How does the Clawbot get power?
The clawbot kit itself does not include a battery. The larger VEX Classroom and Competition kits and Robot Starter Kits (that are built around the Clawbot) include the VEX 3000 mAh battery:http://www.vexrobotics.com/276-1491.html
This is the battery we recommend Clawbot users purchase.
Thanks for the information. We have been able to get the claw to grab the sacks, but it is not strong enough to pick it up. Do you know how to increase the strength of the claw?
