Musbric builds reconfigurable muscle-powered robots with legos

MUSBRIC: LEGO-Compatible Pneumatic Muscle Bricks for Reconfigurable Musculoskeletal Robots

Abstract: Musculoskeletal robots combine compliant actuators with articulated skeletons, but exploring alternative configurations often requires repeated fabrication. We present MUSBRIC, a modular hardware platform and accompanying MuJoCo-based simulator for reconfigurable musculoskeletal robots. LEGO-compatible endcaps turn fiber-reinforced extensile pneumatic artificial muscles into reusable, plug-and-play muscle bricks that connect directly to standard LEGO components. Experimentally identified actuator behavior supports corresponding musculoskeletal simulations. An elbow-joint prototype validates load-dependent flexion and extension, showing that pulley-guided routing enables reversible motion and a mechanical stop stabilizes the straight posture. A robotic hand demonstrates compliant grasping and multi-joint construction. Matched hardware and simulation sweeps across 15 leg configurations demonstrate systematic exploration of attachment geometry, while a quadruped assembled from four legs demonstrates walking. Together, these demonstrations span mechanism analysis, configuration exploration, and functional robot construction within a single reconfigurable system. The hardware designs and simulation code will be released as open source soon to facilitate reproduction and further development.

The gist
Building robots with muscles that move like real limbs usually requires a lot of custom parts that are hard to change. The authors created MUSBRIC, a system using special artificial muscles that snap onto LEGO pieces, letting people quickly build and test different robot shapes. They also made computer simulations that match how these muscles behave in real life, so users can experiment without making new parts each time. The system includes examples like an arm joint, a robotic hand, and walking robot legs that show it can handle lots of different robot designs.

Embedded rust autopilot runs fast flight control on microcontroller

Cybflight: An Embedded Rust Autopilot for Aerial Robotics Research

Abstract: Bringing an aerial robotics method from simulation to flight should not require rebuilding a mature autopilot or adding a companion computer. Cybflight is an open-source embedded Rust research autopilot whose typed, replaceable interfaces connect hardware access, perception, state estimation, trajectory planning, and control. This modular development and compile-time optimization workflow is demonstrated with replaceable Rust implementations of model predictive contour-tracking control (MPCTC) and incremental nonlinear dynamic inversion (INDI) running on one STM32H743 without a companion computer. Using this configuration, the vehicle reaches 12.38 m/s during indoor flight, while an outdoor flight using global navigation satellite system (GNSS) position updates reaches 31.4 m/s. These flights show that running demanding estimation and nonlinear control entirely on a flight-controller microcontroller need not come at the expense of a modular autopilot structure.

The gist
Flying drones with advanced control often needs extra computers or complicated setups. The authors present Cybflight, a software system written in Rust that runs all the key autopilot tasks—like sensing, planning, and steering—directly on a small, low-power flight controller chip. This approach keeps the software modular and efficient, enabling fast indoor and outdoor flights without extra hardware. It shows that you can perform demanding drone control on simple devices while keeping the system flexible for research.
