Terrain Classification for the Spot Quadrupedal Mobile Robot Using Only Proprioceptive Sensing
Quadrupedal mobile robots can traverse a wider range of terrain types than their wheeled counterparts but do not perform the same on all terrain types. These robots are prone to undesirable behaviours like sinking and slipping on challenging terrains. To combat this issue, we propose a terrain classifier that provides information on terrain type that can be used in robotic systems to create a traversability map to plan safer paths for the robot to navigate. The work presented here is a terrain …

Ground calibration plans for the AXIS high speed camera
The Advanced X-ray Imaging Satellite (AXIS), an astrophysics NASA probe mission currently in phase A, will provide high-throughput, high-spatial resolution X-ray imaging in the 0.3 to 10 keV band. We report on the notional ground calibration plan for the High Speed Camera on AXIS, which is being developed at the MIT Kavli Institute for Astrophysics and Space Research using state-of-the-art CCDs provided by MIT Lincoln Laboratory in combination with an integrated, high-speed ASIC readout chip fr…

"The Marshall Plan did help rebuild Europe. The Civil Rights Movement did end Jim Crow. Smallpox was eradicated through an international coordination effort. The Montreal Protocol did address the ozone hole. Are these perfect success stories? No, they all happened through a series of shitty compromises, through flawed execution and with unintended consequences." <-- Thanks Joan!
