Multi-contact loco-manipulation trajectories for the ANYmal robot with a 6-DoF Arm
<p>Loco-manipulation planning skills are pivotal for expanding the utility of robots in everyday environments. These skills can be assessed based on a system's ability to coordinate complex holistic movements and multiple contact interactions when solving different tasks. However, existing approaches have been merely able to shape such behaviors with hand-crafted state machines, densely engineered rewards, or pre-recorded expert demonstrations. Here, we propose a minimally-guided framework that automatically discovers whole-body trajectories jointly with contact schedules for solving general loco-manipulation tasks in pre-modeled environments. The key insight is that multi-modal problems of this nature can be modeled within the context of integrated Task and Motion Planning (TAMP), resulting in a tractable bilevel optimization formulation. An effective bilevel search strategy is achieved owing to the fusion of domain-specific rules with the well-established strengths of different planning techniques: trajectory optimization and informed graph search, coupled with sampling-based planning. We showcase emergent behaviors for a quadrupedal mobile manipulator exploiting both prehensile and non-prehensile interactions to perform real-world tasks such as opening/closing heavy dishwashers and traversing spring-loaded doors. These behaviors are also deployed on the real system using a two-layer whole-body tracking controller.</p>

All-atom MD trajectory TOCL:POPC (20%), 50mM KCl
<p>~400-ns MD simulation of a lipid bilayer, which monolayer was composed of 44 POPC (1-Palmitoyl-2-oleoylphosphatidylcholine) molecules and 6 TLCL (tetra-linoeoyl-cardiolipin) molecules. The background electrolyte is KCl; these ions were added in that amount, which imitates 50-mM ionic force in the bulk. The water amount is large (more than 140 water molecules per lipid), allowing it to equilibrate the electric double layer at a relatively low ionic force.</p> <p>TIP3P water model and CHARMM36 force field were used; the double-deprotonated form of cardiolipin was used (TLCL2). Production simulation was performed with MD integrator (2-fs step, bonds to hydrogen atoms were constrained), Nose-Hoover thermostat (303K, 1-ps time constant) and Parinello-Rahman semi-isotropic barostat (5-ps time constant, water compressibility). PME was used for electrostatics; cut-off radii were set to 1.2 nm. VDW switch radius was set to 1.0 nm.</p> <p>Resulting trajectories deposited:</p> <ul> <li><strong>COMBINED-50ps.trr</strong> [373 ns length, 50-ps step, with velocities]</li> <li><strong>COMBINED-10ps-100ns.trr</strong> [last 100 ns, 10-ps step, with velocities]</li> <li><strong>COMBINED.edr</strong> [373 ns length, 2-ps step]</li> </ul> <p>The additional ZIP archive contains intermediate TPR and MDP files and a force field folder.</p>

Scanning gate microscopy of non-retracing electron-hole trajectories in a normal-superconductor junction - code
<p>We theoretically study the Scanning Gate Microscopy (SGM) of the electron and hole trajectories in a Normal-Superconductor (NS) interface where a Quantum Point Contact (QPC) is embedded. In the zero bias case, electrons after getting Andreev reflected as a hole from the NS interface, have a similar wave vector, which causes the self-interference pattern in the SGM conductance plots. For the nonzero bias case, electrons and holes have different wave vectors. As a result, a disturbed and branched flow SGM conductance map is observed. Also by plotting the probability currents, we can clearly see the difference in two cases. The code contains all of these calculations.</p>
