1) Why Anti-Poaching Drones Haven’t Worked Well.
INFO: This post on DIY Drones by Chris Anderson highlights a discussion from ArduPilot Discourse on the topic of using drones for anti poaching efforts. The discussions are interesting both from the engineering and environmental perspective. As user Graham_Dyer says in one of his post: “From my experience I believe, that even with the best intentions and best technology, drones will never have more than a negligible effect on poaching. To put it in context, the Canine teams in the KNP’s best haul was 18 poachers apprehended in one week. Our drone team saw less than 8 poachers in TWO years of night flying, with not one apprehension. So if the drone is not CATCHING an average of 2-5 poachers a WEEK then it’s of no use. And note that poachers get around deterrents easily”.
2) 3 New Chips to Help Robots Find Their Way Around.
INFO: This article from IEEE highlights advances in systems-on-chip (SoC) that can perform robot navigation and path planning and even visual SLAM (Simultaneous Localization and Mapping).

INFO: In issue #28 we’ve presented MIT Mini Cheetah. The Super Mini Cheetah is another project from MIT Biomimetics Lab. Compared to the larger version the Super Mini is a low cost build that has simpler kinematics and in our opinion resembles a Cheetah a lot more than it’s bigger brother (it might have to do with the robot’s head).
4) Supervised Racing.
INFO: This blog post from January describes Donkeycar project (presented in Weekly Robotics #2) AI. We think that the post gives a nice big picture of how Donkeycar works. The team behind Markku recently open sourced a set of 3D designs that can be used for attaching the required hardware to the R/C car.

7) Publication of the week - Autonomous Drifting using Simulation-Aided Reinforcement Learning (2016).
INFO: This paper by Mark Cutler and Jonathan P. How introduces a framework that combines simple and complex continuous state-action simulators with a real-world robot to efficiently find good control policies, while minimizing the number of samples needed from the physical robot. While many Reinforcement Learning Researchers use expert demonstration to initialize the models, the authors of this paper chose an approach in which they generate initial policies from simple models. On the car Researchers track velocities in x and y direction (the information is provided by a motion capture system), turn rate and wheel speed. By applying the algorithm shown in this paper combined with prior simulated information the R/C car was able to drift as it can be seen in this YouTube video. You can download additional material to the paper here.
