I’m working on my first robot. It’s a mecanum-wheel platform with a head that can rotate 360 degrees using a stepper. I’m thinking of putting some simple actuators and/or sensors on the head, but the central microcontroller is on the body. Has anyone used wireless to couple two parts of a robot that are inconvenient to hardwire? Or is there a hardwire system designed for this kind of problem?
The central microcontroller is an Arduino MKR1000 to which I’m sending commands in OSC over WiFi. I’ve considered just putting a second one on the head with a compact LiPo battery and have them chat among themselves, but I think that means I’d always have to have a wireless router nearby, even when it’s running autonomously. I’ve looked into Bluetooth and 915MHz transceivers but am wondering if there is a standard solution to this problem that experienced builders use.
