The biggest risk right now is making sure the motors can provide enough torque to move and hold the umbrella. Since umbrella size and weight greatly affect the required torque, we are estimating these values early and researching appropriate stepper motors and gear ratios. If the torque requirements end up being too high, we can reduce the canopy size or use additional gearing or mechanical support to reduce the load on the motors.
We’ve started working on the arms and joints design, and perception & estimation components.
