Tool Helps Design Soft Robots That Can Bend and Twist

Designing a soft robot to move organically — to bend like a finger or twist like a wrist — has always been a process of trial and error. Now, researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences and the Wyss Institute for Biologically Inspired Engineering have developed a method to automatically design soft actuators based on the desired movement.

Chemical Compatibility With Hospital Disinfectants and Oncology Drugs

In a hospital environment, the need to mitigate risks and enhance patient safety and comfort has significantly increased the demand for high-performing plastics with improved chemical resistance. This white paper presents results from screening studies measuring clear thermoplastics’ chemical compatibility with various medical disinfectants, oncology drug carrier solvents, and actual oncology drugs. As compatibility becomes more complex, it’s apparent that Eastman Tritan™ copolyester offers clear advantages.

The Basics of Encoder Selection

Positioning: Resolution and AccuracyAn application’s required positioning resolution dictates the choice of encoder resolution. A well-tuned system can maintain the position within one encoder state (quadcount). Therefore, the encoder resolution in quadcounts (states) should at least correspond to the maximum permissible positioning error. Depending on the response time of the system, a higher encoder resolution should be chosen for the controller to detect deviations faster and counteract quicker.

Branimir Blagojevic, Technologist, Goddard Space Flight Center, Greenbelt, MD

During his time with former employer Science and Engineering Services, LLC, Branimir Blagojevic helped build a remote-sensing device that detected biological agents. The technology, originally made for the Department of Defense (DoD), may soon find a place on Mars. Blagojevic currently leads the development of the Bio-Indicator Lidar Instrument (BILI), a device that could be used to spot organic molecules and signs of life on Mars.
