Hello guys Crawler tank track/4 wh drive motor with suspension for all terrain .
Aim RC controlled robot for small holding / gardening use. To tow loads : grass cutter / wheel barrow etc Actually for allotment society market
Has anyone got a design showing how to put suspension to drive wheels ? elec scooter design ? What springs.
Recommend where to get suitable low rev high torque motors from ? Pair windscreen motors ? Invalid car motors ?
Made diy tank track from old cycle tyre / nylon bolted to standard chain ( so rigid along its length / meshing with 200mm nylon casters pitch drilled as drive socket.
I think it could be a low cost " recycle" solution for tank tracks . Happy share this design with anyone could help take it to final real working robot.
Nice idea to use cycle tires as tank tracks
But I’m not sure, if I’d like them to rip off my garden soil when manouvering around.
The easiest suspension would be a connecting bar from wheel to wheel with a pivot-bearing in the middle. Maybe add a tension-roller or something to keep the track tight around the drive wheels.
Hello O’Lampe thanks Do you have any sketches/ diagrams of your suggestion please
Yes going to need intermediate track roller /chassis tensioner.
take your point about mashing up a lawn. But its better than wheels ( load spread) Only crawler speed .
Many have had a diy go at bicycle tyres to caterpillar tracks. Just google it PI “P interest” has one too
One was just a fennner drive belt between same V groove drive wheels ( like car fan belts with cycle tyres screwed to them )
They all suffer the same problem : a long rubber anything is just too laterally wobbly ( excuse me sir no giggling from the cheaper seats !) to stay on the drive wheel in a turn Just peels off.
But this design overcomes that with the chain link beefing the tyre so now its rigid along its length. The nylon screws providing the " sprocket" engagement
I cant believe no one actually make something like this " Robot tractor mini agricultural vehicle". Well they do of course but they are all ride on petrol things designed for USA farms Wish I had help sure there’s a market here ciao Ms O
