Robot Kinematics Gripper Mechanism

The order of transformation for frame to frame starts with translation along the axis by distance , followed by translation along the axis by distance , then rotation by an angle about the axis, and finally rotation by an angle about the axis.

Link parameters refer to the physical characteristics of the robot’s links such as length mass and moments of inertia These are constants for a given link and are typically used in robot kinematics and dynamics calculations

In homogeneous transformation matrices used in robotics the scale factor is typically one This is because the transformation matrices are used to describe the position and orientation of objects without scaling them Statement (I) is incorrect while Statement (II) is correct

The minimum number of degrees of freedom required for assembling a round peg into a round hole is 3 This includes two translational degrees of freedom (moving along X and Y axes) and one rotational degree of freedom (rotation around the center)

Step 1: Understand the resolution calculation.
The control resolution is the smallest increment of movement that can be controlled by the robot. This is determined by the number of bits in the control memory and the range of motion.
The total number of divisions of the range is: Step 2: Calculate the resolution. The resolution is the total range divided by the number of divisions: Step 3: Conclusion The control resolution for the robot's axis of motion is 0.244 mm. Final Answer:

Step 1: Understand the SCARA robot's structure.
A SCARA (Selective Compliance Assembly Robot Arm) robot is known for its rigid movement in the vertical direction and flexibility in the horizontal plane. It typically has four degrees of freedom:
(A)Two rotational degrees of freedom for the arm,
(B)One vertical translational degree of freedom,
(C)One rotational degree of freedom for the wrist.
Step 2: Conclusion Thus, a SCARA robot has four degrees of freedom. Final Answer:

Step 1: Understand the types of robot joints.
In robotics, joints are classified based on their type of motion:
- A prismatic joint allows for translatory or linear motion, i.e., movement along a straight path.
- A revolute joint allows for rotational motion.
- Spherical and cylindrical joints provide a combination of rotational and translational motion, but the prismatic joint is the one specifically for translatory movement.
Step 2: Conclusion The translatory joint in a robot is known as a prismatic joint. Final Answer:

Step 1: Understand robot arm configurations.
Robotic arms are often represented using notations to describe their link and joint configurations:
- LLL denotes a robot with three links and three revolute joints (revolute joints allow rotational movement).
- The other options describe various combinations of joints and links, but LLL is the standard notation for a robot with joined arm configurations, specifically with three links and three revolute joints.
Step 2: Conclusion
The correct notation for a robot with a joined arm configuration is LLL. Final Answer:
