Opening the Claw

To use the claw on your VEX IQ Clawbot, first you need to configure the Clawbot in VEXcode. The easiest way to do this is to open a Clawbot template.

Configure the Clawbot

Select a Build

Go to the Devices tab, then select Select a build.

Select the Clawbot Build

Scroll down and select the Clawbot build.

Choose the Clawbot Variant

The build used for this tutorial is the Drivetrain, Claw Motor version of the Clawbot.

Confirm the Configuration

Select Done to add this build to your project.

Code the Claw

Open the Motion Category

Select the Motion category in the toolbox to find the Motion blocks, including the spin blocks for the ClawMotor.

Attach the Spin Block

Attach the spin motor for block to the when started block.

Open the Claw

Change the direction parameter to open instead of close, and change the distance parameter to 60. This will open the robot’s claw 60 degrees from its current position.

When started, opens the claw 60 degrees from its current position.

You can also change the units parameter to turns instead of degrees. One turn is equal to 360 degrees.

Using Motor Timeouts

One tip is to use the set motor timeout block before using the spin motor for block.

The set motor timeout block.

设定 [ClawMotor v] 超时为 (1) 秒

If you accidentally set the spin motor for block to too great of a distance, the set motor timeout block will force it to end, and the project to move on, even if the motor hasn’t reached the position it wanted to.

When started, sets a 1 second timeout before opening the claw, so the project moves on even if the claw doesn’t reach its target position.
