New hybrid hexapod has nanometer-level precision

The Hybrid Hexapod from ALIO Industries has revolutionized 6D motion and redefined the role of motion control in applications that need flatness and straightness of motion plus stiffness, such as machining and bonding. It uses a tripod parallel kinematics structure to deliver Z plane and tip/tilt motion, integrated with a monolithic serial kinematic structure for XY motion. A rotary stage integrated into the top of the tripod (or underneath it) provides 360-degree continuous yaw rotation. Applications include optical, semiconductor, manufacturing, metrology, laser processing, and micro-machining.

Gearboxes for electric motors from Rexroth: a driving force for electrification

As part of its new, extensive eLION platform for the electrification of mobile working machines, Bosch Rexroth has developed spur gearboxes that vehicle manufacturers can use to unlock the full potential of new electric motors. The one- and two-speed gearboxes are installed in the central section of the vehicle and pool the energy in order to drive up to two axles with just one motor. The clever integration of essential components is evidence of the wealth of practical know-how that was drawn on throughout the development process.

The new reliable actuator for heavy loads

Bosch Rexroth's electro-mechanical cylinders (EMCs) are now available in a high-force, high-precision, low-maintenance version: the EMC-HP. Designed for loads up to 100 kN, the new actuators are robust and compact. Based on the reliable planetary screw drive, users will benefit from impressive continuous power -- even under harsh conditions -- thanks to both the new oil-bath lubrication and optional water cooling directly on the screw itself. A fully digital process, from selection to ordering, shortens engineering time.

Lead-foot police: Ford testing geofencing tech in Europe that automatically reduces vehicle speed

Many cities and towns limit speeds around schools, hospitals, and shopping areas. Seeing the signs, however, can depend on how visible they are, whether they are concealed by branches, or maybe surrounded by a cluster of other signs.

Now, Ford is testing connected vehicle technology using geofencing (a virtual geographical boundary) that could one day do away with the need for speed limit signs completely, as well as potentially making streets safer for other road users and pedestrians. Ford says its Geofencing Speed Limit Control system could help drivers avoid inadvertently incurring speeding fines and improve roadside appearances.

Driver assistance technologies such as Ford's Intelligent Speed Assist and Adaptive Cruise Control with Stop & Go already help ensure drivers do not exceed speed limits. Ford says its Geofencing Speed Limit Control system is potentially more flexible and effective than on-board systems, and could, in the future, be applied to Ford commercial and passenger vehicles.

Researchers are using two Ford Pro vehicles to analyze the impact of speed limiting in terms of improving traffic flow and reducing the risk of accidents. Testing with the all-electric Ford E-Transit vans extends to all 30-km/h zones in the center of Cologne, Germany, as well as in selected 50-km/h and 30-km/h zones elsewhere in the city.

The 12-month trial builds on other recent Ford research projects that aim to help improve road safety, including connected traffic-light tech that could automatically go green to offer clearer routes for ambulances, fire engines, and police vehicles, and the use of specific speakers inside the vehicle to alert drivers to the direction from which people and objects are approaching.

The geofencing trial is the result of a collaboration between the Ford City Engagement team, city officials in Cologne and Aachen, Germany, and Ford software engineers in Palo Alto, CA. Together with colleagues in Aachen, the Palo Alto engineers developed technology that connects the vehicle to the geofencing system for GPS tracking and data exchange.

The driver receives the information via the dashboard display cluster, with the new speed limit flashing below the current speed. The vehicle automatically reduces speed in line with the geofenced zone. The driver can override the system and deactivate the speed limit control at any time.

In the future, Ford's Geofencing Speed Limit Control system could enable drivers to set their own geofencing zones at speeds as low as 20 km/h, including at depots and private facilities. Speed limits could also be set dynamically to take into account local hazards, temporary road works, and the time of day.

The trial in Germany runs until March 2023.
