Doll-E 3.0 / Field-Ready Prototype of Stairclimbing Cart
Quantum Robotic Systems (QRS)
Founded in 2015, Quantum Robotic Systems Inc. (QRS) is a Toronto-based company focused on developing stair-climbing robots, carts and wheelchairs that carry cargo and people up and down stairs in a safer, easier and faster way. QRS has successfully collaborated with George Brown College on five previous research projects. In industry and the home, using stairs while carrying heavy or bulky things is a chore at best and a dangerous hazard at worst. QRS has developed and patented novel stair-climbing technology to address this problem. This technology makes using the stairs safer and more efficient for a broad spectrum of users (e.g., movers, couriers, seniors, people with impaired mobility, etc.).
QRS is collaborating with the George Brown College (GBC) and the Centre for Construction and Engineering Technology (CCET) to refine and improve the design of its stair-climbing material handling cart (‘Doll-E’) to make it more suitable for field trials by end-users. The outcome will be a Doll-E 3.0 prototype with enhanced robustness, stability and safety. The George Brown team will include Principal Investigator (PI) John-Allan Ellingson and two Mechanical Engineering Student Researchers (SRs).
The objectives of the project are: 1) Improve the robustness and safety of the mechanical design; 2) Increase the stability of the wheel base; 3) Make edge-detection brake more reliable; 4) Improve handle design and control switches; 5) Simplify design for the variable height step frame; 5) Incorporate a “swappable” battery system with UL-rated charger.
