The miniature robot Ghost Minitaur (Ghost of the Minotaur) from the startup Ghost Robotics looks like a moving stool, but when you look closely, you can guess a dog, a favorite of people with a mischievous character, in the habits of the invention. A four-legged apparatus weighing 6 kg and a height of 400 mm can only be moved using the remote control, however, it also has the necessary sensors for autonomous movement. The built-in battery is enough for Ghost Minitaur to jump, run, tumble, pull door handles, climb stairs or a vertical wire mesh for 20 minutes. The maximum speed of movement reaches 2 m / s or 7 km / h, which is a lot for the robot. The unique structure of the robot lies in the fact that the system of each limb is directly connected to the motor (there are two of them for the front and rear \The impressive maneuverability of the Ghost Minitaur is provided by a direct drive system and an on-board processor from the STM32F microcontroller series. The areas of application of the robot, according to the developers, are obvious – this is search and rescue operations in case of emergency (search for people after landslides, earthquakes, explosions, etc.), surveillance, military sphere. The current version of Ghost Minitaur cost the inventors almost $ 10,000, but the commercial model may eventually enter the market for $ 1,500.
