&lt;p>In this paper, we address the Perception&amp;ndash;Constrained Model Predictive Control (PCMPC) and state estimation problems for quadrotors with cable suspended payloads using a single camera and Inertial Measurement Unit (IMU). We design a receding&amp;ndash;horizon control strategy for cable suspended payloads directly formulated on the system manifold configuration space SE(3)xS^2. The approach considers the system dynamics, actuator limits and the camera&amp;rsquo;s Field Of View (FOV) constraint to guarantee the payload&amp;rsquo;s visibility during motion. The monocular camera, IMU, and vehicle&amp;rsquo;s motor speeds are combined to provide estimation of the vehicle&amp;rsquo;s states in 3D space, the payload&amp;rsquo;s states, the cable&amp;rsquo;s direction and velocity. The proposed control and state estimation solution runs in real-time at 500 Hz on a small quadrotor equipped with a limited computational unit. The approach is validated through experimental results considering a cable suspended payload trajectory tracking problem at different speeds.&lt;/p></description></item><item><title>Efficient Trajectory Library Filtering for Quadrotor Flight in Unknown Environments</title><link>https://lguanrui.github.io/conference/viswanathan-2020-efficient/</link><pubDate>Wed, 01 Jan 2020 00:00:00 +0000</pubDate><guid>https://lguanrui.github.io/conference/viswanathan-2020-efficient/</guid><description/></item><item><title>ModQuad-DoF: A Novel Yaw Actuation for Modular Quadrotors</title><link>https://lguanrui.github.io/conference/gabrich-2020-modquad/</link><pubDate>Wed, 01 Jan 2020 00:00:00 +0000</pubDate><guid>https://lguanrui.github.io/conference/gabrich-2020-modquad/</guid><description/></item><item><title>Observability-Aware Trajectories for Geometric and Inertial Self-Calibration</title><link>https://lguanrui.github.io/conference/bohm-2020-observability/</link><pubDate>Wed, 01 Jan 2020 00:00:00 +0000</pubDate><guid>https://lguanrui.github.io/conference/bohm-2020-observability/</guid><description/></item><item><title>ModQuad-Vi: A vision-based self-assembling modular quadrotor</title><link>https://lguanrui.github.io/conference/li-2019-modquad/</link><pubDate>Tue, 01 Jan 2019 00:00:00 +0000</pubDate><guid>https://lguanrui.github.io/conference/li-2019-modquad/</guid><description/></item><item><title>ModQuad: The flying modular structure that self-assembles in midair</title><link>https://lguanrui.github.io/conference/saldana-2018-modquad/</link><pubDate>Mon, 01 Jan 2018 00:00:00 +0000</pubDate><guid>https://lguanrui.github.io/conference/saldana-2018-modquad/</guid><description/></item></channel></rss>
