Motion coordination and programmable teleoperation between two industrial robots

Tasks for two coordinated industrial robots always bring the robots in contact with a same object. The motion coordination among the robots and the object must be maintained all the time. To plan the coordinated tasks, only one robot's motion is planned according to the required motion of the object. The motion of the second robot is to follow the first one as specified by a set of holonomic equality constraints at every time instant. If any modification of the object's motion is needed in real-time, only the first robot's motion has to be modified accordingly in real-time. The modification for the second robot is done implicitly through the constraint conditions. Thus the operation is simplified. If the object is physically removed, the second robot still continually follows the first one through the constraint conditions. If the first robot is maneuvered through either the teach pendant or the keyboard, the second one moves accordingly to form the teleoperation which is linked through the software programming. Obviously, the second robot does not need to duplicate the first robot's motion. The programming of the constraints specifies their relative motions

Kandungan Unsur Hara dan Bakteri Patogenik dalam Substrat dan Lumpur Buangan Biogas Feses Sapi Bali

Nutrients Content and Pathogenic Bacteria in Subtrates and Bio Gas-Sludge of Bali Cattle's Feces. The biogas processing is one approach to overcome this issue. Bali cattle's feces produce serious impacts on pollution and could be a source of infectious disease when treating worst. The objective of current research was to evaluate the nutrient content and pathogenic bacteria within biogas sludge from Bali cattle feces. The research was conducted from January to September 2014. The samples used were substrate and biogas sludge of Bali cattle feces taken from 10 biogas installations owned by farmers in Setanggor village Central Lombok District. The content of nutrient within the biogas sludge was analyzed from the samples using Atomic Absorption Spectrophotometer. Counting the number of colony method (Plate Count) in Nutrient Agar media was used to examine the total of bacteria colony and the Most Probable Number (MPN) in Mc. Conkey Agar media was used for counting the total of Coliform bacteria. The result showed that biogas sludge of Bali cattle feces contained nutrients such as N, P, K, Na, Ca, Mg, Fe, Mn, Cu, Zn and organic C. The organic C nutrient was the highest (42.64%). It also proves that the biogas digester process can reduce the total bacteria up to 1.49% (P>0.05) and decrease the total of Coliform bacteria up to 38.2% (P>0.05). High nutrient content and drop in number of total pathogenic bacteria and Coliform bacteria could create the biogas sludge from Bali cattle feces that was environmentally safe and directly used as an organic fertilizer to substitute chemical fertilizers
