Don't underestimate the EV3 building instruction robot. It is fast and easy to build, well designed (compact, stable with low center of gravity) and has sensors placed in reasonable locations. Without changes, you can solve at least 5 robot game missions: opening doors, remote communications, the slider part of the search engine, changing conditions, apprenticeship, and the engagement part of engagement. That is plenty for a rookie team, particularly if they use the sensors. With very minor changes you can greatly improve it. Change the gears in the robot arm to make the arm move more accurately. Add a rear bumper so the robot can back up against a wall to square itself. Put a stick on the robot arm so it can pick up loops and the reverse engineering basket.
