Hello my name is Michael.
I work as a company engineer and technician for sewer inspection systems. I develop systems that facilitate and expand our work. Small help and new controls via ATMEGA and ESP as well as Nextion formed the beginning. Also PIC programming is part of it. As a side project, I once dealt with the Raspberry PI (3b +) and so by chance came across the Turtle Rover. I am excited about the design and construction. Thanks to the great CAD drawings, I was able to think of some addons that help us with our work. Unfortunately, it is more difficult than expected with 5 programming languages that you do not 100% mastered to consider an addon. But I am currently working on it. The first goal is achieved, a second camera module with live stream (UV4L low latency) in 720p with recording function, microphone, full screen and simultaneous viewing of the images. A 2 servo gimbal (both 180 degrees) is also implemented as well as 1 relay port to control the lighting (all controllable via webserver). As a camera body, I have rebuilt a defective GOPRO session and replaced the electronics with a camera module USB. The lighting consists of 2x litratorch lamps. The switch of the lamps will be replaced by the relay port and you can switch through 3 brightness levels including SOS. The internal batteries have been retained and deliver about 45min at full illumination. As a backup, they are connected to the Turtle power supply. The heart of this module is its own RAspberry pi.
Next, a Kinect is implemented via ROS NODE and an attempt is made to visualize the IMU via Websocket. An extension of 14 PWM channels is almost finished. Kinematics is not so important to control any of these channels with any robot arm, as the inserts are too individual. In addition, my options over ros are simply too expensive.
Mind you, this is a stand-alone addon but tailored to the Turtle Rover.
