There's a lot of information on the Development Environment here, and on QRC's main website (Click QRC Home Page Above). The SDK is free of charge, and includes a fully development virtual machine which has all the tools, APIs, and drivers needed to begin creating your own WBT Apps. The SDK will require a NDA (QRC's standard NDA is attached) be signed between you and QRC, after which links will be provided for easy download.. Please feel free to contact us at firstname.lastname@example.org, or post here and we'll get you what you need to get up and running quickly.
