ReorientDiff: Diffusion Model based Reorientation for Object Manipulation

no code implementations28 Feb 2023 Utkarsh A. Mishra, Yongxin Chen

While certain goals can be achieved by picking and placing the objects of interest directly, object reorientation is needed for precise placement in most of the tasks.

Learning Representations for Pixel-based Control: What Matters and Why?

no code implementations15 Nov 2021 Manan Tomar, Utkarsh A. Mishra, Amy Zhang, Matthew E. Taylor

A wide range of methods have been proposed to enable efficient learning, leading to sample complexities similar to those in the full state setting.

Learning Control Policies for Imitating Human Gaits

no code implementations15 May 2021 Utkarsh A. Mishra

While skeletal models are driven with motor actuation, musculoskeletal models perform through muscle-tendon actuation.

Learning Linear Policies for Robust Bipedal Locomotion on Terrains with Varying Slopes

no code implementations4 Apr 2021 Lokesh Krishna, Utkarsh A. Mishra, Guillermo A. Castillo, Ayonga Hereid, Shishir Kolathaya

In this paper, with a view toward deployment of light-weight control frameworks for bipedal walking robots, we realize end-foot trajectories that are shaped by a single linear feedback policy.

Cycloidal Trajectory Realization on Staircase based on Neural Network Temporal Quantized Lagrange Dynamics (NNTQLD) with Ant Colony Optimization for a 9-Link Bipedal Robot

no code implementations2 Dec 2020 Gaurav Bhardwaj, Utkarsh A. Mishra, N. Sukavanam, R. Balasubramanian

For the task of climbing stairs by a 9-link biped model, a cycloid trajectory for swing phase is proposed in such a way that the cycloid variables depend on the staircase dimensions.

Planning Brachistochrone Hip Trajectory for a Toe-Foot Bipedal Robot going Downstairs

no code implementations2 Dec 2020 Gaurav Bhardwaj, Utkarsh A. Mishra, N. Sukavanam, R. Balasubramanian

Here, an adaptive trajectory planning algorithm is developed so that biped robots of varying link lengths, masses can climb down on varying staircase dimensions.
