It's an eclectic collection of objects, things like a 9-volt battery, a highlighter pen, a plastic kazoo. Baxter is supposed to pick an object up, shake its arm to make sure it has a good grip on it and set it back down on the table.</p> <p>Watching Baxter trying to pick up these objects is a little like watching paint dry. It seems to take forever for the robot to reach the battery, and when it does, it misses it with its gripper and just knocks it over.</p> <p>Frankly, it looks pathetic. Tellex doesn't disagree, but says there's a reason it seems so inept. "A lot of the stuff that is really, really, really hard for a robot to do, is almost effortless for a person to do," she says.</p> <div id="res455522777" class="bucketwrap internallink insettwocolumn inset2col "> <div class="bucket img"> <a class="imagewrap" id="featuredStackSquareImage407736307" href="https://www.npr.org/sections/money/2015/05/19/407736307/robots-are-really-bad-at-folding-towels" data-metrics-ga4='{"category":"recirculation","action":"story_recirculation_click","clickType":"inset box","clickUrl":"https:\/\/www.npr.org\/sections\/money\/2015\/05\/19\/407736307\/robots-are-really-bad-at-folding-towels"}' ><picture><source srcset="https://media.npr.org/assets/img/2015/05/19/towelfold-still_sq-7cfe90fa7f839d6b8a578fc46c70203f3b294608.png?s=100&c=15&f=png" data-original="https://media.npr.org/assets/img/2015/05/19/towelfold-still_sq-7cfe90fa7f839d6b8a578fc46c70203f3b294608.png?s=100&c=100&f=png" data-template="https://media.npr.org/assets/img/2015/05/19/towelfold-still_sq-7cfe90fa7f839d6b8a578fc46c70203f3b294608.png?s={width}&c={quality}&f={format}" data-format="webp" class="img lazyOnLoad" type="image/webp" /><source srcset="https://media.npr.org/assets/img/2015/05/19/towelfold-still_sq-7cfe90fa7f839d6b8a578fc46c70203f3b294608.png?s=100&c=15&f=png" data-original="https://media.npr.org/assets/img/2015/05/19/towelfold-still_sq-7cfe90fa7f839d6b8a578fc46c70203f3b294608.png?s=100&c=100&f=png" data-template="https://media.npr.org/assets/img/2015/05/19/towelfold-still_sq-7cfe90fa7f839d6b8a578fc46c70203f3b294608.png?s={width}&c={quality}&f={format}" data-format="png" class="img lazyOnLoad" type="image/png" /><img src="https://media.npr.org/assets/img/2015/05/19/towelfold-still_sq-7cfe90fa7f839d6b8a578fc46c70203f3b294608.png?s=100&c=15&f=png" data-original="https://media.npr.org/assets/img/2015/05/19/towelfold-still_sq-7cfe90fa7f839d6b8a578fc46c70203f3b294608.png?s=100&c=100&f=png" data-template="https://media.npr.org/assets/img/2015/05/19/towelfold-still_sq-7cfe90fa7f839d6b8a578fc46c70203f3b294608.png?s={width}&c={quality}&f={format}" data-format="png" class="img lazyOnLoad" alt="Robots Are Really Bad At Folding Towels" loading="lazy" /></picture></a> <div class="bucketblock"> <h3 class="slug"><a href="https://www.npr.org/sections/money/">Planet Money </a></h3> <h3><a href="https://www.npr.org/sections/money/2015/05/19/407736307/robots-are-really-bad-at-folding-towels" data-metrics-ga4='{"category":"recirculation","action":"story_recirculation_click","clickType":"inset box","clickUrl":"https:\/\/www.npr.org\/sections\/money\/2015\/05\/19\/407736307\/robots-are-really-bad-at-folding-towels"}' >Robots Are Really Bad At Folding Towels</a></h3> </div>  </div>  </div>  <p>But, Tellex says, look at it from the robot's point of view.
