Transmission

The Harmonic Drive is a key part of countless robotic applications. Incredibly simple yet quite odd to watch, this gear system is extremely precise with an impressive torque-to-weight ratio, even if it does wobble. So how does it work?

Scientists at the University College London have set a new world record in wireless data transmission speeds, sending a blistering 938 Gigabits per second (Gbps) over the air through a combo of radio and light technology.

KTM’s all-new Automated Manual Transmission (AMT) is rolling out on the upcoming 1390 Super Adventure, and the company says it'll change the way we ride motorcycles. It comes with a P–N–1–2–3–4–5–6 gear sequence – and of course, no clutch lever.

DJI, which nearly everyone knows as the drone company, made the jump into the electric mountain bike (eMTB) sector this year with the DJI Avinox Drive System. We just wanted to show you the clever inner workings of the setup, which brings some unique features to the table.

NASA’s Psyche spacecraft, farther away than the Sun, has sent data through a laser over a record-breaking distance, and done so even faster than expected. The breakthrough could help establish high-speed communications with human colonies on Mars.

Everybody wants a faster internet connection, and now engineers in Japan have shattered the record for data transmission. The team managed to transmit more than 20 times the global internet traffic per second through a single optical fiber.

The Orbit Drive promises an ebike transmission, built into the motor housing, that lasts for thousands of miles without maintenance, boosts efficiency and range, allows regenerative braking, and comes out lighter than most ebike drive systems.

A small satellite developed by MIT engineers has set a new record for data transmission between a satellite and Earth. The TeraByte InfraRed Delivery (TBIRD) system used a laser to beam huge amounts of data at up to 100 gigabits per second.

Engineers have set a new speed record for data transmission through a standard diameter optical fiber. By beaming 55 “modes” of signals down a single-core optical fiber, the team was able to transmit at a data rate of 1.53 petabits per second.

Researchers in Japan have clocked a new speed record for data transmission – a blistering 1.02 petabits per second (Pb/s). Better yet, the breakthrough was achieved using optical fiber cables that should be compatible with existing infrastructure.

New research published in Nature Medicine has found COVID-19 vaccination can reduce a person’s infectious viral load. The study compared the infectiousness of different SARS-CoV-2 variants in vaccinated and unvaccinated subjects.

The first bikes using Valeo's smart ebike system will roll off production lines within months. Fourteen manufacturers have signed on to begin using this high-torque integrated powertrain, with its built-in 7-speed automatic transmission and belt drive.
