Training at VRLaboratory
Last month we reported that astronaut Wakata received joint training
with EVA crew members at the Neutral Buoyancy Laboratory (NBL), developing
and discussing EVA procedures. Joint training with EVA crew members
is very important for a robot arm operator. On June 7, Wakata received
joint training with astronaut Peter J. K. "Jeff" Wisoff, an
STS-92 EVA crew member, using a Virtual Reality Laboratory (VRLaboratory).
The VRLaboratory is a training facility that utilizes virtual reality
technology. An EVA crew member wears a Helmet Mounted Display (HMD)
to receive training in an environment generated by computer graphics
techniques. The trainee wears gloves and attachments on his or her hands
and legs as shown in the photograph to reflect the detailed movement
of hands and legs in the CG image.
The VRLaboratory can display robot arm movement in the CG image. Astronaut
Wakata operates the simulated robot arm and the EVA crew movements are
displayed in one CG image. Astronauts are thus being trained in a virtual
reality world. The CG image fidelity is very high. Details of the Space
Shuttle cargo bay and various elements on the International Space Station
are precisely depicted and various situations can be seen from most
directions. Many astronauts have commented that the operations in the
VRLaboratory are almost identical to those on orbit.
SAFER Development Test Objectives
Four EVAs are being planned on mission STS-92. If there is extra time
during the fourth EVA after planned tasks are finished, NASA plans to
conduct a Development Test Objective (DTO) for a Simplified
Aid for EVA Rescue (SAFER). The robot arm operator and the EVA crew
member must cooperate in this DTO, which requires team work and cooperation
among the crew members.
Astronaut Wakata evaluated and confirmed the test from the technical
point of view in cooperation with astronaut Wisoff who will conduct
the SAFER DTO on orbit, confirming the trajectory, position and attitude
of the robot arm and the procedures for the robot arm operator and EVA
member for cooperative operation on orbit .
Since no time-consuming special preparations are required for using
the VRLaboratory, busy astronauts can save time, which is the advantage
of this facility. Astronaut Wakata often uses this facility to repeat
the points he did not fully understood or he felt like reconfirming
during the training conducted in the Neutral Buoyancy Laboratory, and
to generate flight data for operating the robot arm.
