Retrospective Open-Vocabulary Memory for Long-Term Object Search
Jiaming Wang, Zhiwei Xue, Chen Jizhuo +2
Long-term object search requires learning where objects usually appear from repeated but uneven observations of a changing environment. We formulate retrospective open-vocabulary m…

VRA: Grounding Discrete-Time Joint Acceleration in Voltage-Constrained Actuation
Lingwei Zhang, Jiaming Wang, Tianlin Zhang +5
Discrete-time joint acceleration constraints are widely used to enforce position and velocity limits. However, under voltage-constrained electric actuators, kinematically admissibl…

Change-Robust Online Topological Memory for Long-Term Relocalization and Semantic Navigation
Jiaming Wang, Jizhuo Chen, Diwen Liu +4
Long-term semantic navigation requires a robot to reuse past observations after appearance and scene change, but semantic memories are only useful if the robot can relocalize into…
