I want to impress every guest in my place , and I'm kinda lazy at the same time. so here is my solution：1, use vxq-01 long reach 6 dof arm, which is very powerful and adaptable as actuator 2, build a beacon pad with QR code and 2.4G transceiver 3, run python on Raspberry pie to control vxq arm.
End-of-arm tooling done
