Hi there!

My name is Peter Werner. I am a 3rd-year Ph.D. student in Prof. Daniela Rus’ lab at the Computer Science and Artificial Intelligence Laboratory (CSAIL) at MIT.

My research interests are broadly centered around Mathematics, Control Theory, Optimization, and Robotics. While my interests tend more towards theory and software, I have a deep appreciation for hardware. I find nothing more convincing than an actual hardware system executing an approach - there is no hiding or glossing over details.

Anyways, if I am not in the lab you can probably find me running along the Charles River, hiking in the Whites, skiing back home in Switzerland, or playing badminton. I also enjoy drawing inspiration from great engineers and inventors such as Wile E. Coyote (SuPeR gEnIouS), André Franquin’s Gaston, and Calvin from Calvin and Hobbes by Bill Watterson.

If you have any questions regarding my work or funny memes to share, feel free to contact me at {wernerpe} at {mit.edu}!

If you can guess what artist the favicon is referencing I will buy you a coffee =)

Approximating Robot Configuration Spaces with few Convex Sets using Clique Covers of Visibility Graphs

We propose an algorithmic appraoch to approximating robot configuration space with a small collection of convex sets. First, the algorithm constructs a visibility graph using sampling, then a small clique cover of the visibility graph is computed, and finally the cliques are inflated to full-dimensional polytopes that are collision free.

Certifying Bimanual RRT Motion Plans in a Second

We present an efficient method for certifying noncollision for piecewise-polynomial motion plans in algebraic reparametrizations of configuration space. Such motion plans include those generated by popular randomized methods including RRTs and PRMs, as well as those generated by many methods in trajectory optimization. Based on Sums-of-Squares optimization, our method provides exact, rigorous certificates of non-collision; it can never falsely claim that a motion plan containing collisions is collision-free.

Dynamic Multi-Team Racing: Competitive Driving on 1/10-th Scale Vehicles via Learning in Simulation

Autonomous racing is a challenging task that requires vehicle handling at the dynamic limits of friction. While single-agent scenarios like Time Trials are solved competitively with classical model-based or model-free feedback control, multi-agent wheel-to-wheel racing poses several challenges including planning over unknown opponent intentions as well as negotiating interactions under dynamic constraints. In this work, we address these challenges via self-play reinforcement learning to enable zero-shot sim-to-real transfer of highly dynamic policies.

Solving Continuous Control via Q-learning

We show that action discretization and value decomposition, enables us to scale and apply Q-learning to continuous control tasks. With bang-bang actions alone, the performance of this critic-only approach matches state-of-the-art continuous actor-critic methods when learning from features or pixels.

Certified polyhedral decompositions of collision-free configuration space

We extend prior work and now enable the computation of collision-free polytopes in a rational parametrization of robot configuration space for more general systems while only using convex optimization.
