I saw this question in one of the locked sub-forums, so I thought I would address it here. Robot Mesh Studio includes an online CAD system (we call it Mimics) to build your own online VEX IQ robots, which you can then program using any one of three languages (Blockly, Python, or Flowol). I’ve attached a screenshot of a user-built robot. If you have any questions, let us know. (Robot Mesh Studio, including the “Mimic” CAD application is free to use online, and you can save as many different projects as you would like.)
You can see Mimic programming in action on our Hour of Code page here, although you cannot modify these robots. Click on this link: http://www.robotmesh.com/studio/ and then click on “Create a New Project” to try Mimic programming on your own – just select the targe (pick "Mimic) and the programming environment (Blockly, Python or Flowol) and give it a try.
