Mobile exploration is a longstanding challenge in robotics, yet current methods primarily focus on active perception instead of interaction, limiting the robot's ability to interact with and fully explore its environment. Existing robotic approaches via interaction are often restricted tabletop scenes, neglecting unique challenges posed by mobile exploration, such as large spaces, complex action diverse object relations. In this work, we introduce 3D relational graph that encodes relations...
Abstract Salt stress is a major environmental factor limiting crop growth and productivity. Here, we show that Salt‐Tolerant Gene 1 ( ZmSTG1 ) contributes to salt tolerance by maintaining photosystem activity in maize. encodes an endoplasmic reticulum localized protein retrotransposon insertion the promoter region causes differential expression levels maize inbred lines. Overexpression of improved plant vigor, knockout weakened under normal conditions. Transcriptome metabolome analyses...
Drought and salt stress are major abiotic that inhibit plants growth development, here we report a plasma membrane intrinsic protein ZmPIP1;1 from maize identified its function in drought tolerance Arabidopsis. was localized to the endoplasmic reticulum protoplasts. Treatment with PEG or NaCl resulted induced expression of root leaves. Constitutive overexpression transgenic Arabidopsis enhanced compared wild type. A number responsive genes involved cellular osmoprotection were up-regulated...
We present successful control strategies for dynamically stable robots that avoid low ceilings and other vertical obstacles in a manner similar to limbo dances. Given the parameters of mission, including goal obstacle dimensions, our method uses sequential composition IO-linearized controllers applies stochastic optimization automatically compute best controller gains references, as well times switching between different controllers. demonstrate this system through numerical simulations,...

In this work, the falling problem is formulated using optimal where we seek impulse on impact with ground, subject full-body dynamics and constraints of robot joint space. extend previous work domain by numerically approximating resulting control, open-loop solving equivalent nonlinear programming problem. Compared results optimization, proposed...
Optimizing the control of articulated mobile robots leads to emergent behaviors that improve effectiveness, efficiency and stability wheeled humanoids dynamically stable manipulators. Our simulated results show optimization over target pose, height parameters in effective strategies for standing, acceleration deceleration. These system performance by orders magnitude existing controllers. This paper presents a simple controller robot motion an method choosing its parameters. By using...
This paper describes our successful implementation of a robot that autonomously and strategically removes multiple blocks from an unstable Jenga tower. We present integrated strategy for perception, planning control achieves repeatable performance in this challenging physical domain. In contrast to previous implementations, we rely only on low-cost, readily available system components use strategic algorithms resolve uncertainty. three-stage planner block extraction which considers...
Traversing terrain with good traction is crucial for achieving fast off-road navigation. Instead of manually designing costs based on features, existing methods learn properties directly from data via self-supervision to automatically penalize trajectories moving through undesirable terrain, but challenges remain in properly quantifying and mitigating the risk due uncertainty learned models. To this end, we present evidential autonomy (EVORA), a unified framework uncertainty-aware model plan...

Carbonic anhydrase (CA) catalyzes the reversible CO2 hydration reaction that produces bicarbonate for phosphoenolpyruvate carboxylase (PEPC). This is initial step transmitting signal in C4 photosynthesis. However, it remains unknown whether maize (Zea mays L.) CA gene, ZmCA4, plays a role photosynthesis process. In our study, we found ZmCA4 was relatively highly expressed leaves and localized chloroplast plasma membrane of mesophyll protoplasts. Knock-out reduced activity, while...
