robotics/1266_e26caa74eb27f4da_160.txt | Gaussian Processes (GPs) are widely seen as the state-of-the-art surrogate models for Bayesian optimization (BO) due to their ability to model uncertainty and their performance on tasks where correlations are easily captured (such as those defined by Euclidean metrics) and their ability to be efficiently updated online... |
robotics/854_bfbc7fe81559e716_502.txt | Despite putting in lots of effort in order to pull off a working autonomous before regionals, small and subtle issues that surfaced only during testing at the competition as well as various other small bugs with our autonomous routine prevented us from performing well on the field. Trying to write a full autonomous in ... |

This can easily be computed as a simple recursive update; however, to avoid... |
robotics/8b17cbcd_10036.txt | This part presents the simulation and experimental results of the neural network online training algorithm during path following and when adapting to the joint backlash. The results of the spiral tracking are illustrated in Figure 7 . Figure 8 shows the simulation and experimental tracking error in |

robotics/854_aeed479c586722c5_628.txt | After we collected our daughter from Williamstown, where she had spent the summer as an acting apprentice at the theater festival, we had an unbelievable amount of baggage to contend with. It barely fit in Dave Noland's SUV -- crossover, actually -- and just about filled M2, behind the front seats, to eye level. The th... |
robotics/d810b108_8450.txt | where for every direction in the base space, S n , the fiber over it in the total space, SO( n 1) , is a copy of the fiber space, SO( n ) , namely the rotations that keep that direction fixed. |
robotics/5116_532aad47262e4780_47.txt | Hi Saumya, I didn’t write the part of the code – that was from the original author, however, all that function does is copy the raw accelerometer, gyroscope and temperature data from the FIFO buffer on the MPU6050 chip into a data structure of type accel\_t\_gyro\_union inside the Arduino code. The bytes are copied ove... |
robotics/5effff7d_7096.txt | As illustrated in Figure 5, the fundamental principle of the artificial potential field method involves constructing a virtual gravitational potential field around the target location of the task. This field generates an attractive force that guides the manipulator toward the target. By constructing a virtual, repulsiv... |
robotics/854_aeed479c586722c5_813.txt | Forty-five minutes out of Livermore I observed the fuel flow to be rising while the peak EGT dropped. Smelling no fuel, I assumed that whatever was wrong it was not a fuel leak, and I continued on to Livermore. There I found that a loose B-nut on the fuel pressure line to the panel was allowing fuel to spray all over t... |
robotics/1211_fe650460e2acb790_15.txt | Concentric tube robots are thin, tentacle-like devices that can move along curved paths and can potentially enable new, less invasive surgical procedures. Safe and effective operation of this type of robot requires that the robot's shaft avoid sensitive anatomical structures (e.g., critical vessels and organs) while th... |
