That precision translates to real-time navigation by a robotic gripper that controls the wheelchair's joystick.

这种精确度能够转化为通过控制轮椅操纵杆的机器夹持器进行实时导航。

At first, the robot arm had to use its grippers to grab a cube, which it successfully learned to perform.

首先，机器人手须用它的手爪抓取立方体，它成功地学会了抓取立方体。

It's known as a parallel jaw gripper.

它被称为平行钳口夹具。

Engineers from the Massachusetts Institute of Technology have built one that uses a gripper, a sensor that detects force and a camera.

来自麻省理工学院的工程师们已经制造了这样的机器，它使用了夹钳，可以检测力量的传器和摄像头。

Your hands are gripping the grippers and so when you move, it moves.

你的手抓住了抓手，所以当你移动时，它就会移动。

You can hold a gripper with more strength and for longer if you're swearing.

如果你说脏话，你可以用更大的力气和更长时间地握住夹子。

That would cause the control loop to take over again, this time backing the gripper up.

这将导致控制回路再次接管，这次支持夹具。

The gripper is a balloon filled with foam pellets and coffee grounds.

抓手充满泡沫颗粒和咖啡渣的气球。

That way the gripper maintained its size and functionality.

这样，夹持器就可以保持其尺寸和功能。

But very simple grippers are capable of doing very complex things.

但非常简单的抓手能够做非常复杂的事情。

Then, researchers created a two-layered hydrogel gripper, by using what's called a Stereothographic 3D printer.

然后，研究人员使用所谓的 Stereotographic 3D 打印机创建了双层水凝胶夹具。

) When an operator turns the light on, the motor turns, the gripper opens and the payload drops away.

）当操作员打开灯时，电机转动，夹具打开，有效载荷下降。

Now they are looking to increase its modules and even add grippers, to enabling it to pick up or manipulate objects.

现在，他们正在寻求增加其模块， 甚至添加夹具，使其能够拾取或操纵物体。

It usually has four cameras on the robot, a gripper and the manipulator that allows it to lift objects as much as 30 pounds.

这机器人通常装备有四摄像头, 而且它的钳子和机械手使它能抬起多达30磅的物体。

Because the fluid powering the gripper is also used to cool it down, it takes more pressure to power movement at higher temperatures.

因为为夹具提供动力的流体也用于冷却它，所以在更高的温度下需要更大的压力来驱动运动。

Imagine that our gripper is really heavy, and even when the control loop says to stop, momentum causes the gripper to overshoot the desired position.

想象下，我们的夹具真的很重，即使控制回路说要停止，动量也会导致夹具超过所需位置。

Researchers experimented with two different robots, each equipped with a camera at the end of a gripper for manipulating different objects on a tabletop.

研究人员对两种不同的机器人进行了实验，每机器人都在夹具末端配备了摄像头，用于操纵桌面上的不同物体。

Your actuators, your cables and motors are uncertain, so you can't fully control your own gripper.

您的执行器、电缆和电机都不确定的，因此您无法完全控制自己的夹具。

Now actually in industry, there's even a simpler robot gripper, and that's the suction cup.

现在实际上在工业中，甚至还有种更简单的机器人夹具，那就吸盘。

Well if you look at a robot's gripper trying to do something, there's a lot of uncertainty in the cables and the mechanisms that cause very small errors.

好吧， 如果你观察机器人的抓手试图做某事，就会发现电缆和机制存在很多不确定性， 这些不确定性会导致非常小的错误。
