robotics/2885_33c4da2a7541fc56_154.txt | Since the term “video game” didn’t exist at the time, during the advertising campaign, the system was referred to as a “d-circuit electronic playground.” Catchy. So, what did the public think about such a device? The only form of visual home entertainment for most at the time was black-and-white TV. Suddenly, they woul... |
robotics/5116_2e518938aacdf0fd_36.txt | By contrast, a “force-aware” controller would be helpful when flying to the walls (in any direction), in a similar way as taking ground effect into account is useful for precision landing23, 9784–9790 (IEEE, 2019)."). We performed a preliminary study in simulation using model-predictive control and a Gaussian-processe... |
robotics/854_bfbc7fe81559e716_135.txt | As explained in a previous post, we were having many issues with git commits and fixing our errors in it. After a lot of the merging conflicts, we had to fix all the commits without exactly knowing what was being changed in the code. Part of the reason this was so hard was our lack of good naming conventions. Though we... |
robotics/1211_fe650460e2acb790_273.txt | The problems of facility location and the allocation of demand points to facilities are crucial research issues in spatial data analysis and urban planning. It is very important for an organization or governments to best locate its resources and facilities and efficiently manage resources to ensure that all demand poin... |
robotics/9aad8abe_9420.txt | As shown in Figure 1 , the main structure of the aerostatic bearing is a bearing pad, an orifice, a recess, and an air film. The airflow enters the recess through the orifice and then spreads around to form a high-pressure air film. The high-pressure air film can support the bearing load 20 , 21 , 22 . The diameter ... |
robotics/69bb0fae_6470.txt | Conventional path-planning approaches in the ROS navigation stack, such as the Dynamic Window Approach and Timed Elastic Band, primarily rely on manually designed heuristics or optimisation-based models. While these methods demonstrate stable performance in static environments, they face significant limitations in resp... |
robotics/5116_2e518938aacdf0fd_10.txt | We first observed that these effects substantially impact the capability of a drone in an air duct. In this experiment, a drone was controlled to hover inside and outside a 35-cm air duct, at the center. In both cases, its controller relies on an external, absolute position system (HTC Vive, see Methods). In free air, ... |
robotics/8895_80ceca0747858829_40.txt | This experiment dives into the antimicrobial efficiency of different herbal extracts compared to the pharmaceutical antibiotic Bacitracin against non-pathogenic *E. coli*. The main objective was to see whether or not herbal remedies could serve as viable alternatives to help fight against antimicrobial resistance (AMR)... |
robotics/caa52bc6_8001.txt | As a group identity, the above holds for all faithful representations, including the doublet (spinor representation), which is simpler. The same explicit formula thus follows straightforwardly through Pauli matrices; see the 2 2 derivation for SU(2). For the general n n case, one might use Ref. |
robotics/f8ea783a_10344.txt | The Kalman filter is a recursive estimator. This means that only the estimated state from the previous time step and the current measurement are needed to compute the estimate for the current state. In contrast to batch estimation techniques, no history of observations and or estimates is required. In what follows, the... |
robotics/a16c2a6b_0102.txt | This paper aims to address the challenge of hallucinations in Multimodal Large Language Models (MLLMs) particularly for dense image captioning tasks. To tackle the challenge, we identify the current lack of a metric that finely measures the caption quality in concept level. We hereby introduce HalFscore, a novel metric... |
robotics/854_bfbc7fe81559e716_749.txt | While the progress made with this version of the flywheel is substantial, it’s clear that the design still needs some minor updates. It's very unlikely that the new hub motor mount will be suspect to structural failures; however, we’re worried that it could result in the motor overheating as it's almost completely end.... |
robotics/8e5301b9_8550.txt | If x and y are the coordinates of the endpoint of a vector with the length r and the angle ϕ displaystyle phi with respect to the x -axis, so that x r cos ϕ textstyle x r cos phi and y r sin ϕ displaystyle y r sin phi , then the above equations become the trigonometric summation angle formulae : ... |
robotics/717bbbc4_7520.txt | This angular rate model is provided here for completeness, although is not used in this paper whose focus is that of the accelerometer bias error source and dealing with the removal of its impact. The study of the impact of rate errors on attitude determination as provided by the AHRS and their impact on navigation per... |
robotics/8f477766_8383.txt | We can also describe Spin(3) as isomorphic to quaternions of unit norm under multiplication, or to certain 4 4 real matrices, or to 2 2 complex special unitary matrices, namely SU(2). The covering maps for the first and the last case are given by H q H : q 1 w i x j y k z 1 2 y 2 2 z 2... |
robotics/854_aeed479c586722c5_808.txt | What is more difficult is determining the best orientation of the inlet. The range of fuselage incidences that are of interest is about 1 to 4 degrees. Unfortunately, I haven't been able to locate any information on the effect of misalignment on the pressure recovery of flush NACA scoops, though I have a faint recollec... |
robotics/bf3691c7_6369.txt | Local planning: DWA and TEB are commonly employed for real-time obstacle avoidance and trajectory optimisation. Among them, the Timed Elastic Band (TEB) algorithm is particularly well suited for environments with dynamic obstacles, as it models the robot s path as an elastic band subject to both spatial and temporal co... |
