Originally Prowler worked from a Sinclair ZX-81, then later an Acorn A3000.
Unfortunately the software is long gone even though the ZX-81 still works.
Following on from making Arduino interfaces for Zero2, Zeaker2, BBBC-Buggy, MM3, and Zeaker I made one for Prowler and so now after thirty years Prowler is again under computer control.

What does the Aduino software enable
The software is built on that written for Bambino then Bamduino. Using a terminal on a PC, commands (see below) can be typed and Prowler controlled. Sixteen Acts can be recorded or loaded into EEPROM and replayed. Any Act can chain to or call any other Act including itself. Eight other ReActs can be recorded or loaded which will be acted upon depending on the state of the bump sensors when the command '$b' is executed.
Prowler knows where it is on an XY grid and can be commanded to go to any position. Navigation is by dead-reckoning so where Prowler thinks it is may not be where it actually is.
Prowler was built very quickly because the magazine - Sinclair Projects - didn't have enough projects. I already had the Tamya motorised tank on the shelf so I used that for Prowler. Unfortunately the tracks have a tendency to come off.

Notes
[(] - will show its location in EEPRO< when played eg (=263
[)] - will show its location in EEPRO< when played eg )=285
If a call to another Act is made from within a Do then the location to return to will be shown, eg (267)
Acts by default are stored in page 1, 0 changes to page 0 for the next command only.
Page 0 ia the first 256 bytes of EEPROM, Page 1 is EEPROM bytes 256-511, ReActs is the next 256 bytes, 
negative numbers allowed for F,B,R,L - so F-20 does B20
