Development of Floating Off-The-Ground (OTG) Mobility Technology for New Personal Mobility
Funded by: MOTIE
Period: 2020 – 2022
Keywords: OTG mobility, Dynamics, Stability control
Overview
This project developed a novel Off-The-Ground (OTG) personal mobility platform — a vehicle concept that operates partially or fully elevated from the ground surface. The work covered dynamics modeling, control system design, and iterative stability experiments for safe operation.
Key Contributions
- Developed dynamics model for the OTG platform and designed the corresponding control architecture
- Established test scenarios and log analysis pipeline for safe operation validation
- Conducted iterative stabilization and response characterization experiments
