DLAR Lab Submits Paper to IROS 2025: Energetics and Body Dynamics of High-Speed Quadrupedal Gaits

The DLAR Lab has submitted a paper titled “16 Ways to Gallop: Energetics and Body Dynamics of High-Speed Quadrupedal Gaits” to IROS 2025. The paper, authored by Yasser G. Alqaham, Jing Cheng, and Zhenyu Gan, systematically analyzes various galloping gaits, focusing on their energetic efficiency and body dynamics. The study investigates different galloping footfall sequences, exploring how the number of flight phases and the phase relationships between the front and rear legs impact energy consumption.

Using the A1 quadrupedal robot, the team employed hybrid dynamics and trajectory optimization to minimize the cost of transport across a range of speeds. The results demonstrate that the number of flight phases significantly influences energy efficiency, with galloping gaits with two flight phases showing the best performance at higher speeds. These findings offer valuable insights for improving the efficiency of quadrupedal robots and advancing high-speed locomotion strategies.

DLAR Lab Teams Attend BWSI Autonomous Racecar IAP 2024 in Boston

Two teams supervised by the DLAR Lab recently attended the BWSI Autonomous Racecar IAP 2024 in Boston, a part of the prestigious Beaver Works Summer Institute hosted by MIT. The six-week program, offered through Orange Works with support from ASPI and the College of Engineering and Computer Science, provides high school students with the opportunity to work on autonomous systems.

As part of the Autonomous Racecar Grand Prix, 15 New York high school students worked in teams to build, program, and race small remote-controlled vehicles on a challenging course. They gained hands-on experience coding navigation programs in Python and using advanced sensors to detect objects and navigate obstacles. This initiative is part of a broader effort by ASPI to expand autonomous systems education at Syracuse University, providing unique learning experiences for local teens.

The teams’ participation in this event reflects the DLAR Lab’s ongoing commitment to fostering the next generation of engineers and roboticists. We look forward to seeing how these students continue to innovate in the field of autonomous systems!

Yasser G. Alqaham submitted a conference paper to IROS on the Optimal Bounding Gaits of Quadrupedal Robots

Abstract— It is often overlooked by roboticists when designing locomotion controllers for their legged machines, that energy consumption plays an important role in selecting the best gaits for locomotion at high speeds or over long distances. The purpose of this study is to examine four similar asymmetrical quadrupedal gaits that are frequently observed in legged animals in nature. To understand how a specific footfall pattern will change the energetics of a legged system, we first developed a full body model of a quadrupedal robot called A1. And for each gait we created a hybrid system with desired footfall sequence and rigid impacts. In order to find the most energy efficient gait, we used optimal control methods to formulate the problem as a trajectory optimization problem with proper constraints and objective function. This problem was implemented and solved in a nonlinear programming framework called FROST. Based on the optimized trajectories for each gait, we investigated the values of cost of transport and the work done by all joints. Moreover, we analyzed the exchange of angular momentum in different components of the system during the whole stride cycle. According to the simulation results, bounding with two flight phases is likely to be the most energy efficient gait for A1 across a wide range of speed.
