Spot model of `spoteus` with noetic does not visualize correctly about body color

[sktometometo]

I have created workspace based on https://github.com/k-okada/jsk_robot/tree/spot_arm/jsk_spot_robot#how-to-set-up-a-catkin-workspace-for-a-remote-pc and visualize spot model with IRTViewer, But its color is not correctly visualized.

(load "package://spoteus/spot-utils.l")
(spot)
(objects (list *spot*))

workspace configuration is

~/ros/ws_jsk_spot_remote/src $ wstool
workspace: /home/sktometometo/ros/ws_jsk_spot_remote/src

With these branch, arm color is also not visualized like below.

Code is https://gitlab.jsk.imi.i.u-tokyo.ac.jp/papers/2023/si/shinjo_device_localization_with_history/-/blob/master/euslisp/device_scene.l

and

(load "./device_scene.l")
(run-spatial-device)

During its execution, there are some outputs which seems to have relation with color

Since original xacro does not have color field in it, it seems that color information of STL or obj file seem not to be converted correctly to dae or euslisp.

For this error, I have to use spot-utils..l instead of spot.l Where spot model is updated.
