A Force Bounding Approach in Joint Space for Interacting With Dynamic Multi-Degrees of Freedom Virtual Objects
IEEE Transactions on Haptics
|September 4, 2018
Summary
This study introduces a dynamic force bounding approach (dynamic FBA) for stable human-robot interaction with moving virtual objects. The method ensures stable and transparent haptic feedback, even with complex multi-DOF systems.
Area of Science:
- Robotics
- Human-Computer Interaction
- Haptics
Background:
- Previous static approaches struggle with dynamic virtual objects.
- Operator-only motion consideration limits interaction force display.
- Need for stable interaction with multi-DOF virtual environments.
Purpose of the Study:
- Propose a novel relative motion-based dynamic force bounding approach (dynamic FBA).
- Enable stable haptic interaction with dynamic multi-degrees of freedom (DOF) virtual objects.
- Improve force feedback for moving virtual environments.
Main Methods:
- Derived a new multi-DOF passivity condition in joint space.
- Incorporated relative motion between operator and virtual object.
- Developed a dynamic FBA controller.
Main Results:
- The dynamic FBA ensures stability during interaction.
- Demonstrated direction transparency in haptic feedback.
- Validated effectiveness across various dynamic scenarios.
Conclusions:
- The proposed dynamic FBA enables stable and transparent haptic interaction.
- Effective for passive or slightly active dynamic multi-DOF systems.
- Overcomes limitations of static force bounding methods.

In mechanical engineering, one-degree-of-freedom systems form the basis of a wide range of electrical and mechanical components. Using these models, engineers can predict the behavior of various parts in a larger system, which gives them insight into how different forces interact with each other.
A one-degree-of-freedom system is defined by an independent variable that determines its state and behavior. One example of a one-degree-of-freedom system is a simple harmonic oscillator, such as a...

The degree of freedom for a particular statistical calculation is the number of values that are free to vary. Thus, the minimum number of independent numbers can specify a particular statistic. The degrees of freedom differ greatly depending on known and uncalculated statistical components.
For example, suppose there are three unknown numbers whose mean is 10; although we can freely assign values to the first and second numbers, the value of the last number can not be arbitrarily assigned.

The degree of unsaturation (U), or index of hydrogen deficiency (IHD), is defined as the difference in the number of pairs of hydrogen atoms between the compound and the acyclic alkane with the same number of carbon atoms. Each double bond or ring costs two hydrogen atoms compared to a saturated analog and results in one degree of unsaturation.
The degree of unsaturation for hydrocarbons is U = (2C + 2 − H) / 2, where C is the number of carbon atoms and H is the number of hydrogen atoms.
The degree of unsaturation for hydrocarbons is U = (2C + 2 − H) / 2, where C is the number of carbon atoms and H is the number of hydrogen atoms.

01:20Virtual Work
1.4K
The principle of virtual work states that if a body is in static and dynamic equilibrium, then the sum of all the virtual work done by all external forces and couple moments for any given virtual displacement must be zero.
In static equilibrium, a body can experience an imaginary or virtual movement, such as displacement or rotation. The virtual work done by a force is equal to the dot product of force and virtual displacement in the direction of the force. When it comes to virtually rotating a...

71.5K
Atoms and molecules interact through bonds (or forces): intramolecular and intermolecular. The forces are electrostatic as they arise from interactions (attractive or repulsive) between charged species (permanent, partial, or temporary charges) and exist with varying strengths between ions, polar, nonpolar, and neutral molecules. The different types of intermolecular forces are ion–dipole, dipole–dipole, hydrogen bonds, and dispersion; among these, dipole–dipole, hydrogen...
