The z-axis is in the direction of the joint axis. The x-axis is parallel to the common normal: = (or away from z n–1) If there is no unique common normal (parallel z axes), then d (below) is a free parameter. The direction of x n is from z n–1 to z n, as shown in the video below.
Sankyo Seiki, Pentel and NEC presented the SCARA robot as a completely new concept for assembly robots in 1981. The robot was developed under the guidance of Hiroshi Makino, [4] a professor at the University of Yamanashi. [2] Its arm was rigid in the Z-axis and pliable in the XY-axes, which allowed it to adapt to holes in the XY-axes. [5] [6]
[3] [4] This convention positions the joint frame so that it consists of a screw displacement along the Z-axis [] = (), and it positions the link frame so it consists of a screw displacement along the X-axis,
[4] 6 Axis arm with 3 axis making up a spherical wrist. [5] Maximum reach 878mm from center axis to center of wrist [5] Software selectable payloads from 4 kg to 2.5 kg [5] Arm weight: 83 kg (approximate) [6] Repeatability ±0.1mm [7] 2.5 kg max velocity: 500mm/sec straight line moves [7] 4.0 kg max velocity: 470mm/sec straight line moves [7]
Truck Parking Club analyzed numerous film databases to compile a list of 10 classic movies paying homage to the trucking industry.
The yield on the 10-year Treasury jumped to 4.43% from 4.29% late Tuesday, which is a major move for the bond market. It’s up substantially from August, when it was below 4%.
An already hectic holiday travel day was made more chaotic with two separate plane collisions on the tarmac at Boston Logan International Airport just hours apart on Monday.
Forward vs. inverse kinematics. In computer animation and robotics, inverse kinematics is the mathematical process of calculating the variable joint parameters needed to place the end of a kinematic chain, such as a robot manipulator or animation character's skeleton, in a given position and orientation relative to the start of the chain.
