Marvin: Marvin does look like an off-the-shelf Model-3 ElectroClasmBot. And he certainly meets or exceeds all the standard ElectroClasm type 5 protocols. But he is especially proud of a few custom upgrades: a) Autonomous Firmware release: 7.0.3 (the latest) b) Peizio Servo-Flambulator? No way. Marvin is Peizio free! (an obvious advantage) c) Self-adjusting thermal Braxon coupling. d) Cool big feet.
