By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News Daily News-Research findings on Robotics are disc ussed in a new report. According to news reporting from Nanjing, People's Republ ic of China, by NewsRx journalists, research stated, "PurposeStiffness adjusting ability is essential for soft robotic arms to perform complex tasks. A soft sta te enables dexterous operation and safe interaction, while a rigid state enables large force output or heavy weight carrying." Financial supporters for this research include National Natural Science Foundati on of China (NSFC), Natural Science Foundation of Jiangsu Province. The news correspondents obtained a quote from the research from Nanjing Tech Uni versity, "However, making a compact integration of soft actuators with powerful stiffness adjusting mechanisms is challenging. This study aims to develop a pist on-like particle jamming mechanism for enhanced stiffness adjustment of a soft r obotic arm has two pairs of differential tendons for spatial bending, and a jamming co re consists of four jamming units with particles sealed inside braided tubes for stiffness adjustment. The jamming core is pushed and pulled smoothly along the tendons by a piston, which is then driven by a motor and a ball screw mechanism. FindingsThe tip displacement of the arm under 150 N jamming force and no more th an 0.3 kg load is minimal. The maximum stiffening ratio measured in the experime nt under 150 N jamming force is up to 6-25 depends on the bending direction and added load of the arm, which is superior to most of the vacuum powered jamming proposed robotic arm makes an innovative compact integration of tendon-driven r obotic arm and motor-driven piston-like particle jamming mechanism."
