Educational robotics is considered a powerful tool, not only to learn how to program artificial agents but also to support students in developing high-order thinking skills. this paper reports a narrative review of empirical studies performed in the last twenty years, that investigate the effectiveness of using playful robotics as tools for enhancing cognitive abilities such as metacognition, awareness, and problem-solving, also improving planning and executive functions. the evidence from the scanned literature supports the effective impact of using robotics as an educational metacognitive gaming environment that allows students to monitor themselves and controltheir learning actions autonomously. Moreover, the data provide scientific support to the hypothesis that educational robotics can improve the ability to plan and control complex tasks, favoring the development of executive functions and math or STEM achievement.
One of the most important fields in robotics is the optimization of controllers. Currently, robots are often treated as a black box in this optimization process, which is the reason why derivative-free optimization me...

Bat wings contain dozens of joints that enable the animal to perform aggressive maneuvers by means of changing the wing shape during flight. there is evidence that the inertial forces produced by their wings during flapping have a key role in the attitude movements of the animal, i.e. aerial rotations. In fact, bats efficiently generate net body forces to manoeuvre by taking advantage of their large wing-to-body mass ratio. In this paper, the following question is formulated: Could a Micro Aerial Vehicle (MAV) inspired by the biomechanics of bats take advantage of the morphing-wings aimed at increasing net body forces? Using BaTboT, a novel bat-like MAV with highly articulated wings actuated by shape memory alloy actuators, our goal is to quantify the effects of different wing modulation patterns on the generation of net body forces. Experiments are carried out to confirm the important physical role that changing the wing shape enables: the contraction time of the wings (upstroke) should be faster than the extension time (downstroke), taking about 37.5% of the wingbeat period. this modulation pattern has enabled a lift force increment of 22% (from L = 0.92N to L = 1.12N), abrupt drag reduction (from D = 0.22N to D = 0.11N) and also an increase of net body forces (Fnet) about 28% compared to those wing modulation patterns defined with equal periods for contraction/extension. these findings can be useful for accurate dynamics modelling and efficient design of flight controllers applied to morphing-wing micro aerial vehicles.
