These N20 Gearmotors are perfect for fairyweight and antweight robots. These are the motors we use in all of our antweight robots including 2 time CIRC champion "Death by 1001 Cuts" They are somewhat fragile compared to other offerings but they are significantly cheaper which allows for more spares.
You may be tempted to go lower gear ratio however experience has shown us that slower robots are much more successful than faster ones because they are easier to control and have more pushing power.
