Abstract | Wheel slip estimation is an important element in improving the performance of wheeled mobile robots. Conventional wheel slip estimation methods relied upon sensors which were far from the tyre-ground interface; hence, they required the use of approximated models and complex transformations. A modern method, which directly measures tyre-ground contact quantities utilising in-tyre sensors, helps develop accurate and direct wheel slip estimation techniques. The work presented in this paper represents a first stage towards developing such techniques for small, non-pressurised tyres that are widely used in mobile robots. An optimum sensing system for these tyres is presented. Experimental work is conducted to determine the possibility of bonding the selected system inside the tyre. Static footprint tests are undertaken to derive an optimal design for the sensing system. Image processing is utilised to obtain dimensions of the tyre-ground contact patches provided by these tests. Performance of the produced system design is evaluated with static tests using a custom-built, bench-top rig. Results of these tests demonstrated a sufficient degree of consistency in the measurements of the sensory system. In addition, the strain profiles extracted from the sensors' readings agree with key theoretical facts. |
