Aragog is a quadruped powered by a Raspberry Pi. The creep gait is implemented using Python, which allows the robot to move forwards, backwards, left and right while maintaining equilibrium. The robot is also capable of recognizing special markers on the floor using a pretrained LeNet model neural network made using Keras and Tensorflow.
