• Abstract: Unmanned aerial vehicles (UAVs) operating in cluttered environments require accurate impact modeling to maintain stability post collisions. However, conventional contact models decouple linear and angular impulses, risking manifold inconsistency during rapid state transitions. This letter presents a dual quaternion reset map that resolves rigid-body impacts directly on the SE(3) manifold. By operating on the unified spatial twist (linear and angular velocities as a single dual entity), the proposed formulation is shown to be algebraically equivalent to the classical Newton impulse model while preserving manifold consistency during discrete state jumps. Building on this framework, a hybrid recovery controller is designed that couples linear and angular momentum to ensure strict energy dissipation across impacts. Hardware-in-the-loop benchmarks demonstrate a 24% reduction in execution latency compared to an optimized matrix-based implementation. High-fidelity MuJoCo simulations validate the controller's response to complex contact dynamics, with Monte Carlo trials showing a 56.3% reduction in post-impact root-mean-square error (RMSE) and a 61.1% decrease in peak kinetic energy compared to decoupled baseline controllers.

• First Steps: Latent-Space Control with Semantic Constraints for Quadruped Locomotion [73.37945453998134]
  Traditional approaches to quadruped control employ simplified, hand-derived models. This significantly reduces the capability of the robot since its effective kinematic range is curtailed. In this work, these challenges are addressed by framing quadruped control as optimisation in a structured latent space. A deep generative model captures a statistical representation of feasible joint configurations, whilst complex dynamic and terminal constraints are expressed via high-level, semantic indicators. We validate the feasibility of locomotion trajectories optimised using our approach both in simulation and on a real-worldmal quadruped.
