baconbrix shares that Grok's bot helped turn his ESP chip into an iPhone accessory, letting him sync the servos on his robot directly from his phone — with pairing that works instantly like AirPods.

Because Grok's robot body has very little room for error, he had to pull it apart, sync, and reassemble. His plan is to make the robot feel like a native accessory, and he's surprised at how well it's coming together.
