A balancing arm (the forearm) has on one side of an axis a small counterweight and on the other side a lamp cap. These parts are lifted by a second bigger balancing arm (the upper arm) that has on the other side of a second axis a heavier counterweight. The lamp designed by Edouard-Wilfrid Buquet in 1927 works in this way.
Robot arms are described by their degrees of freedom. This is a practical metric, in contrast to the abstract definition of degrees of freedom which measures the aggregate positioning capability of a system. [3] In 2007, Dean Kamen, inventor of the Segway, unveiled a prototype robotic arm [4] with 14 degrees of freedom for DARPA.
A manipulator can move an object with up to 6 degrees of freedom (DoF), determined by 3 translation 3T and 3 rotation 3R coordinates for full 3T3R mobility. However, when a manipulation task requires less than 6 DoF, the use of lower mobility manipulators, with fewer than 6 DoF, may bring advantages in terms of simpler architecture, easier control, faster motion and lower cost.

To replace the ALCM, the USAF planned to award a contract for the development of the new Long-Range Stand-Off weapon in 2015. [6] Unlike the AGM-86, the LRSO will be carried on multiple aircraft. The LRSO program is to develop a weapon that can penetrate and survive integrated air defense systems and prosecute strategic targets.
Le Corbusier's Modulor scale of proportions. Humans interact with their environments based on their physical dimensions, capabilities and limits. The field of anthropometrics (human measurement) has unanswered questions, but it's still true that human physical characteristics are fairly predictable and objectively measurable.
The top half of the instrument is blue to represent the sky, while the bottom half is brown to represent the ground. The bank index at the top shows the aircraft angle of bank. Reference lines in the middle indicate the degree of pitch, up or down, relative to the horizon. [2] [1] Most Russian-built aircraft have a somewhat different design.
