impacts mental health; all this in addition to just being an all around environmental pollutant and eyesore.

We're achieving this by designing a modular system. The robot provides the physical sensors and actuators, we implement an autonomy software module to govern its behavior corresponding with its use-case, and we attach a tool for a specific mission. For our short-term plan, we are developing a robot that can navigate safely along a commercial corridor sidewalk while pulling a power sweeper. While our first target is combating litter, this modular approach with a focus on outdoor navigation allows for this robot to be used in numerous other cases. Swap out the power sweeper for a lawn mower or seeder and you can do largescale lawncare. Add in a painting attachment and you can paint lines on a set of athletic fields and take care of all their landscaping needs. Put a snowplow on the front and a salt spreader on back and it can take care of sidewalk snow removal and ice treatment, among other possibilities.
