Experimental Results for Image-based<br />

Geometrical Reconstruction for Spacecraft<br />

Rendezvous Navigation with Unknown and<br />

Uncooperative Target Spacecraft<br />

• unknown and uncooperative target<br />

objects observed with a camera only<br />

vision system<br />

• the target's 3D structure is reconstructed<br />

from a sparse point cloud extracted from<br />

a rendezvous-SLAM algorithm<br />

• 3D model can be used in a feedback<br />

manner for enhancing visual navigation<br />

processing tasks<br />

• demonstrated by experiments with real<br />

image data from in-house laboratory<br />

spacecraft rendezvous simulator<br />

Launching Penetrator<br />

By Casting Manipulator System<br />

Hitoshi Arisumi<br />

• Proposal of a launching planner that<br />

compensates for the timing error of<br />

releasing a penetrator<br />

• Development of a system to launch the<br />

penetrator with keeping its orientation<br />

constant<br />

• Realization of the target motion with the<br />

hardware<br />

• Verification of the effectiveness of the<br />

proposed method by showing that the<br />

error of the landing position is less than<br />

3.6% of the launching distance through<br />

experiments<br />

A Grouser Spacing Equation for Determining<br />

Appropriate Geometry of Planetary Rover Wheels<br />

Krzysztof Skonieczny, Scott J. Moreland,<br />

and David S. Wettergreen<br />

Robotics Institute, Carnegie Mellon University, USA<br />

• Wheel geometric and operating<br />

parameters are related, to predict<br />

minimum number of grousers<br />

• Wheels without enough grousers<br />

periodically induce forward soil<br />

flow ahead of the wheel<br />

• Forward soil flow is indicative of<br />

rolling resistance that reduces<br />

traction<br />

• Soil flow is observed through a<br />

glass sidewall and analyzed using<br />

computer vision<br />

Accuracy Improvement of<br />

Delay Time Compensation Based on<br />

the Coefficient of Restitution for a Hybrid Simulator<br />

• A hybrid simulator is effective method to<br />

examine the space robotic on the ground<br />

• This simulator suffers from a problem of<br />

energy increase due to delay times<br />

• The aim of this paper is to improve<br />

accuracy of delay time compensation<br />

• A collision experiment is carried out to<br />

validate the accuracy of the proposed<br />

compensation<br />

• Developed an augmented reality<br />

framework that enables operator to design<br />

and implement assistive virtual fixtures for<br />

teleoperation with significant time delay<br />

• Validated technical approach for on-orbit<br />

satellite servicing tasks on ground<br />

simulation robotic platform<br />

• Approach reduces task completion time<br />

and eliminating manipulation error<br />

• Approach provides improved virtual<br />
