Although bevel-gear robotic wrists are widely used in industrial manipulators due to their simple kinematics and low manufacturing cost, their gear trains function under rolling and sliding, the latter bringing about noise and vibration. Sliding is inherent to the straight teeth of the bevel gears of these trains. Moreover, unavoidable backlash introduces unmodeled dynamics, which mars robot pe...

In our study a robot was used to deliver objects for measurement into the Equator gauging system. To investigate robot’s manipulation influence on dimensional measurements, tasks were divided basic functions. Based these functions, nine different robot-manipulation scenarios defined, i.e., from zero full manipulation, two measuring (named Magnet and PKR) six characteristics (rectangular spheric...

This paper introduces novel air actuated spherical robot called ”RollRoller”. The RollRoller robot consists of two essential parts: tubes covered with a shell as a frame and mechanical controlling parts to correspond movements. The RollRoller is proposed to be high potential alternative for exploration and rescue missions robots because robot utlizing its locomotion via all possible deriving me...
