Vintage Horticultural and Garden Machinery Club

Came across another article in a Agricultural Machinery Journal from 1970 reporting the development of Richardson Automatic Cultivating Equipment which used a Ransomes MG as the development testbed.
The MG with mounted ploughs at front and back was driverless and used a sensor controlled pneumatically controlled operation system invented by a Mr Richardson who had received financial backing from The National Research Development Corporation to develop the system into a three furrow form.
At the demonstration the performance was described “as erratic at times” with numerous minor difficulties to overcome !!!!!!
I wonder did it survive ? Mr Richardson would now be 90 so is probably not around but would it qualify for a vintage horticultural ploughing match ?? probably too late a model. Probably my sense of the ridiculous but a vision of sensor malfunction and it heading off across adjacent plots and resulting mayhem raise a smile. I suppose without driver insurance cover would not be available for public operation.
Is there any limit to the uses these Ransomes MG’s were put to, you cannot help but wonder if Ransomes had developed the Winget adaption construction side and embraced the hydraulic equipment/drives being developed there was a market or perhaps they did not want to upset other manufacturers in the market to the detriment of the Ransomes cultivation equipment
