Sensorimotor self-learning model based on operant conditioning for two-wheeled robot

Traditional control methods of two-wheeled robot are usually model-based and require the robot’s precise mathematic model which is hard to get. A sensorimotor self-learning model named SMM TWR is presented in this paper to handle these problems. The model consists of seven elements: the discrete learning time set, the sensory state set, the motion set, the sensorimotor mapping, the state orientation unit, the learning mechanism and the model’s entropy. The learning mechanism for SMM TWR is designed based on the theory of operant conditioning (OC), and it adjusts the sensorimotor mapping at every learning step. This helps the robot to choose motions. The leaning direction of the mechanism is decided by the state orientation unit. Simulation results show that with the sensorimotor model designed, the robot is endowed the abilities of self-learning and self-organizing, and it can learn the skills to keep itself balance through interacting with the environment.     

Design of car battery protection device based on torsion spring

In recent years, electric vehicles are developing rapidly in automotive industry. When involved in accidents, if the batteries of electric cars break, it is likely to cause a short circuit and start a fire. Aimed at this issue, a car battery protection device based on torsion spring has been designed. The car battery protection device can deform in a particular pattern in a collision accident. Impact energy of the accident is absorbed by the deformation, which can significantly reduce impact force on the batteries. Meanwhile, based on the principle of maximum energy absorption, some crucial parameters of the device can be determined. Furthermore, an impact simulation conducted on ANSYS software shows that maximum safety factors can be obtained when the material of car battery protection device is carbon steel. The analysis of “safe space” in the car battery protection device shows that the device can prevent battery damage effectively in general circumstances, which means the reliability of the device has been verified. Therefore, when applied to electric vehicles, the car battery protection device, which can prevent secondary accidents, significantly improves the vehicle security in accidents.

现场直播轨道交通立法听证会的启示

2013年8月15日下午,上海市十四届人大常委会就《上海轨道交通管理条例(修订草案)》(以下简为《条例草案》)举行立法听证会。本次听证会进行了广播现场直播,这是上海举办立法听证会以来的首次尝试。长达3小时的现场直播,充分体现了对民意的尊重、对法律的敬畏。城市快速轨道交通由于其运能大、速度快、安全正点、节能环保等优势,已成为上海市民出行的首选,目前日均客流量达622万乘次。因此,轨道交通管理不仅涉及到广大市民的切身利益,而且关系到如何提升城市管理水平。前不久,《条例草案》通过各种渠道征求到各方面意见共1200多条。为进一步发扬立法民主、提高立法的科学性,上海市人大常委会主任会议决定,就公众意见比较集中的问题举行立法听证会,直接听取各种意见。
