Plenty of autonomous lawnmowers have been showcased or introduced at this year’s IFA event in Berlin, but only one of them comes equipped with a robotic arm. NexLawn, a sub-brand of MOVA that sits under its Dreame parent company, has announced the Master X Series Concept, which it describes as “the first robotic mower with a fully functional mechanical arm.”
That arm is designed to help reduce the amount of manual maintenance that’s required for people who own and run robot lawnmowers, such as picking up any fallen sticks or debris that could damage the bot or force it to navigate around the obstacle. The arm folds down to 44.5 cm (about 17.5 inches) in length, extends up to 77 cm (a little over 30 inches), and can reach as far as one meter away when performing outdoor tasks. NexLawn says it features multiple interchangeable arm attachments, including a multi-gripper, a trimmer head, and an edging disc head, with more in development.
