robotics/1211_fe650460e2acb790_444.txt | Here we demonstrate the use of a new singlesignal surface electromyography (sEMG) brain-computer interface (BCI) to control a mobile robot in a remote location. Previous work on this BCI has shown that users are able to perform cursor-to-target tasks in two-dimensional space using only a single sEMG signal by continuou... |

robotics/14178_d4eee9ddd5e6add2_155.txt | The theory of stereo vision has been well understood for years, while the engineering challenge of creating a practical stereo-vision sensor has been formidable [21, 43, 44]. Example of commercially available stereo cameras are shown in figure 4.42. Basic case. First, we consider a simplified case in which two cameras ... |
robotics/1211_fe650460e2acb790_57.txt | A simple obstacle detection device, based upon an automobile parking sensor, was assessed as a mobility aid for the visually impaired. A questionnaire survey for mobility needs was performed at the start of this study. After the detector was developed, five blindfolded sighted and 15 visually impaired participants were... |

GPT-4 s ability to handle nuanced reasoning ensured that only the most challenging prompts remained. The prompt is shown as Figure 3 |
robotics/854_bfbc7fe81559e716_0.txt | Even though we were able to do a lot of work this day, we're slightly disappointed in our tiredness. Even though the RoboBisons had brought an entire field with them, we didn't really think about asking them to let us use it to practice. We were very exhausted, and with a half-still-sick Mr. Virani, we think we just we... |
robotics/cf1fc944_8949.txt | L293D contains two inbuilt H-bridge driver circuits. In its common mode of operation, two DC motors can be driven simultaneously, both in forward and reverse direction. The motor operations of two motors can be controlled by input logic at pins 2 amp; 7 and 10 amp; 15. Input logic 00 or 11 will stop the corresponding... |
robotics/84420734_10979.txt | Unfortunately, solving and simplifying this equation takes more vertical space than I'm willing to devote in this blog post, so we're just going to jump to the end result since this is really what's important for what we're doing. For the proof, check out Theorem 1 and Theorem 2 in this paper by Norbert Freier. It turn... |
robotics/b881bf00_10660.txt | Pioneering research on the perception of sounds at different frequencies was conducted by Fletcher and Munson in the 1930s. Their work led to a standard way of weighting measured sound levels within investigations of industrial noise and hearing loss. Frequency weightings have since been used within filter and controll... |
robotics/21338_ffcd46c10cd05485_391.txt | Diverse indicators of postural control in Humans have been explored for decades, mostly based on the trajectory of the center-of-pressure. Classical approaches focus on variability, based on the notion that if a posture is too variable, the subject is not stable. Going deeper, an improved understanding of underlying ph... |
