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机夹持实时导航。

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

首先，机人手臂必须用它手爪抓取一个立方体，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.

来自麻省理工学院工程师们已经制造了一个这样机，它使用了一个夹钳，一个可以检测力量传感和一个摄像头。

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

你手抓住了抓手，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。

That way the gripper maintained its size and functionality.

这样，夹持就可以保持其尺寸和功能。

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

后，研究人员使用所谓 Stereotographic 3D 打印机创建了一个双层水凝胶夹具。

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

但非常简单抓手能够做非常复杂事情。

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

抓手是一个充满泡沫颗粒和咖啡渣气球。

) 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.

这个机人通常装备有四个摄像头, 而且它钳子和机械手使它能抬起多达30磅物体。

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流体也用于冷却它，所以在更高温度下需要更大压力来驱动运动。

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

您执、电缆和电机都是不确定，因此您无法完全控制自己夹具。

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.

想象一下，我们夹具真很重，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机人了实验，每个机人都在夹具末端配备了一个摄像头，用于操纵桌面上不同物体。

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，甚至还有一种更简单机人夹具，那就是吸盘。

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， 如果你观察机人抓手试图做某事，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错误。
