Humanoids dance and thread needles as Japanese robotics developers look to outdo Chinese

Mechanical hands dexterous enough to thread a needle, childlike dancing robots and adult-sized ones to help with deliveries were on display Thursday as the Humanoids Summit Tokyo opened.

Louisiana's future coast will be 30 miles inland of where it is today. Locals can either start planning for the move now, or wait for Nature to force them to do it in a rush. Which do you think will happen?

⚑ Engineers don’t just measure power; they optimise it.

Whether you're designing compact IoT devices, high-performance electronics, EV battery systems, or next-gen energy solutions, power density is one of the most critical metrics determining efficiency, size, thermal performance, and innovation potential.

πŸ” Want a quick way to calculate and compare power density for your projects?

Try this free calculator from CircuitDigest:
https://circuitdigest.com/calculators/power-density-calculator

Higher power density can mean:
βœ… Smaller designs
βœ… Better performance per unit volume
βœ… Improved energy utilisation
βœ… Competitive product innovation

The future of electronics isn't just more powerβ€”it's more power in less space.

What application are you optimising for: IoT, EVs, renewable energy, robotics, or embedded systems?
