This is an example robotic construction to show a hypothetical case where a vehicle is being used in future cultivating farms. To save space in future's agriculture, multilevel, raised, crop fields are being cultivated, watered and harvested by a group of 'jack of all trades' robots, which perform a lot of jobs, even bridging trenches, like the one shown in this video. At the end of the video you can see the scratch program that controls robot's behaviour, in synergy with a distance sensor. When the sensor detects the gap of the trench, a bridge is deployed.
