Reversible Hard Jaws

Reversible hard jaws from Dillon Manufacturing (Springfield, OH) are suitable for ID and OD workholding. The jaws are designed to hold a specific range of part sizes and are usually used for first operation workholding. They are available in serrated, Acme Key, square key, and tongue-and-groove styles to fit all brands of chucks. These single- or two-step jaws feature diamond-shaped serrations for gripping and parts locating. The hard jaws are manufactured of case-hardened 8620 steel that is coated with black oxide for corrosion resistance, and feature ground locating surfaces.

Cable Retraction System

The triflex® RSE pullback system from igus (East Providence, RI) uses a simple linear retraction without bends, fiber rods, or rollers. The system consists of a drylin® linear guide with carriage, elastic cord for retraction, fastening plates for connection to a variety of robot types, mounting bracket without strain relief for the respective e-chain size, and gliding feed-through for the respective e-chain size. The product is available for triflex sizes from 60-125, all of which can be mounted on one system. The linear system has fewer deflection points, and consequently provides better process reliability for laser light cables and supply hoses.

Collaborative Robot

Kawasaki Robotics (Wixom, MI) introduced the duAro collaborative robot. The dual-arm, horizontal articulated robot can safely collaborate with humans in work operations due to its low-power motors, soft body, speed, and shared work zone monitoring. The single-axis configuration provides independent arm operation with ±0.05 mm repeatability and a payload capacity of 2 kg per arm. Use of both arms in coordinated movements increases the robot payload capacity to 4 kg. The base of the robot is on wheels and accommodates the controller. The robot is designed to be installed in a single-person space, so it can be deployed without modifications to the assembly or manufacturing line. A direct teach function lets users teach the robot tasks by hand-guiding its arms, or the robot can be programmed using a PC or tablet terminal by entering numerical values indicating the direction and distance of each movement.

Collaborative Robot

Rethink Robotics (Boston, MA) introduced Sawyer, a smart collaborative robot designed to execute machine tending, circuit board testing, and other precise tasks. The robot modifies its behavior to respond to changing and unexpected conditions on the plant floor. The robot weighs 19 kg (42 lbs.), and features 7 degrees of freedom with a 1260-mm reach that can maneuver into the tight spaces and varied alignments of work cells designed for humans. Its compliant motion control allows it to “feel” its way into fixtures or machines, even when the position varies slightly. The robot’s precision is ±.1 mm in semi-structured environments. An embedded vision system uses a head camera for wide-view applications and a Cognex camera in its wrist. The robot features a face screen to help it communicate with co-workers, and a train-by-demonstration user interface.

Part Positioners

Yaskawa Motoman (Dayton, OH) expanded its line of RM2 ferris wheel-style robotic part positioners. The positioners have two servo-driven trunnion/station axes on opposite sides of a central “sweep” axis. One station is positioned in front of one to four welding robots, while the other station is outside the robot envelope where the operator loads/unloads parts. The 180° sweep axis rotates the stations over/under the central axis between the robot(s) and the operator. Slim-Line positioner models have a 17% smaller width than standard positioners, and are available with 755-kg and 1,255-kg payload capacities. Extra-large-capacity positioners were designed to provide higher payloads and turning diameters in a reduced profile, and feature 1,555-kg and 2,355-kg payload capacities.

Are you optimistic about AI possibilities?

This week's Question: Today's featured INSIDER story demonstrated a new achievement in artificial intelligence. According to a recently released Stanford University report developed by a standing group of AI scientists, the ability for robots to be self-determined and concerned with their own longevity is a leap far beyond current interest or capabilities. "I'm highly optimistic that artificial intelligence technologies are going to improve the world,” said lead author of the report and University of Texas computer scientist Peter Stone. The researchers cited autonomous transportation, healthcare data computation, and crime prevention as areas that may benefit from the use of AI. What do you think? Are you optimistic about AI possibilities?
