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，机器手必须用它的手爪抓取一个立方体，它成功地学了抓取立方体。

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，它就移动。

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

现在实际上在工业领域，有一种更简单的机器抓取器，那就是吸。

What it is, is a compliant mechanism that is a gripper.

它是一种柔顺机构，用作夹爪。

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一个这样的机器，它使用了一个夹钳，一个可以检测力量的传感器和一个摄像头。

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

那样导致控制循环再次接管，这次到抓取器的位置。

They're Sherpa line Sunday slippers to packing friendly gripper slippers and even waterproof EVA Friday slides.

它们包括Sherpa系列的周日拖鞋、便于打包的防滑拖鞋，甚至还有防水EVA材质的周五滑板鞋。

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

你的执行器、电缆和电机都有不确定性，所以你无法完全控制自己的夹持器。

It's known as a parallel jaw gripper.

它被称为平行爪夹持器。

) 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。

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

但非常简单的夹持器能够完成非常复杂的工作。

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

这个机器通常装备有四个摄像头, 而且它的钳子和机械手使它能抬起多达30磅的物体。

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

现在他们正计划增加其模块， 并添加抓手，使其能够拾取或操作物体。

This gripper is just a single piece of plastic, but achieves a similar result to the much more complicated vice grips.

这个夹具只是一块塑料，但却达到了更为复杂的老虎钳类似的效果。

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.

想象我们的抓手非常重，即使控制路发出停止指令，由于惯性，抓手还是超过预期位置。

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.

看看机器的抓取器在尝试做某事时，电缆和机制中的不确定因素导致很小的误差。

You can get a robot to do things with a gripper or a claw, but it's hard, so we thought build a human-like hand and that will make life as easy as possible for the robot.

你可以让机器用夹爪或爪子来做事情，但这很难，所以我们想建造一只像类一样的手，这将使机器运动起来尽可能地容易。

And if you're doubting that simple hands can be effective, look at this video where you can see that two very simple grippers, these are being operated, by the way, by humans who are controlling the grippers like a puppet.

如果你怀疑简单的手也能有效工作，看看这段视频，在视频中你可以看到两个非常简单的夹持器，顺便说一句，这些夹持器是由类像操纵木偶一样控制的。
