Deep-Plowing Experiment
W hat constitutes “long-term” research may be as apparent as collectable art; although many are quick to identify the plots in Rothamsted-UK, started in 1843, as the gold standard of long-term research. When researchers conduct experiments in reference to a hypothesis that determines treatment application, the test duration usually lapses after a few “climatically representative” years. Mr. O. ...
متن کاملSynchronized arc routing for snow plowing operations
This paper introduces a synchronized arc routing problem for snow plowing operations. In this problem, routes must be designed in such a way that street segments with two or more lanes in the same direction are plowed simultaneously by different synchronized vehicles. A mixed integer formulation and an adaptive large neighborhood search heuristic are proposed. The performance of the proposed al...
متن کاملDiesel Fuel Consumption During Chisel Plowing
Introduction Direct energy expenses (diesel, gasoline, propane, electricity) total more than $1 billion annually for Iowa farmers. Farm management techniques such as adjusting tractor gear and throttle settings or reducing tillage depths can reduce diesel fuel consumption for row crop production. This study is being conducted over multiple years to measure the effects of energy management techn...
متن کاملPlowing for Controlled Steep Crater Descents
Controlling slip is crucial to reliable descent of steep unconsolidated slopes such as those found in lunar craters. The ability to enter these craters provides opportunities to explore potential in-situ resources, such as water ice. We present a rover prototype with a novel, actuated, omni-directional plowing device and control method for maneuvering on steep slopes. Data from field experiment...
متن کاملPlowing for Rover Control on Extreme Slopes
Planetary rovers are increasingly challenged to negotiate extreme terrain. Early destinations have been benign to preclude risk, but canyons, funnels, and newly discovered holes present steep slopes that defy tractive descent. Steep craters and holes with unconsolidated material pose a particularly treacherous danger to modern rovers. This research explores robotic braking by plowing, a novel m...
