We just launched https://robotbenchmark.net to allow everyone to program simulated robots online with Python. Video announcement: https://www.youtube.com/watch?v=S0k0cJb_Mus Robotbenchmark offers a series of robot Python programming challenges that address various topics across a wide range of difficulty levels, from middle school to PhD. Users don't need to install any software on their computer, cloud-based 3D robotics simulations run on a web page. They can learn programming by writing Python code to control robot behavior. The performance achieved by users is recorded and displayed online, so that they can challenge their friends and show off their skills at robot programming on social networks. Everything is designed to be extremely easy-to-use, runs on any computer, any web browser, and is totally free of charge. I believe his tool has a great potential for teaching Python, as 3D simulated robots are very appealing to students. We would love to receive your feedback at info@robotbenchmark.net. Cheers, -Olivier
