FAQs

What is Acrobot?
Acrobot is the series name of open-source, accessible serial kinematics robotic arms built by ACROME.
What is the Acrobot used for?
Acrobots are used for teaching robotic algorithms and for research purposes. Users can develop their own advanced controls and serial kinematic algorithms while accessing each joint individually.
Does the product have built-in kinematics solver?
Yes. The courseware has rich example codes including the kinmatics calculations with documentation.
Does it have a gripper?
Acrobot doesn't have a default gripper. Users may consult ACROME to learn the gripper options.
Does the product comes with a controller and software/courseware?
Product comes with the controller, software and a companion courseware with example source codes.
Is there any after-sales support or training for the product?
A complimentary online support session is available after the delivery of the products. Standard support is provided via the phone, e-mail or remote desktop connection.
