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，机器人手臂必须用它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.

手抓住了抓手，所以当移动时，它就移动。

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.

来自麻省理工学院工程师已经制造了一个这样机器，它使用了一个夹钳，一个可以检测力量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接管，这回到抓取器位置。

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

它包括Sherpa系列周日拖鞋、便于打包防滑拖鞋，甚至还有防水EVA材质周五滑板鞋。

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.

但非常简单夹持器能够完成非常复杂工作。

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。

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

现在他正计划增加其模块， 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老虎钳类似效果。

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.

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

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

执行器、电缆和电机都有不确定性，所以无法完全控制自己夹持器。

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，有一种更简单机器人抓取器，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.

看看机器人抓取器在尝试做某事时，电缆和机制中不确定因素导致很小误差。

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.

可以让机器人用夹爪或爪子来做事情，但这很难，所以我想建造一只像人类一样手，这将使机器人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.

如果怀疑简单手也能有效工作，看看这段视频，在视频中可以看到两个非常简单夹持器，顺便说一句，这些夹持器是由人类像操纵木偶一样控制。
