6WD all terrain robot

The robot has a manipulator with 4 degrees of freedom. All rotary axes are controlled from the 2.4 GHz transmitter. In the following video we can see how the robot grabs and lifts a screwdriver and a wheel from the floor.

Currently I'm developing a dedicated application for 6WD security robot. This app providing the following functionality:

• preview and record the image in real time
• snapshots
• detecting moving objects
• marking detection zones
• automatic sending of alarm notifications

I'm using Python, OpenCV and TensorFlow when creating and testing this software.

The view from the wifi camera is displayed on the smartphone and from the fpv camera on the laptop.

Cameras used in the project:

1. RunCam OWL Plus - https://goo.gl/4fSgZ5
2. XiaoMi YI Wifi camera

Due to winter conditions in my area, I decided to do field tests in a nearby forest. How did it go?  See for yourself ;)

The first tests of grasping and moving an object based on a camera view. The inspection robot is remotely controlled from a safe distance by the operator.

Tests of a 6-wheel robot in rough terrain. Overcoming obstacles at different speeds.

The above video shows the first tests of 6WD robot in my room. This robot is able to carry a load of several kilos very easily, on the video it transports 8 bottles of water equivalent to 12 kg. The robot can also easily overcome various obstacles encountered on its way. The speed of the robot is regulated in its full range via a 2.4 GHz transmitter.

Just a quick instruction how to connect the RunCam Split camera and get preview from it on the mobile device like a tablet or smartphone.

In this project log I'll show you how to connect and control a 2 axis gimbal from Ehang Ghost Quadcopter using Taranis Q X7 2.4GHz transmitter and FrSky V8FR-II receiver.
