To this end, we theoretically investigate the motion of an active bent rod under the slender-body limit. Specifically, we vary the angle between the two rods, relative arm lengths and the activity along the surface of the particle, and evaluate particle trajectories under different geometric and surface activity conditions. We find that under specific geometric and surface patterning conditions, particles move along a circular trajectory, which is in qualitative agreement with previous experimental data. Using particle trajectories, we evaluate the relative contribution of the geometric asymmetry in driving such active particles which would enable us to fine tune the design of these active particles for specific use cases.
