robotics/8895_80ceca0747858829_196.txt | As 3D printing becomes more and more common, homemade filament becomes easier to make. Traditionally, filament is made with large, industrial machines that can cost 10s of 1000s of dollars. Alternatively, DIY and homemade options can cost less than $1000, but at a much lower production rate and value. The purpose of th... |
robotics/14178_d4eee9ddd5e6add2_185.txt | Typically, there are missing contours, as well as noise contours, that do not correspond to anything of significance in the scene. The basic challenge of edge detection is visualized in figure 4.57. The top left portion shows the 1D section of an ideal edge. But the signal produced by a camera will look more like figur... |
robotics/1211_fe650460e2acb790_428.txt | The sensory, control, and operation systems of the 'MITy' Mars micro-rover are discussed. It is shown that the customized sun tracker and laser rangefinder provide internal, autonomous dead reckoning and hazard detection in unstructured environments. The micro-rover consists of three articulated platforms with sensing,... |
robotics/854_aeed479c586722c5_261.txt | The stainless steel fuel lines are all in place. It turned out to be possible, as I had hoped, to run them to the rear baffles so that they do not interfere with access to any part of the accessory case. They're quite difficult to bend, and once bent impossible to unbend, so I made each piece first out of aluminum tub... |
robotics/408d6039_0121.txt | Intelligent tutor systems (ITS) have been investigated for a long time and have been shown to outperform other computer aided instruction [ITSvsCAI]. Much work has been contributed via the framework provided by ASSISTments [online-edu-exp]. In particular, many experiments are run in the ASSISTments platform, and they i... |
robotics/854_bfbc7fe81559e716_42.txt | Tetrix: Tetrix is highly standardized in all dimensions, making the connections between parts easy to grasp for basic builders who haven’t developed a mental 3D idea of what they’re working towards. Tetrix kits don’t include electronics. However, their brackets, channels, and joints are very useful for making connectio... |

robotics/b633fe35_9572.txt | Stereo vision, also known as binocular vision, uses the same 3D camera principle as human eyes to determine the depth of objects-binocular disparity. Two camera lenses are placed at a certain baseline b distance from each other, positioned side by side, just like human eyes. When the stereo vision 3D camera is in opera... |
robotics/854_bfbc7fe81559e716_139.txt | One of the most important things I needed to put on was the Relic arm. After planning on it for the whole season, we finally finished it recently. I made a quick CAD model for it in a separate assembly. The servo horn with a custom made circular disk for holding spool was attached via co-incident constraints. The linea... |
robotics/854_aeed479c586722c5_460.txt | On the suggestion of Russ Hardwick I found small aluminum cable splices at a hardware store; these can be swaged with a pair of pliers, and while their tensile strength is not that of a proper aircraft swage, it is certainly enough for a trim system. These look as if they will increase the chain travel by 40% and the t... |
robotics/ba386e4d_10110.txt | Injection molding is a popular manufacturing process known for producing high-quality, precise, and consistent parts in large quantities. However, its high initial tooling costs and setup expenses can be prohibitive for small-scale productions or startups with limited budgets. Fortunately, several alternative manufactu... |
