20251ROB1: Floor Cleaning Robot

Last updated on 
20251ROB1: Floor Cleaning Robot
Karcher Push Sweeper-(Source)

Brief Introduction & Functionality

The proposed floor cleaning robot is a modified version of the Karcher S 4 Twin Push Sweeper, originally designed for manual collection of dust, leaves, and other dry debris. This project aims to transform the manually-operated sweeper into a semi-autonomous or fully autonomous robotic floor cleaner tailored for use in a woodworking shop environment. The robot will be enhanced with sensors, control systems, and drive mechanisms to navigate and operate autonomously within workshop conditions, efficiently collecting fine wood dust, chips, and small debris scattered across the floor.

Sweeping and Debris Collection (Already present):

  • Retains the original dual side brushes and central roller of the Karcher S 4 Twin for effective mechanical sweeping.
  • Designed to collect fine wood dust, small chips, and other workshop debris into the onboard collection container.

Drive System Integration:

  • Motors will be retrofitted to the wheel assembly to provide powered mobility.
  • Motor drivers and a control board (such as Arduino or Raspberry Pi) will manage motion and enable variable speed and direction control.

Power and Control:

  • Operates on a rechargeable battery system for mobility without the need for tethered power.
  • An onboard microcontroller or single-board computer will handle motion control, sensor input (if added), and execution of the cleaning routine.

Design Scope

  1. Modification of existing Karcher Push Sweeper (Source)
