robotics/854_bfbc7fe81559e716_465.txt | The great thing about the MXP program is that usually, the participants in these events like the STEM Expo have not had any experience with robotics, and they tend to perceive the concept as something that is beyond them. Being able to show kids that robotics is something that anyone, regardless of age, can understand ... |
robotics/b5f2ac11_9729.txt | 518 aluminum is a die-casting alloy that design engineers specify as an alternative to A380. It allows them to cast components with enhanced corrosion resistance that are easy to anodize and machine. Are you interested in 518's composition, applications, and... |

robotics/140b1462_10252.txt | The Kalman filter is efficient for sequential data processing on central processing units (CPUs), but in its original form it is inefficient on parallel architectures such as graphics processing units (GPUs). It is however possible to express the filter-update routine in terms of an associative operator using the formu... |

robotics/854_bfbc7fe81559e716_399.txt | Our biggest task is to smooth out the turntable both in code and build. The presets and smoothness of the turning need to be tested and improved. We also need to free up some room on the robot to allow the arm to swing around while the claw is fully retracted. The changes to the arm should be made pretty soon, to allow... |

robotics/854_bfbc7fe81559e716_390.txt | The belt was probably the most difficult part. What we needed to mount the belt was a piece that went up and over the rest of the slide then back down the other side, in order to have an attachment point for the end of the belt. This piece would be attached to the back of the top slide, and would be the highest point o... |
robotics/1266_94b562cd204cbb40_32.txt | However, most of the inconsistency is likely due to the difficulty of partial observability for RL. In particular, we noticed that with a DQN that is capable of (oracle) probing, such as the one in Figure 6, the inconsistencies are even greater, and they tend to perform worse, even though they have actions that should ... |
robotics/854_aeed479c586722c5_226.txt | On Thursday of last week I collected a new set of EGT data. These numbers, while better than the last set, are still not entirely smooth, but they are a starting point for revising the selection of GAMI injectors to match the new flow conditions with the reversed intake manifold. Because there is more scatter among the... |
robotics/07500f1e_11019.txt | Finally, quadrature magnetostrictive linear-displacement transducers (LDTs) are feedback encoder transducers designed to measure linear motion, rather than the rotational motion measured by encoders above. The analog position signal is developed from a current pulse sent down a magnetostrictive guide wire, interacting ... |
robotics/854_bfbc7fe81559e716_133.txt | I have reflected on my failures and am working hard to make sure I don't make similar mistakes in the future. It is also time for the rest of the team to reflect on our negligence. After analyzing our weak points, we are slowly working towards fixing the mistakes. As an example, Kenna was able to clean up our table so ... |
robotics/854_aeed479c586722c5_350.txt | Getting the batteries into the plane is the next problem. Their terminals are rectangular lead cages with a nut inside. The machine screw that engages this nut is a little too short, and I always end up having to shim one or two of the nuts up with cardboard to get them to engage with the screws. I noticed at AutoZone ... |
