Applications and Implications¶
Project masterpiece proposal¶
The road awareness system¶
The idea I want to implement and prototype is the device-system that consists from
1. Distance sensors mounted on some kind of personal transportation vechicle to precieve the approximating objects and wirelessly transmitting commands to the feedback reciever.
2. Vibration feedback device "mounted" onto the human body to recieve from sensor transmitter and precieve approximating objects with direction through haptic "skin-mapping".
First device would be accomplished using 3D printing for casing also using composite structure for the vehicle-mount and creating control board for sensors and radio.
Second device would be accomplished using 3D printing for belt-clip casing and some in-place casting for haptic surface also creating the control board for vibration motor and radio receiver.
What will it do?¶
It will give the haptic feedback onto object approximation from behind while riding EUC or any other personal transport including motorcycles and else.
Who’s done that beforehand?¶
Cant find anything similar as haptic feedback to approximating objects for riding utility, but there are some references related to haptics.
What will you design?¶
The transmitter: motherboard for radio breakout and TOF sensor motherboard with casing and monowheel mount.
The receiver: Motherboard for radio breakout and vibration motor with casing and belt-clip.
What materials and components will be used?¶
Z-ABS, Silicone for molds, PCB copper plates, 3x vl53l0x tof sensors, 2x nRFnrf24l01 breakout boards, 3x Attiny1614, 3x 1uf & 2x 0.1uf & 2x 10uf capacitors, 3x”6x1” pin sockets, 2x”2x4” pin socket, 3x”6x1” pin headers, 3x”2x1” pin sockets.
Where will come from?¶
Materials from lab inventory and the rest from vendors.

What processes will be used?¶
3d printing, in-place casting, laser cutting, machining…
What questions need to be answered?¶
How human skin could be mapped in order to perceive direction?
What is the minimal number of points to perceive direction?
What haptic motor should be used?
What number of directions could be mapped using 2 haptic points?
What range field of perception should be and how many sensors are required?
What is the best way to deliver feedback?
What is the latency of the feedback?
What is the advanced version of such device could look like?
How will it be evaluated?¶
Does the system provide robust approximation detection on a road?
Could an EUC or bike rider rely on such a system?
Does the system able to interface a direction through skin?
Is it responsive enough for riding a bike or monowheel?
