D&M computing Model 001-00020
I'm unsure of the model number, this is an early example of a dedicated Armdroid 1 controller produced by D&M which subsequently bought the rights to Armdroid.
This type of controller would be used if no general purpose computer was available. If you look closely in the pictures, you can make out the commands for editing sequences of commands, and loading/saving to cassette tape.
Armdroid 5101 controller
Not exactly sure, but i suspect this was manufactured by LabVolt. I would imagine this type of controller would supplement computer control but may also conduct the sequencing of commands itself.
