About Me

Programmer & Roboticist

I’m Jun Zeng (曾俊). My work spans robotics, artificial intelligence and autonomous systems — optimal control, nonlinear optimization, motion planning, trajectory generation, reinforcement learning and machine learning. I build algorithms at the intersection of decision-making, learning and physical systems, so that robots and autonomous vehicles can operate safely and intelligently in complex real-world environments.

I’m currently the Chief Technology Officer of Cyan Robotics in Shanghai, leading Amoo, an embodied companion robot, from research prototype to consumer product. I received my Ph.D. from the Hybrid Robotics Group at UC Berkeley under Prof. Koushil Sreenath, where I worked on model-based optimization, control and learning for aerial and legged robots.

I’m always glad to have technical discussions and to build new connections — feel free to reach me through the links below.

Experience

Cyan Robotics 2025 – Present
Chief Technology Officer — Shanghai, China

Own the technology strategy, roadmap and system architecture for Amoo, an embodied companion robot. Lead a multidisciplinary team across the full robotics and AI stack — hardware-software integration, robot control and autonomous behaviors through foundation models and LLM-based intelligence.

Cruise LLC 2022 – 2025
Senior AI/ML Scientist — San Francisco, CA

Trajectory generation and large driving models for autonomous vehicles: unified reactive motion planning and control, non-convex trajectory generation solvers, and constraint enforcement inside large behavior models across pretraining, post-training and deployment.
