Trackers on vehicles?

How can i go and play in my (trackered) company van, with out the boss knowing? I don't think blocking it (if that's possible) will do, because they will think there's a problem, and get it seen to. If the answer is take it out, or part of it, and leave it at home, so they think the van is there, that would probably work, so, i look forward to your answers. Oh yeah, and if you can think of a way they will pay for the fuel, while i'm out playing, i'm all ears LOL.

inspection vehicle

Hi everyone! I'm new here and I come from Belgium (so my english is bad ) I'm working on a school project with 5 people. 2 of them are electrical installation technicians and 3 are Mechanical design technicians. We do all of the electronics, while the housing is made by the Mechanical design technicians. We started on the first of oktober and now we almost finished. The vehicle has a Wild Thumper arduino board, Dension WIRC with 2 camcorders and a wifi stick, 2 LED's, a servo motor and 2 DSMP420 motors with a power of 41W. Thanks to my thesis, I started to have interest for arduino. And so I bought a lot of arduino products like the arduino UNO. And thanks to the opensource of arduino I learned a lot of arduino and tryed a lot of projects. So that’s why I'm also putting my project online. It isn't finished because I still have some problems with the charging of the battery's. I use 10x1.2V battery's with 4.5 Ah in series. And the Wild Thumper stops too soon charging. But I'm working on that. :D It's controlled with the WIRC app that connects with the Dension through wifi, which sends signals to the Wild Thumper. These signals controls the motor's and the LED's. The servo motor is directly connected to the Dension. The vehicle will later be used by the Company Cofely to ride in ducts and inspect cables or even take something with the gripper in unreachable places. We are doing a competition with our project. So could you please like this page and vote for our project Make sure that the checkbox is green! :D Thank you very much You can follow us on fb

Arduino Clinometer for vehicle

I'm building a Clinometer for a vehicle, that will show roll & pitch, and log this data as well as yaw (skid). I'm using a 3 axis accelerometer with an Arduino, and am looking for ideas on improvements. I have the g forces for the 3 axis being displayed in the serial monitor, and am ready to display values on a LCD, but really thinking this should be graphics of a vehicle showing pitch and roll, like the old Jeep Clinometer I had as a teen.

multiple speed setting for an electric vehicle?

Suppose an Ev had to run on different speeds say 30 miles/hr and 40 miles/h and vice versa. So how will the the current and voltage changes according to this situation. Say you have a 400w motor and torque is known already and is calculated according to the required acceleration. In short if you have an Ev and u want to set the ev run on different speeds what are the quantities that have to be checked or monitored (current,voltage) and .If you move from 30 to 40 miles/h what will happen to the variables?

3D Printed Solar Electric Vehicle

Last months, as passive and low energy construction business went down in Romania, I had time to revival an old project - Zero Emission Solar Electric Vehicle. While researching online and off-line for chassis, body and materials suppliers and manufacturers, went to the 3D Printing idea for chassis, body and parts! There are already at least 2 cars printed so, and I'd like to share what I know already and also to learn from you. The vehicles will be modular, also. Hope you will love this idea, when I will have design ready and show it here :)  We might use Open Source Vehicles chassis, but not sure about this, because 3D printing will reduce the need of many parts that are in a classical chassis and body.  Your info brought here and your decent comments will be deeply appreciated. Thank you!

I'm currently working on a mech but I need to get an idea on the interface system, so what would be the best fit for it?

Actually I'm working with a few others on this but (as you would expect) our funding is quite low. Right now however; we're trying to decide what the best type of interface system we could use on our mech (yes a REAL, FULL SIZE, WORKING, Mech.) and so I'm turning to the Instructables community for help. Thanks in advance, Jake PS: If you want in on the project then you can email me ( with a list of skills you believe could be useful in the building process and I'll get back to you asap or if you just have a question about it that's fine to. [edit] And to respond to my first (and currently only answer) thanks for the help btw, the motion tracking is a great idea and would help improve the user interface greatly. However, what I'm referring to when I say 'interface' is how you would control and interact with it, your reply was part of the answer and will (hopefully) be implemented into our UIS (user interface system). Thank you and I hope to get many more answers soon. Jake

Computer AM Radio Controlled Vehicle?

So my school is planning a day for students with disabilities and I figured, heck, lets have some real fun.  So I have two very cool RC cars, each can easily do 40 - 50 mph.  One has been up to 65.  There is one problem, these kids need to be able to control them with the push of one big button.  I cant just solder some wires for the button to my RC remote so what do I do.  I figure I could still do the steering, but I want them to be able to hit the button and transmit the signal to the car to go.  It needs to be limited in power as well, normally I could just stick a large resistor on between the controller and the motor, but I have brushless motors.  These buttons are easily attached to computers and used as keystrokes so is there a way to make a w keystroke output a 25% throttle signal on a 27.255MHz (this is only one car's frequency) AM signal.  It would be nice if it could all be computer controlled so I could change settings to get them just right, and maybe control both vehicles without having to set up two completely separate systems.

Ideal Gear ratio?

Hello i am competing in a design challenge at school. were were each given a 9v 12000 Rpm Motor, the object of the challenge is to build a land vehicle that can go 10m as fast as possible. we will be holding a race on november 3rd to see who has designed the fastest vehicle. anyway my question for the community is using a 12000 rpm electric motor what would be the best gear ratio to use between the motor and the axle to optomise take off speed as well as having a high top speed. (if the gear ratio is to high then the car wont accelerate fast enough to low then the car wont have a fast enough top end) so basicly im looking for that perfect med ground. if anyone here has had much experience with gears and help would be great thanks (PS the vehicle cant be any biger then a vhs case but can be as tall as i want it)

Robot Pegasus design possible? Answered

Ok, so I have another idea that will most likely never get anywhere due to my lack of funds/it not being possible.           What if I made a magnetic track somewhat like a maglev and had a robotic pegasus with electromagnets in its feet. It would also be an ornithopter to get it farther than a few inches off the ground. I would have the magnetic track to have it hover a few inches off the ground for about a minute before and after takeoff to make it less likely to crash on landing and give a minute to text the mayor to not worry about any upcoming pegasus sightings above or around town before taking off.           What kind of horsepower engine would I need to power the wings enough to get sufficient lift (at least 15-20 feet)? And would the electromagnet buffer before landing be significant enough to at least lessen the impact so it doesn't maim/kill you if you crash?           The electromagnets don't seem to me like they would work, but it would still be fun just to hover it to show it off without flying up 20-30 feet and worry about falling. Also, would it make it too heavy to fly if I put in an extra motor to make it walk/run so it doesn't have to be flying to move? I don't really expect this to be within my budget, but it would still be cool.

How to guide a vehicles with two infrared sensors?

I have a robotics project where I need to guide a few robots to specific circles that are at a random distances. On the day it is due I will be given the distance to the middle of the circle and can adjust what ever guidance system I have. There is a budget cap on the project so i would like to use just one or two controlling things for every robot. Now what I was thinking was to set up some sort of IR beacon in the starting square. If I placed two beacons, one at each corner or the square (each circle is a certain distance from each side of the square) I could have an arduino to remotely control them. I hope that makes sense so if you have any ideas or questions that would welcome both. Thanks in advance, Zootsuitman

How to make a magnetically powered/propelled vehicle ?

I'm a freshman in high school doing a Year End Project (YEP) for STEM. My project is a vehicle that is propelled by electromagnetism. I have three main idea's already. Option 1: Completely replace wheels with large magnets with either a North or South charge. Then replace normal roads with railings charged with magnetism of the same polar to the cars. The bumpers could be magnetically charged as well. With all car bumpers being the same polar, it would decrease the chances of accidents. Take into account that this idea has only started growing for the past 2 years so my ideas for the mechanics are not close to completion so I'm leaving those thoughts out. Option 2: keep the wheels but modify them to have 2-3 smaller magnets on the inside of the wheel. By turning and switching on different a polar changing direction between forwards and backwards. Then add the same idea with the bumpers for the same reason. This cuts the cost exponentially. Option 3: Keep the wheels and everything else of a normal automobile except the engine. Replace it with on large magnet that's stationary and a smaller magnet that can rotate or switch between North and South polar's. Possibly instead of only one pair of magnets increase to an unknown number to allow for more speed, braking and acceleration power. Still keep with the bumper idea. I can't seem to find a reason other than cost to get rid of it. Of course the magnets would interfere with electronics. I haven't thought of a solution for that problem as of yet.

What excellent examples in CAD of low drag coefficient pickup trucks exist that are available on the internet?

Vehicles have been designed to minimize the aerodynamic drag with notable success. Production candidate vehicles (such as Aptera, Twike, and Honda Insight) achieving drag coefficients of 0.25 down to 0.11. Solar Challenge vehicles have reached 0.07. Nose cone and fastback upper and sealed or faired lower body designs can achieve significant reductions in drag, and are worth attention. I am attempting to optimize a design for pickup trucks and cross-over utility (CUV) vehicles that are based on the same basic chassis design. Can anyone contribute designs, examples, or sources of information on optimized pickup design? BTW, I am simultaneously searching for a safe design that has the vehicle center of gravity at or below the axle height, as it should be to prevent roll-over accidents. Risk of injury and death are significantly higher in pickup trucks and CUVs than cars, and now pickups and CUVs account for more than 50% of new vehicle sales. This tragic fact needs to be reversed with safer design.
