The prototype lettuce harvesting robotic | Supply: IDS Imaging
Lettuce is a helpful crop in Europe and the USA, however labor shortages make it tough to reap this helpful area vegetable, as sourcing adequate seasonal labor to satisfy harvesting commitments is among the sector’s greatest challenges. Furthermore, with wage inflation rising quicker than producer costs, margins are very tight.
In England, agricultural expertise and equipment specialists are working with IDS Imaging Improvement Methods GmbH, primarily based in Obersulm, Germany, to develop a robotic answer to automate lettuce harvesting. The group is engaged on a venture funded by Innovate UK and consists of specialists from the Grimme agricultural equipment manufacturing unit, the Agri-EPI Centre in Edinburgh, UK, Harper Adams College in Newport, UK, the Centre for Machine Imaginative and prescient on the College of the West of England in Bristol and two of the UK’s largest salad producers, G’s Recent and PDM Produce.
Throughout the venture, present leek harvesting equipment is tailored to carry the lettuce clear from the bottom and grip it in between pinch belts. The lettuce’s outer, or ‘wrapper’, leaves might be mechanically eliminated to show the stem. Machine imaginative and prescient and synthetic intelligence are then used to establish a exact minimize level on the stem to neatly separate the pinnacle of lettuce.
“The reducing means of an iceberg is probably the most technically sophisticated step within the course of to automate, in line with teammates from G subsidiary Salad Harvesting Providers Ltd.,” IDS Product Gross sales Specialist Rob Webb stated. “The prototype harvesting robotic being constructed incorporates a GigE Imaginative and prescient digital camera from the uEye FA household. It’s thought of to be notably strong and is subsequently ideally suited to demanding environments. “As that is an out of doors utility, a housing with IP65/67 safety is required right here.”

The selection fell on the GV-5280FA-C-HQ mannequin with the compact 2/3″ world shutter CMOS sensor IMX264 from Sony.
“The sensor was chosen primarily due to its versatility. We don’t want full decision for AI processing, so sensitivity will be elevated by binning. The bigger sensor format signifies that wide-angle optics should not wanted both,” Rob Webb stated.
The prototype of the robotic mower might be used for area trials in England in the direction of the tip of the 2021 season.
“We’re delighted to be concerned within the venture and look ahead to seeing the outcomes. We’re satisfied of its potential to automate and enhance the effectivity of the lettuce harvest, not solely when it comes to compensating for the dearth of seasonal employees,” Jan Hartmann, Managing Director of IDS Imaging Improvement Methods GmbH, stated.
The challenges dealing with the agricultural sector are certainly complicated. In line with a forecast by the United Nations Meals and Agriculture Organisation (FAO), agricultural productiveness should enhance by nearly 50% by 2050 in comparison with 2012 as a result of dramatic enhance in inhabitants. Such a yield expectation means an unlimited problem for the agricultural trade, which remains to be in its infancy when it comes to digitalization in comparison with different sectors and is already underneath excessive stress to innovate in view of climatic adjustments and labor shortages.
The agriculture of the longer term is predicated on networked units and automation. Cameras are an essential constructing block, and synthetic intelligence is a central expertise right here. Good purposes reminiscent of harvesting robots could make a big contribution to this.
