The following video clips illustrate some of the technology that we have developed in recent years. To view a clip click on the thumbnail picture. A brief description is provided against each thumbnail. Further information can be found by clicking on the text link within the description. Each video is in Windows Media File format, runs for between 30 seconds and 3 minutes and is between 4MB and 18MB in size.
In most cases alternative links have been provided to YouTube versions of the movies that will play on a wider range of platforms. Also see www.youtube.com/c/nicktillett .
This vision guided spot sprayer was developed as part of a collaborative project and is shown here in its commercial form controlling volunteer potatoes in carrots. parsnips, peas and onions. Follow this link for a YouTube version.
The technology behind this Robocrop within-row weeder was developed as part of a collaborative project and is shown in its hydraulically powered form operating here in a brassica crop. Follow this link for a YouTube version.
As part of a programme of continuous improvement we have developed an In-row weed with electrically powered rotors. This enables us to achieve even higher speeds (5 plants/s) at higher accuracy with a very low power input. Follow this link for a YouTube video of a 20 rotor machine operating in lettuce.
This precision drenching application is based on a combination of our in-row weeding and our spot spray technology. The challenge is to accurately place a slug of water close to the roots for maximum efficiency. Applications of this technology might include fertilizer or crop protection product placement.

Automatic thinning of drilled crops could dramatically reduce labour requirements. This mechanical thinner works well under suitable soil conditions, but we have got even better results using the same algorithms to control a thinner based on selective herbicide application. Follow this link for a YouTube version of the mechanical thinner.
Robocrop inter-row cultivators are now widely used to improve the efficiency and quality of inter-row cultivation whilst reducing driver work load.
This 12m span high work rate inter-row hoe comprises three 4m cultivator sections each with its own camera and side shifting frame enabling it to span three independent drill bouts. It is operating in an organic cereal crop. Follow this link for a youtube version.
This 20m span high work rate vision guided band sprayer uses four cameras and four side shift sections. Precision placement provides opportunities for more effective treatment using less material. Follow this link for a YouTube version
This autonomous vehicle represented the start of our vision guided work and was publicly demonstrated in 1996. Guidance down rows was relative to crop rows and individual crop plants were squirted as an array of nozzles passed over them.
