SSRR - Stability discriminant of a Tracked Vehicle to traverse stairs
2016 IEEE International Symposium on Safety Security and Rescue Robotics (SSRR), 2016Co-Authors: KANAME NAGATANI, Daisuke EndoAbstract:In some surveillance missions in the aftermath of disasters, the use of a teleoperated Tracked Vehicle contributes to the safety of rescue crews. However, because of its insufficient traversal capability, the Vehicle can become trapped upon encountering rough terrain. This may lead to mission failure and, in the worst case, loss of the Vehicle. To improve the success rate of such missions, it is very important to assess the traversability of a Tracked Vehicle on rough terrains based on objective indicators. From this viewpoint, we first derived physical conditions that must be satisfied in the case of traversal on stairs, based on a simple mechanical model of a Tracked Vehicle. We then proposed a traversability assessment method for Tracked Vehicles on stairs. In other words, we established a method to evaluate whether or not a Tracked Vehicle can traverse the target stairs. To validate the method, we conducted experiments with an actual Tracked Vehicle on our mock-p stairs, and we observed some divergences between our calculation and the experimental result. Therefore, we analyzed possible factors causing these divergences, estimated the influence of the factors. In this paper, we report the abovedescribed assessment method, the experiments, and the analyses.

On steering regenerative brake torque control of dual-motor drive for electric Tracked Vehicle
Proceedings of the 29th Chinese Control Conference, 2010Co-Authors: Li ZhaiAbstract:Studies the steering regenerative brake torque control of dual-motor drive for electric Tracked Vehicle. The force condition of the dual-motor is analyzed by making up the steering dynamic model of Tracked Vehicle. Steering regenerative brake torque control strategy of induction motor based on rotor flux oriented and complex speed-torque control method of steering regenerative braking of dual-motor are proposed, and energy feedback produced by steering regenerative braking is discussed. Experimental results of dual-motor drive characteristic show that stepless smooth steering is achieved.
