Robot self-reconfigures using its own perception

A Cornell University led team has created modular robots that can perceive their surroundings, make decisions and autonomously assume different shapes in order to perform various tasks – although the robots remain error-prone. Given a high-level task specification, the intention is that a modular robot would autonomously explores an unknown environment, decided when and how ...

Self-clinching nuts and studs for automovtive thin high-strength steel

PEM has introduced self-clinching nuts and studs for the thin sheets of high-strength steel increasingly seen in automotive applications. Called SH self-clincing nuts and HFLH self-clinching studs are manufactured from hardened alloy. “Due to a lightweight design and reduced need for loose hardware such as washers, these fasteners can contribute to overall weight reductions in ...

Smart air con could stabilise power grid

Power grids could be stabilised by smart control of large air conditioning installations, without building occupants noticing, according to the US Oak Ridge National Laboratory. The lab has devised a method to control the heating and cooling systems of a large network of buildings for power grid stability, “which could allow utilities to harness the ...

Neural network IP aimed at SoCs processing complex speech

Cadence has introduced DSP intellectual aimed at neural network-based complex speech recognition on the local PCB, without the need for cloud-based services to do the heavy lifting. Resources are sufficient for far-field voice recognition, where the user is metres away from the microphone. Voice-controlled digital home assistants and automotive infotainment are intended applications. Why process ...
