A year later, it had come a long way, gaining much better motor skills and the ability to maintain balance. During a CES 2020 demo(演示), UBTech showed how far Walker had come.The robot walked over to a table, picked up a bottle opener and used it to remove the cap from a bottle of soda. It picked up the bottle and a glass and poured the liquid in, without spilling.During the demo, Walker also performed a number of serious Yoga( 瑜伽) poses, including standing on one foot and leaning back.

UBTech said that the ability to pour drinks required visual servo( 伺服系统) technology using its cameras to judge the position of objects. The same methods allowed Walker to uncap a marker and draw a picture of a flower on a piece of paper at another point in the demo.

All of the betterment was made via software as UBTech hasn't made any physical adjustments t0o the robot since we saw it last year. On the inside, the robot uses a combination of a few different operating systems on these internal PCs, including Ubuntu, ROS and Android. Its battery promises up to 2 hours battery life after a 2-hour charge time,

UBTech continues development on this pioneering robot, but doesn't have public launch date. The company is targeting Walker toward the home, with an emphasis on helping seniors or. just doing house cleaning. To make it stable enough to adapt to all these different conditions is a huge challenge. However, if development of Walker continues, this robot could eventually be a game-changer.

【4】C

【解析】

本文是说明文。文章介绍了UBTech公司开发的Walker机器人，它具备执行许多任务的能力。Walker的继续发展可能会让我们的生活更加便利。

【1】

细节理解题。根据第一段中的“I was blown away by its ability to perform many tasks.”可知，我对它执行许多任务的能力感到震惊。即作者在初次见到这个机器人时感到很惊讶。故选A。

【2】

段落大意题。根据第二段可知，一年后它获得了更好的运动技能和保持平衡的能力。它走到桌子旁，拿起开瓶器，用它从一瓶苏打水上取下了瓶盖。它拿起瓶子和杯子，倒入液体时没有溢出。在演示过程中，Walker还进行了许多瑜伽姿势，包括单脚站立和向后倾斜。即第2段的主要内容是随着时间的推移，机器人功能的改进。故选B。

【3】

细节理解题。根据第三段中的“UBTech said that the ability to pour drinks required visual servo( 伺服系统) technology using its cameras to judge the position of objects. The same methods allowed Walker to… draw a picture of a flower on a piece of paper at another point in the demo.”可知，UBTech表示，倒饮料的能力需要使用视觉伺服技术，即使用相机来判断物体的位置。相同的方法使Walker在纸上绘制花朵的图片。由此可知，位置判断系统使机器人能够画画。故选D。

【4】

推理判断题。根据最后一段可知，UBTech继续开发此开创性机器人，但尚未公开发布日期。该公司将Walker瞄准家庭，重点是帮助老年人或打扫房子。要使其足够稳定以适应所有这些不同条件是一个巨大的挑战。但是，如果继续推动Walker的发展，那么该机器人最终将成为改变游戏规则的人。因此，从最后一段我们可以推断出机器人可能会极大地影响我们的生活。故选C。
