Power Supply

The car’s power is supplied by two separate energy circuits with a 22.2 V 6-cell battery with a capacity of 5,200 mAh, which allows the car to operate in high performance mode for over an hour. For the measuring technology and the computer, an external power supply unit with a voltage range of 6-24 V can be used. 

Engine

The propulsion engine of the prototype is a high-torque brushless motor with cruise control that allows controlled forward and reverse driving, as well as braking in both directions, even at low speeds. The steering system is provided by a digital servomotor used in model racing. It has a high actuating power at low operating times, which ensures precise, fast steering action. 

Computers

The Formentor miniatures are equipped with a miniTX board. This includes an Intel Core i3 processor, 8 GB RAM, a fast 128 GB M.2 SSD hard drive and an NIVIDIA GeForce GTX1050Ti graphics card. In addition to two Gigabit Ethernet ports, the board also has several USB 3.0 interfaces and a USB-C port. Furthermore, a Bluetooth and a WLAN module (IEEE 802.11ac) is available. The communication interface with the vehicle has an additional Arduino micro, so that every single cell voltage of the batteries can be monitored. 

Sensors

The sensor set is pretty close to a real car sensor set. The whole pack consists of the following components: 

• RPLIDAR A2 (front, > 180 field of view, detection range < 6 m, update rate 10 Hz).

• 130° mono video camera (front).

• 80° mono video camera (back).

• Ultrasonic sensors (three in the back, one on the left, one on the right, detection range < 4 m, update rate 40 Hz).

• 9-axis motion tracking sensor to measure acceleration and angular rates.

• Wheel speed sensors to measure the speed of the car
