Just a quick question about Camera/Ultrasonic Distance Sensor in Developers kit. I have searched for the Camera/Ultrasonic Distance Sensor cover's and none are available even at authorized dealer's and on your site. I might suggest that the cover's and or case's be added to the kit due to open motherboards. Individual purchase of both item's include the case/cover but not the more expensive Developers kit. Purchased the Revolution Roli Chassis at Robotshop and want to mount properly and securely.
