ViSP standing for Visual Servoing Platform is a modular cross platform library that allows prototyping and developing applications using visual tracking and visual servoing technics at the heart of the researches done by Inria Lagadic team. ViSP is able to compute control laws that can be applied to robotic systems. It provides a set of visual features that can be tracked using real time image processing or computer vision algorithms. ViSP provides also simulation capabilities. ViSP can be useful in robotics, computer vision, augmented reality and computer animation.

ESP32-Cam-tank: fpv vehicle powered by esp32 cam

Kun Li created this amazing Tank Teleoperated Robot. 

ESP32-Cam-tank

a fpv vehicle powered by esp32 cam.
This project use a esp32-cam chip to make a common toy into a fpv rc toy.
It can record videos. It also has telemetry to monitoring the battery voltage and wifi signal strength.
Welcome to modify/upgrade and share.

material list:
ESP32-cam x 1
MX612/MX612E x 2
dc-dc converter 1.5~4.2v to 5.2v x 1

Nordic nRF52811, nRF52820, nRF52833, nRF52840  Are also supposed to be able to support AOA on BE 5.1 but in looking tough their forums, No one seems to have been able to make it work. There is no dev boards or demo kits even though there are many arduino ecosystem modules using these.

TI also has the CC2640R2F

Open Dynamic Robot Initiative

An Open Torque-Controlled Modular Robot Architecture for Legged Locomotion Research

https://open-dynamic-robot-initiative.github.io/

In this video, we show a new set of jumps on Solo8. We are evaluating modifications to the leg design to make it more robust against high impact forces. We executed 38 very high jumps (with maximum height of 106 cm) on the robot and did not observe any damage of the 3d printed structural parts.
