Carefully read the statement and determine whether it is true (T) or false (F). A differential drive robot cannot move in the direction along the axis – this is a singularity. Differential drive vehicles are very sensitive to slight changes in velocity in each of the wheels. Small odometry errors in the relative velocities between the wheels can affect the robot trajectory. They are also very sensitive to small variations in the ground plane and may need extra wheels (castor wheels) for support.
