From the standpoint of an electrical engineer, this remote is easily one of the best bargains for model control I've seen in a gemote 1 Two Rocker Switches - for enabling forward, stop, and reverse on two different, independent control line schemes.

Each switch also has axle-holes for creating your own custom "joystick". The only drawbacks are the battery life which is good, but less than I would have personally liked and the range control gets fuzzy about a room-length awayalthough the range could be low batteries, also However, for the amount of easy-to-learn and understand features, easily configurable as needed, even on the fly, this little remote is definitely an awesome value if you want to control mobile, working models.

This handset works very well for anything except trains, because of its lack of speed control. For cars and other non-variable contraptions, this remote would be a great starter to RC Lego. Controls are very simple and easy to learn. Extremely easy to use and reasonably priced, I recommend this set to every Lego fan!

It's an odd thing to have to say, but, I got this item brand new off the website, plugged in brand new batteries, Duracell, and, Nothing, Nada, Zip, Zilch. Hit the controls and the green light didn't so much as flicker. Batteries maoe brand new Went to the store, grabbed some Rayovac Batteries, plugged them in, and works great!

I ordered 3 of the power functions for my son for Christmas. Couldn't get this one to work, phoned the help line; temote out Duracell brand batteries tend not to work in Lego battery-powered items.

Switched to another brand and voila, works like a charm!

Apr 04, †Ј Learn how to build a remote controlled Rover car with Lego Mindstorms, with an Arduino СbrainТ, which can be remote controlled via Bluetooth with a phone. This guide uses parts from the Steering rover example on elvalladolid.com It is also inspired by the NXT Dune Buggy.

It only takes a minute to sign up. Connect and share knowledge within a single location that is structured and easy to search. In WeDo 2. And having a single caster wheel with narrow tire at the back of the vehicle, not connected to the motor.

Yoshihito Isogawa:. I have followed Aaganrmu's suggestion thank you and have tried to build a simple vehicle using ratchet instead of caster wheel :. Unfortunately, it doesn't work well. There is too much friction - on the axles of all 3 wheels and on the rubber band.

And I feel that my Scratch program can be improved too, since it is not very responsive to user input when touching the 4 green arrows :. Start out with a three wheeled vehicle, with two wheels in the front and one smaller wheel with less traction than the front wheels in the back. All wheels need to be fixed. One of the front wheels is attached to the motor. This might need to have some gearing to get an appropriate speed.

The other front wheel is unpowered but can only rotate forward by adding a ratchet :. Driving forward the vehicle will more or less move straight, guided by the rear wheel. Driving backwards the ratchet will engage, stopping one wheel. The vehicle will now turn. Steer that is exactly about that. When it drives forward it goes in straight line, when it drives backward it then turns to one side.

I've also added distance sensor and made it fully autonomous - whenever it sees obstacle it goes back, turns, changes direction and continuous driving. One motor and a caster wheel will give you two degrees of movement but will not be steerable. If you can build a differential, then drive two wheels with the motor.

If you have limited gears, then drive one wheel, have an idler wheel and a caster or simple skid arrangement. You can get more interesting behaviour by having a bumpbot, that simply reverses the motor when it detects an obstacle. See the Wikipedia article on casters , but there is a strong relationship between wheel diameter and how high the caster should be. And the surface area of the wheel and the mass of the load drive the how easy and fast things swivel. It's an interesting engineering trade-off, and I've never been able to make a perfect caster, even with lots of Technics parts.

I now have reasonable respect for those people who design the casters into the everyday things we use without considering how difficult these trade-offs can be. As in, it isn't an intractable problem, but the problem domain is extremely sensitive to small changes.

Start with a skid first, and an easy, smooth surface to see if you get the basic behaviour you want. Finally, you may get more interesting behaviour by ramping or stuttering motor direction and speed a little on obstacle sense. This is a cheap way to introduce some more randomness into the system.

I designed some WeDo 2. This one uses a system of gears to alternately drive the left or right wheel of a differential drive robot, depending on the turning direction of the motor.

Another idea is making a steering vehicle similar to the one shown in the WeDo App, and involves directly driving a pair of wheels, and having two steering wheels that act as a caster with limited swinging movement.

That way, when the motor pushes the vehicle forward, the steering wheels are forced to stay straight and the vehicle goes straight; when the motor drives the vehicle backwards, the steering wheels will be free to rotate a bit, and the vehicle will steer.

Active 2 years, 6 months ago. Viewed 10k times. Also motor rotating direction can be toggled remotely. I am thinking of having 2 wheels with wide tires in front the vehicle, connected to the motor. The caster wheel would roll straight, when the vehicle drives forwards.

But when driving backwards, it would snap to a certain angle. Yoshihito Isogawa again. Improve this question. Alexander Farber. Alexander Farber Alexander Farber 1 1 gold badge 1 1 silver badge 11 11 bronze badges. Add a comment. Active Oldest Votes.

This can be done without a caster wheel as well: Start out with a three wheeled vehicle, with two wheels in the front and one smaller wheel with less traction than the front wheels in the back. The other front wheel is unpowered but can only rotate forward by adding a ratchet : The back wheel is unpowered. Improve this answer.

This is even better idea than the caster wheel, since I can change the turning degree by rolling back shorter or longer periods of time Steer that is exactly about that When it drives forward it goes in straight line, when it drives backward it then turns to one side.

There is full build instruction in the app. Kamil Dziedzic Kamil Dziedzic 1 1 silver badge 2 2 bronze badges. By steerable I meant being able to reach almost any point at the surface. My problem is to understand and build such a caster wheel, which would snap to an angle, when rolling back.

Well, by steerable I mean likely to reach any point in an area. You won't get much stochastic behaviour, even with a caster. I've added a link to my answer that may help you decide what pieces you have are best for a good caster design. Daniele Benedettelli Daniele Benedettelli 31 2 2 bronze badges. Very nice! Thanks for sharing and for taking the time to expand this into a complete answer.
