Opening the Claw#

To use the claw on your VEX V5 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.

Choose the Drivetrain Variant #

The build used for this tutorial is the Drivetrain, Inertial version of the Clawbot, which includes both a Claw and an Arm motor.

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 spin blocks.

Attach the Spin Block #

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

girar [ArmMotor v] [arriba v] por (90) [grados v] ▶

Select the ClawMotor #

By default, the block’s motor parameter is set to ArmMotor. Select the dropdown and choose ClawMotor instead, so the block controls the claw.

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.#

girar [ClawMotor v] [abierto v] por (60) [grados v] ▶

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.#

establecer tiempo límite de [ClawMotor v] a (1) segundos

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.#
