Found this cheesy sci-fi serial which is apparently public domain, the announcer is apparently desperate to remind us of the lead character’s name. Clunky looking robot in this episode called imaginatively Roger (could have been Robert I suppose!) and Z-ro is able to conduct experiments in time and space.

It’s like a 50s Retro Doctor Who without the Tardis or the quality of the writing.
