美国采购需求：摄像小车、陀螺仪机器人摄像小车、机器人塔、机器人小车、塔式起重机摄像机、塔式悬臂

I'm interested in the pricing for your latest gyroscope model. Could you please provide me with the cost details and any available options for bulk purchasing? Additionally, I'm curious if you have any demo units available for testing within the United States. It would be great to evaluate the product's performance firsthand before making a larger commitment. Thanks!
