Development of Low Cost Radio-Controlled Cars Dynamometer

A dynamometer, often known as a dyno, is a tool used to concurrently measure the rotational speed (rpm) and torque of a moving motor or engine to determine the power output at any given moment. A dynamometer is utilized as part of a testbed for numerous engine development tasks in addition to measuring the power produced by the engine or motor. This study aims to develop a low cost Radio-controlled (RC) cars dynamometer using the concept of small scale chassis dynamometer with size range from 1/20 (12cm-7cm) to 1/10 (35cm-43cm) which can establish the value of RPM, torque and horsepower. In this study, a dynamometer is developedusing aluminum profile with size 20mm x 20mm for the chassis with a N35 magnet with size 10mm x 20mm that attached to the gravity roller 50mm x 200mm. The LM393 Hall effect magnetic sensor that connected to Arduino Uno R3 will detect the rotation of the magnet at the roller to calculate RC car RPM, Torque and Horsepower that will be displayed on the Arduino L2C Serial LCD. The result is verified using tachometer to compare the value of the RPM, Torque and Horsepower which provide the percentage error of 0.107%. This dynamometer has potential for STEM activity in the Design and Technology (RBT) subject for student learning in school.

INVESTIGATION OF USER INTERFACE OF GYRO-SENSOR-BASED HAND GESTURAL DRONE CONTROLLER

Joystick controllers are used mainly for modern civil drones. However, joystick controllers are non-intuitive and require two hands to be used simultaneously. Therefore, although single-handed drone controllers using a joystick and hand gestures have been introduced, they have only replaced the right stick of the joystick controller with gyro sensors. While this approach retains interface continuity with conventional joystick controllers, it is not user-centric. Therefore we propose a gestural drone controller based on hand gestures, and compare it experimentally with conventional controllers, including an investigation of the effective differences depending on the user’s joystick experience. We separateparticipants into expert and novice joystick groups to investigate the joystick controller experience effects (e.g., radio-controlled cars, game consoles) for each controller type. The conventional joystick controller is found to be superior to the conventional gestural controller for five out of nine criteria, and superior to the proposed gestural controller for three out of nine criteria. The proposed gestural controller is more natural than the conventional gestural controller. There tends to be an interaction effect of the joystick experience and controller types, considering the naturalness of the controller.

MÉTODO PARA GENERAR HIDRÓGENO A PARTIR DE RESIDUOS DE ALUMINIO, PARA ALIMENTAR LA PILA DE COMBUSTIBLE DE UN COCHE DE RADIO CONTROL

Most of radio controlled cars with Fuel Cell on the market store hydrogen in pressurized cylinders or metal hydrides. In this article, the possibility of generating hydrogen inside the vehicle, at a constant flow rate, from aluminum soda can rings, in alkaline solution medium and by isopropyl alcohol regulation, is proposed. The alcohol helps to eliminate the NaOH particles transported by the hydrogen and likewise to keeps the flow rate constant over time. A theoretical model has been developed to predict the hydrogen flow rate generated as a function of the molarity and temperature of the solution, as well as the purity and dimensions of the aluminum plates. Subsequently, the model has been validated experimentally from test plates and the flow rate and purity of the hydrogen obtained has been analyzed. Finally, a radio control car with Fuel Cell was designed, adding the filters and elements necessary for its correct operation. Main contribution of this study is the use of isopropyl alcohol for flow rate regulation and the control of the purity of hydrogen.

Flights of Fancy: Products in the Unmanned Systems Marketplace

i»?Radio-controlled (rc) cars, boats, planes, and helicopters have been around for decades, but the emergence of consumerfriendly quadrotor copters has changed the game completely. This year, for the first time ever, the International Consumer Electronics Show (CES) showcased a full range of related products in the Unmanned Systems Marketplace. The CES spotlight came at a pivotal time for the small unmanned aerial vehicle (UAV) market, as headlines touted drones as the gadget of the year and aviation authorities wrestled with regulatory questions.

Development of a Small-Scale Research Platform for Intelligent Transportation Systems

In this paper, we propose and develop a small-scale research platform for intelligent transportation systems (ITSs). Our platform has four main parts, i.e., an arena, an indoor localization system, automated radio-controlled (RC) cars, and roadside monitoring facilities. First, to mimic traffic environments, we build an arena with a wooden floor, mock buildings, and streets. Second, to facilitate feedback control for trajectory following, an indoor localization system is set up to track the RC cars. Third, both autonomous driving RC cars and human driving RC cars are developed, based on an automated RC car design. The automated RC cars can receive control signals from a computer through an Xbee RF module and control the front and rear wheels through motors. A new control algorithm is developed to allow the RC cars to track predefined trajectories. Finally, we implement an example of roadside monitoring, which uses a fish-eye camera associated with advanced video processing for image segmentation, object identification, and tracking. Experiments are performed to demonstrate the effectiveness of the designed platform. We also discuss possible ITS research problems that can be studied in this testbed.

VSS Control of Distance between Vehicles in AHS for Autonomous Radio Control Car using VSS Obserber.

The car has various problems which is the traffic accident, congestion, pollution, and the resource consumption, etc. However, recently the realization of AHS (Automated Highway System) which is one of ITS (Intelligent Transport System) is enumerated as an effective solution of these problems. This paper describes the effectiveness of the discreat-time sliding mode control system in the simulation and the experiment. Two radio controlled cars of 1/10 scales on the market are used for the experiment device. The radio controlled car is autonomous because it is equipped with the microcomputer which printed out the program of control system, ultrasonic sensor for measuring the distance between cars, and the photo transistors for steering wheel control. It makes two radio controlled cars ran by steering control on the oval course. The distance between cars is observed by VSS observer. And this paper verifies it's effective.

A medium resolution intelligent video camera

The most popular method for abstracting visual information from video images is based around image grabbing techniques. This is expensive, bulky and quite often too slow. It also requires the use of large amounts of processing power. There are a number of applications, ranging from intelligent toys to machine vision and security applications which need either low cost video images or ones that can be digitally manipulated. The main criteria for the camera described was its manufactured cost-below $20. If had to be easily mass produced and small enough to fit into mobile toys, such as radio controlled cars.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
