Public presentations

  • The second public demonstration is September 24, 2014. The Grassbots robot will be demonstrated performing fully autonomous cutting of a lowland area. This is based on a FroboMind application (robot behaviour and navigation) developed by the University of Southern Denmark, route planning from Aarhus University interfaced to FroboMind through common file and socket interfaces (the latter supports dynamical route plans), the Lynex tool carrier, the Kongskilde JF Stall mower implement, everything integrated by Conplex Innovation through their RoboTech Controller.
  • The first public demonstration was 2013-09-26 at Agro Business Park in Denmark (invitation) where the medium sized grass cutting robot was demonstrated. This version consists of a Lynex tracked tool carrier based on hydraulics propulsion and a grass cutting implement from Kongskilde Industries. The overall design is by Bertelsen Design, Conplex Innovation has performed the integration including robot computer and low level control software and the University of Southern Denmark has provided a FroboMind application for autonomous area coverage.
