I would like to clarify the details about the power unit and the battery.

Motor type, parameters, drive system wiring diagram, battery type, its capacity, cooling of electric motor and battery? How is the capacitance of the battery cells balanced?

These are essential issues for an electric vehicle, since they directly affect its reliability. The battery capacity and range (120 km) give an answer to the economic efficiency of an electric motor compared to an engine. In other words, the cost per kilometer and the cost of maintenance.

For driver safety within the M1 certification, what are operation principle and type of airbags used? In particular, how does the airbag operate with a wheelchair fixed inside the car?

The stiffness and strength of the wheelchair fastening should be the same as for the car seats that can withstand the collision impact. The airbag triggering towards the driver should be compensated by head restraints to prevent a fracture of the cervical vertebrae (neck fracture when moving in the opposite direction - "through the back").

Thank you for your reply in advance. Such information increases confidence in the product.
Unimobile Team:
Our prototype uses a 28kWh air-cooled synchronous motor.

A Li-ion battery (96 V and 27 kWh) is applied with a conventional balancing scheme like in most electric cars. Currently, the prototype has two front airbags. Additional airbags are extras.

We have designed a special wheelchair equipped with a head restraint, which fully complies with the standard characteristics of a car seat, and is intended for use when driving. The special lock reliably fixes a wheelchair inside the car.

There are a lot of people with disabilities who do not have right hand, who were born like this or it happened due to injury. I think that for the prototype and serial production car it is necessary to think about the usability for left-handers: either by putting the joystick to the left of the steering wheel, or make similar solution to other production cars, that equipped with a similar controls for left-handers. For serial production, it is good to have some vehicles for left-handers, so that a disabled person does not have to additionally modify the vehicle controls.
Unimobile Team:
There are no vehicles for left-handers or right-handers. The joystick can be installed on any side.

It would be nice to have a second row of folding seats mounted on the left and right rear sides of the car to make a vehicle more functional. Idea of electric car is a bit frightening. What's wrong with the internal combustion engine? It seems to be more reliable, practical and cheaper.
Unimobile Team:
Idea of having additional seats as an option is currently under consideration. Initial idea was to build a petrol version of the car. Our attempt to fit the combustion engine and automatic gearbox in the available dimensions of the prototype was unrealisable.

For people with disabilities who are not wheelchair users, but have mobility issues, it would be nice to equip vehicle with two standard seats. At the rear — shopping trolley which you can use to store your groceries while shopping, and then to lift it into the car with a ramp lift (useful for many people, especially aged persons and persons with various diseases, who are not allowed to lift heavy objects).
Unimobile Team:
You can choose any suitable trolley for you. The car is designed to install two regular seats with turning mechanism.
Andrey Mazenkov, Saratov, Russia
Can a wheelchair user, when outside the vehicle, wipe the glass, change the battery, open the hood, inflate a tyre, change a wheel, open and close the rear doors and the ramp lift manually without a remote control, and being inside the car, to take something from behind, to turn 180 degrees?
Unimobile Team:
You mention all the things that any driver should be able to do (check), regardless of having a disability. This is a necessary set of skills required to obtain a driver's license. You can open the rear doors without a remote control. To get something from behind is challenging for any person. 180 degree turn is possible.

I watched all the reports, but I haven't heard about cruise control availability. I think it's a very important feature, especially for people having spinal injuries.
Unimobile Team:
Сruise control is implemented as an option on the joystick of the vehicle.

Is there an autopilot in case of an emergency, or if a person suddenly feels bad? I think it's interesting to make such an emergency button of transfer control to the car, when a disabled person abruptly feels sick. This button should be arranged exactly on the chair, which can be connected to control via cable. In an emergency, in order not to search such a button for a long time and not fuss, you can press it on the armrest of the special chair being supplied with the vehicle as a set. The button should be unlocked with a fingerprint. This is my idea. It would be an excellent option. This button will immediately call for emergency medical service by a special signal and provide immediate satellite tracking.
Unimobile Team:
One of the tasks we set is the minimum cost of the car for a user. Autopilot option will increase the vehicle cost. As for an emergency call button, it will be implemented in the production vehicle.

Hello. Maybe I've missed something, but it seems me that the seat belts are two-point, i.e. a driver and a passenger are fastened only through the chest without the waist? One can easily solve this problem by adding one more sliding buckle to the belt. So, first, the driver takes the lower buckle with his/her left hand, pulls the belt down along the counter and fastens it in the left locking retractor on the armchair. Then he/she takes the second (sliding) buckle on his/her already fastened belt with his/her right hand and pulls it over the hips to the right locking retractor. Three points are provided. But you have to unfasten yourself from both sides :)
Unimobile Team:
The vehicle is equipped with a 3-point seat belt system.

To place a solar panel on the entire roof. And to provide an option of combing the car batteries and the seats into one power system. You never know. On the front panel (where conventional auto has radiator guard), a non-contact charging socket would be very requested. For example, if such a car is parked in a designated area, the disabled person goes back, presses the key fob button and the front panel (in any way, from lever to just inflatable) moves out to the remaining 5−15 cm and presses against the panel of a contactless charging on the wall. By the way, for the same reason it is worthwhile to rearrange the charging socket from the front bumper (inconvenient in a tight garage) or at least duplicate it on the rear bumper.
Unimobile Team:
As we've already mentioned, any additional option should be feasible. Solar batteries are not efficient enough in our climate zone. The charging areas for cars for disabled people should be equipped with non-contact charging. The position of the charging socket was designed as in most electric vehicles. By the way, it will not be a problem to rearrange the socket.

Hello. I haven't seen on the video the function of adjustment of convenient position of the steering wheel in relation to the driver's seat.
Unimobile Team:
The production vehicle will have adjustment for steering column rake and reach.
Pyotr Gavrilov, Nizhnekamsk, Russia
1. Navigation device. And environment controller. Otherwise, where to park a car in the center of Moscow, for example, where every corner is occupied? 2. Additional side lights. When driving at night, you need to highlight the turning from the direction you are going to turn. Disabled people are much more difficult to navigate in space than other citizens. Or the lights (2 pieces — the right and the left) should be set on the roof, or the option should be embedded into the right-left panels, with mandatory separate manual and electronic controls.
Unimobile Team:
The navigation system will be available in the basic version of the vehicle. As for environment controller, it's an expensive option. Turning side lighting can be an option.
Mikhail Antonov, Kharkov, Ukraine
Does the rear platform-ramp have two modes? Departure of the wheelchair to the asphalt (complete lowering) and driving to the curb (lowering the pantograph only to the height of the curb, or tilting of only one platform is possible?)
Unimobile Team:
The platform can be lowered both to a flat asphalt and a curb with driving to asphalt.

Perhaps for people with weakened hands, it is more convenient to arrange the control joystick directly on the steering wheel.
Unimobile Team:
The design implemented in the prototype was considered optimal. The production vehicle will have both options.

Everything is awesome! Is it possible to make the ground clearance floating, because of the quality of the roadbed (there are bumps and potholes, as well as ramps to the country road, or in winter, when snow is not removed by the road service, which makes further travel to the destination rather difficult? Car alarm with duplicating SMS messages to the owner's phone + auto tire inflation to provide the ability to drive in difficult conditions.
Unimobile Team:
The ground clearance on the prototype is 140 mm, which is higher than the average in this class. Changes in clearance will lead to higher prices. This is a city car and there will not be tire inflation functions. Users can select alarm system on their own.
