Fast and Robust Bio-inspired Teach and Repeat Navigation

The navigation of robots is a demanding task. Luckily, we can rely on biological systems, such as ants, which can navigate with limited vision and computing power. A recent study suggests a teach and repeat navigation system for repeated route following. It is based on wheel odometry, with vision providing a periodic correction signal. This technique can be applied to ...
