robotics/3110_511d3b1626011606_1.txt | The advancement of robotic systems has revolutionized numerous industries, yet their operation often demands specialized technical knowledge, limiting accessibility for non-expert users. This paper introduces ROSA (Robot Operating System Agent), an AI-powered agent that bridges the gap between the Robot Operating Syste... |
robotics/e242021e_9313.txt | - 1904 - The tycoon George Westinghouse (most well known for being Nikola Tesla's financier during the infamous War of the Currents) receives a patent for a thrust bearing integrated into a vertical steam turbine. A prolific engineer and inventor in his own right, he leveraged the knowledge gained from his invention of... |
robotics/3205b8ae_6904.txt | While specifying tasks in the minimum-time formulation is straightforward, achieving successful learning can be challenging with complex real-world problems. One factor that impacts the difficulty of a minimum-time task is the exploration strategy. An implicit way of controlling exploration in RL is to invoke a environ... |
robotics/98d02f2b_9088.txt | In this example sketch, the for loops control the number of steps the stepper motor will take. The code within the for loop results in 1 step of the stepper motor. Because the code in the loop is executed 200 times (stepsPerRevolution), this results in 1 revolution. In the last two loops, the code within the for loop i... |
robotics/90282d45_7187.txt | Nonlinear optimization methods have been extensively used for robotic path planning as well, with plenty of attention being focused on evolutionary algorithms, especially Genetic Algorithms (GA), for point-to-point trajectories. This is due to several advantages they have over other methods: they allow for finding a gl... |

robotics/21338_ffcd46c10cd05485_240.txt | A computer program controls motors that drive translation stages in a metrology system that consists of a pair of two-axis cathetometers. This program is specific to Compumotor Gemini (or equivalent) motors and the Compumotor 6K-series (or equivalent) motor controller. Relative to the software supplied with the control... |
robotics/1211_fe650460e2acb790_420.txt | Performance for an obstacle circumvention task was assessed under conditions of visual, auditory only (using echolocation) and tactile (using a sensory substitution device, SSD) guidance. A Vicon motion capture system was used to measure human movement kinematics objectively. Ten normally sighted participants, 8 blind ... |
robotics/344_74e707900ee88d80_20.txt | One issue we have not yet addressed is how to define IK problems on a computer rather than mathematically. This is not so much of a problem with analytical methods --- you have spent hours deriving the solution and coding it up so you know exactly what the inputs and outputs need to be. But the strength of numerical me... |
