Welcome to Learning to Run, one of the 5 official challenges in the NIPS 2017 Competition Track. In this competition, you are tasked with developing a controller to enable a physiologically-based human model to navigate a complex obstacle course as quickly as possible. You are provided with a human musculoskeletal model and a physics-based simulation environment where you can synthesise physically and physiologically accurate motion. Potential obstacles include external obstacles like steps or a slippery floor, along with internal obstacles like muscle weakness or motor noise. You are scored based on the distance you travel through the obstacle course in a set amount of time.

📝 Introduction

The objectives of this challenge are:

  • Bring Deep Reinforcement Learning to solve problems in medicine,
  • Promote open-source tools in RL research (the physics simulator, the RL environment, and the competition platform are all open-source),
  • Encourage RL research in computationally complex environments, with stochasticity and highly-dimensional action spaces.

Follow the instructions in the Getting Started guide in the Dataset section of the challenge and visit the github repo to get started!

🧪 Evaluation

Your task is to build a function f which takes the current state observation (a 41-dimensional vector) and returns the muscle excitations action (18-dimensional vector) in a way that maximises the reward. Your total reward is the position of the pelvis on the x-axis after the last iteration, minus a penalty for using ligament forces. Ligaments are tissues which prevent your joints from bending too much - overusing these tissues leads to injuries, so we want to avoid it. The penalty in the total reward is equal to the sum of forces generated by ligaments over the trial, divided by 1000. For details on evaluation, please refer to the Getting Started guide in the Dataset section of the challenge
