Cornell Aeronautical Labs Man-Amplifier (1961) (via cyberneticzoo)

Cornell Aeronautical Laboratories of Buffalo, New York  were producing papers on Man Amplifiers as early as 1960. In 1961 they received a grant to explore these ideas. Initial work was on an exoskeleton, and later work on a mock-up.

There are some initial concepts one has to be aware of in understanding Man Amplifiers.

Typically there is a master component, and a slave component. In other teleoperated manipulators, they are physically and spatially separate.  In the exoskeleton man-amplifier, they are together. In the Cornell Man-Amplifier, one of the problems encountered was the close proximity of the control harness (master) with the powered exoskeleton.

You will often see the phrase “bilateral force feedback with force reflection”.

Bilateral force feedback meaning that both the master and slave units have common joints and position and force information can be transmitted in both directions (from operator to task and vice versa).  Force feedback is when, for example, an obstacle is met with some resistance, that the resistance is felt back at the master. E.g. if you were to place an object next to a wall, you, as the operator, would feel the wall if the object being held by the slave unit touched it.

Force reflection is force feedback but the power can also be amplified. A force-reflection ratio of 1:1 would be normal force-feedback (compensation for the units weight and inertia). A ratio of 1:10 would mean that, for example, the person operating the master unit would lift an object of 1 kilogram would amplify to 10 kilograms at the powered slave end.  The ratio can also go in the other direction and could apply to manipulators such as those used for surgical procedures.

The first prototype man amplifier wasn’t to be seen until General Electric built their Hardiman I, based on results from the Cornell research.”

Where would you publish a manuscript aimed at a technical counter-surveillance (eg. anti spy-gadget) method? Scientific journals on security are very focused on computer security, while most journals aimed at privacy are more into the sociological aspect of the problem. Is there any journal aimed at technical counter-surveillance or technical surveillance?

Micro Robots

SRI International have developed incredibly small and fast robots that are capable of following building instructions - video embedded below:

SRI is developing new technology to reliably control thousands of micro-robots for smart manufacturing of macro-scale products in compact, integrated systems.

The control panel from Vostok 1, the first human spaceflight. The Vostok 3KA spacecraft was launched on April 12, 1961 and took Yuri Gagarin, a cosmonaut from the Soviet Union into space. Due to concerns of adverse reactions from experiencing weightlessness, the manual controls on the spacecraft were locked prior to launch so the flight could be controlled by ground personnel.
