DTEA: A Dual-Topology Elastic Actuator Enabling Real-Time Switching Between Series and Parallel Compliance
Vishal Ramesh, Aman Singh, Shishir Kolathaya
Series and parallel elastic actuators offer complementary but mutually exclusive advantages, yet no existing actuator enables real-time transition between these topologies during o…
A Co-Design Framework for High-Performance Jumping of a Five-Bar Monoped with Actuator Optimization
Aastha Mishra, Aman Singh, Shishir Kolathaya
The performance of legged robots depends strongly on both mechanical design and control, motivating co-design approaches that jointly optimize these parameters. However, most exist…
A Co-Design Framework for Energy-Aware Monoped Jumping with Detailed Actuator Modeling
Aman Singh, Aastha Mishra, Deepak Kapa +2
A monoped's jump height and energy consumption depend on both, its mechanical design and control strategy. Existing co-design frameworks typically optimize for either maximum heigh…
COMPAct: Computational Optimization and Automated Modular design of Planetary Actuators
Aman Singh, Deepak Kapa, Suryank Joshi +1
The optimal design of robotic actuators is a critical area of research, yet limited attention has been given to optimizing gearbox parameters and automating actuator CAD. This pape…
Comparison between External and Internal Single Stage Planetary gearbox actuators for legged robots
Aman Singh, Deepak Kapa, Prasham Chedda +1
Legged robots, such as quadrupeds and humanoids, require high-performance actuators for efficient locomotion. Quasi-Direct-Drive (QDD) actuators with single-stage planetary gearbox…
