Handling Robot SAMARA

08.06.2012
The handling robot system SAMARA (System Applying Momentum transmission for Acceleration of an end-effector with Redundant Axis) combines the advantages of heavy payloads and wide working space from Scara robots with the high acceleration of Delta robots. This is achieved by a new motion sequence that is characterized by a steadily rotation of the first axis. Thus it is necessary to accelerate only small masses, as the main part of energy used for the motion cycle is kept for the following cycle.<br><br>By applying such a redundant axis the kinetic energy can be retained in the robot links during a picking process and returned to the effector for speeding up the whole robot additional to the drives torques. As the nullspace movement ends with a stretched second and third link, acceleration of the effector must be regarded as an impulse, leading to acceleration of 20g. <br>

SAMARA allows solving “pick and place“ tasks even for heavy loads extremely fast, precise and energy-beneficial with only little space required for the SAMARA robot itself.<br> <br> <strong>Benefits</strong><br> <ul>

Im Focus: Freiburg researcher investigate the origins of surface texture

Most natural and artificial surfaces are rough: metals and even glasses that appear smooth to the naked eye can look like jagged mountain ranges under the microscope. There is currently no uniform theory about the origin of this roughness despite it being observed on all scales, from the atomic to the tectonic. Scientists suspect that the rough surface is formed by irreversible plastic deformation that occurs in many processes of mechanical machining of components such as milling.

Prof. Dr. Lars Pastewka from the Simulation group at the Department of Microsystems Engineering at the University of Freiburg and his team have simulated such...

Im Focus: Making the internet more energy efficient through systemic optimization

Researchers at Chalmers University of Technology, Sweden, recently completed a 5-year research project looking at how to make fibre optic communications systems more energy efficient. Among their proposals are smart, error-correcting data chip circuits, which they refined to be 10 times less energy consumptive. The project has yielded several scientific articles, in publications including Nature Communications.

Streaming films and music, scrolling through social media, and using cloud-based storage services are everyday activities now.

Im Focus: New synthesis methods enhance 3D chemical space for drug discovery

After helping develop a new approach for organic synthesis -- carbon-hydrogen functionalization -- scientists at Emory University are now showing how this approach may apply to drug discovery. Nature Catalysis published their most recent work -- a streamlined process for making a three-dimensional scaffold of keen interest to the pharmaceutical industry.

"Our tools open up whole new chemical space for potential drug targets," says Huw Davies, Emory professor of organic chemistry and senior author of the paper.

Im Focus: Quantum fluctuations sustain the record superconductor

Superconductivity approaching room temperature may be possible in hydrogen-rich compounds at much lower pressures than previously expected

Reaching room-temperature superconductivity is one of the biggest dreams in physics. Its discovery would bring a technological revolution by providing...
