This paper builds on initial work on specifying robot motion using human-inspired motor programs. The existing method relies on a series of square wave torque pulses to actuate the robot. Using such pulses to produce motions with a robot will generate large peaks in absolute jerk — change in acceleration per unit time — which can damage the(More)
Maintaining consistent operational efficiency and productivity levels through effective and reliable workflow processes can be the key to businesses realising long-term profit margins. This can be difficult to achieve if the challenges that affect this dual paradigm are not fully understood. Where human input is an integral part of the business workflow,(More)
Supplement. Materials and methods Light sources—Ultraviolet light emitters were fit with dichroic glass filters, effectively eliminating any light visible to humans. There were no objects visibly fluorescing in the areas illuminated by the UV emitters. At night, the treated areas looked dark to human observers. To confirm that the trees were being lit by UV(More)
The functional organization of the human brain consists of a high degree of connectivity between interhemispheric homologous regions. The degree of homotopic organization is known to vary across the cortex and homotopic connectivity is high in regions that share cross-hemisphere structural connections or are activated by common input streams (e.g., the(More)
