To permit portability between Schools, this arena used stick-on clips to hold the outer walls in place. This is not recommended. They were fine for a few months, but slid out of alignment and broke in use. The system shown here and used below is preferable.

Bellerive Primary Grade 4/5 students used the first arena shown here. The aim of the students of this historic School (established 1842) was to achieve three laps of the arena using their NXT MindStorms robots. .
