My team has the rollers from the field elements kit, but we can’t really set up an actual field anywhere. When we try testing our roller mech, it is really to hold it in place using hands. Is there any way to test rollers without a field wall?
If you have a spare cardboard box, you could probably cut it and mount it to the rollers.
You can maybe use a couple c-channels and build a fake wall which you can mount the roller to, and tape it to the floor. Just make sure to not push too hard on it.
You can take some 3M or tape and tape it to the wall.
