Repository of problems worth solving
World Solve is a public institutional repository for identifying real unresolved problems across science, society, health, governance, economics, and local systems. Each entry is intended to be citable, inspectable, and actionable.
Publicly citable
Every problem has a stable citation code for reference and discussion.
Filtered by relevance
Search by category, geography, status, and keywords.
Builder-oriented
Use the repository to find startup ideas, policy leads, and research agendas.

Remote and mountainous areas remain costly to connect to national grids, leaving villages without reliable power. Off-grid solar mini-grids tailored to difficult terrain could close this gap faster.

Landers currently depend on pre-mapped terrain, which leaves them vulnerable to boulders, unexpected slopes, and dust plumes during touchdown. Ultra-fast optical-LiDAR terrain-relative navigation is needed for safe pinpoint landing.

Because operators on Earth must check every step, rovers cover only meters per day on distant worlds. Fully autonomous, vision-guided AI navigation system operating locally on edge hardware is needed.

Laying physical fiber cable across mountains, deserts, or widely scattered rural populations is often prohibitively expensive relative to the number of people served. Finding cost-effective alternatives for these hard-to-reach areas remains unresolved.

Even the best robots struggle with uneven terrain, sudden obstacles, or tasks requiring fine motor control that animals handle instinctively. Closing this gap would open up robotics for disaster response, farming, and elder care.
