sim2real.world Weekly summaries of robotics papers that move from simulation to a real robot. https://sim2real.world/ 2026-10-31T09:00:00Z sim2real.world Week 44: catching, a slope, and a surgical handoff https://sim2real.world/e/2026-w44/ 2026-10-31T09:00:00Z Three papers that make a policy survive hardware. None published the number that would let you compare them. Each paper fixes a different part of the problem. The catching hand trusts nothing about contact. The rover distrusts the ground. The surgical robot invents the handoffs it needs.
