Processional Shock Absorption Robot Tank Car Chassis with DC Encoder Motor for Arduino / Raspberry Pie, Tracked Suspension Absorbing Vehicle, Remote Control Track Crawler Damping Vibration Caterpillar

I put this together pretty easily. And am super satisfied with how it runs. It is a great project for price and if you're trying to work with PWM signals / a drivable device this is perfect.Cons: the directions could use some work but it wasn't too difficult to figure out some parts.Pros: when you're done you have sturdy tank body that is surprisingly agile.

Although build quality seems ok, kit was completely missing crucial parts (springs nuts, bolts). Disappointed that I could not build the kit and wasted my money. I doubt the seller will send the required parts. Would not recommend this kit from this seller.

While the printed instructions included in the kit are vague, the website offers a very good tutorial and terrific instructions.Very impressive and performing tank chassis when fully built.The shock absorbing suspension is simple and should allow a load capacity of 5-7lbs and allow for sufficient articulated movement.

I must admit that I have not completed this project. Since I can add to the basic structure, I consider this be one of the challenges that I most crave in building these machines.

Don't expect thorough instructions. I had to stop and think it through a couple times but I got the chassis assembled in about 2 hrs. It did not include the 2mm retainer screws needed to keep the wheels on the axle, so consider ordering a set (10 total). They'll need to have a wide head or washers. Other than the missing screws, I was pleasantly surprised that everything went together well.As far as durability, I think the frame is a bit on the flimsy side - I plan to add some bracing to keep the track frames rigid. The tracks are some kind of plastic/ABS and they are decently strong, although time will tell if they hold up, and they have zero traction on smooth floors. It is not fast at all but it has reasonable torque. The spring suspension is very firm - unless you have a heavy payload, it's going to be a bumpy ride.
