I am new to robotics and such. I have this thing I want to do, but am not sure of all the components I would need. If anyone could help me, I would greatly appreciate it.
So here it goes…
I need a small 12 inch disk to move from point A to point B (about 5 feet) then back and forth on a rail that will be a C Channel aluminum with bearing inside (so it will glide). I want to disk to be mounted on a housing, that will hold the motor/battery inside, and the motor would have a wheel that would sit on top of the rail, thus pushing the unit forward. Once it hits one end, I would need it to automatically go back. (ideally I would like the 12in disk to rotate 180deg to face the way it is going.
Im very visual, so maybe im not explaining this perfectly, plus english is not my first language.
If anyone is interested in helping me with this, reply here or email me at [email protected]
Can you provide a drawing or sketch? Do you already have any of the parts? If you can explain what you envision as the en result, or why you are doing this project it might help us better suggest specific products.
absolutely right, I will draw it up on Paint or something, and show you what I need.
Basically, I want a Toy Soldier to be on this round plateform, and I want it to go back and forth like if it is guarding a door. As mentionned, I want it to be on a small rail system about 1x1 inch max 1.5x1.5 inch by 5 feet long or so. I want the plateform (withsoldier) to be the power unit, I dont want a strap system, or screws system with the motor at the end. because eventually, I would like to add 45deg turns, 90deg turns etc. As soon as its drawn up, ill post it back.
Ive seen builds with belt and pulley, but since I want my platform (toy soldier) to be able to eventually furn 45deg and 90deg rail system, it has to be intdependant. Like a racetrack, the car needs to be free to turn as the track turns…
here is a sketch up on paint. Maybe this will clarify. On this example, its a straight track but as i said, i want the track to eventally turn and be limitless (20ft, 60ft) with bends 45deg. 90deg and straights.
When you press reply, there is a section at the bottom “attachments” which is closed by default.
The idea proposed would have the timing belt as the track, so you can cut it and make it whatever length you want.
yes lenght wise and linear wise a strap is fine. But If i want my track to turn 90 degrees, or lets say build a oval track…how would that pully be able to turn and follow the form of the track ? I beleive pulleys are only good for linear tracks.
I just found on your website the robotshop.com/ca/en/2wd-begi … assis.html. This is what I would need, I would place this on top of a track with a track glider system (ballbearing) to stay on track, the rubber wheel would sit on top on propulse the unit. I could then sit my toy soldier on top of the unit.
About this kit tho…My toy soldier would weigh in at around 3-5lbs. are these motors high torque ? I also need this unit to be speed adjustable, i want it to go like walking speed…
so im guessing i would need…
1- stronger high torque motor
2- 6v rechargable batteri
3- speed control (potentionmeter ?)
4- and maybe a way to have the unit spin 180degrees when it hits the end of the track…
The motors on that platform can’t really be upgraded. The higher payload robots are quite a bit larger and more expensive, so you might consider creating your own base using a propulsion system: robotshop.com/en/propulsion-kits.html
You would need a normal caster wheel (or two) for balance.
You would need a microcontroller, battery, charger, motor controller and sensor(s).
Having the robot automatically rotate 90 degrees (or 180) either needs to be done using electrical components or via coding (suggested).
