Sealed-System Bucket Loader Cleans Messes in Dangerous Places

 

Cleaning up after a disaster is hard and dangerous. But the ROEBL project is trying to make it substantially safer by removing the human operator from harm’s way. The Remote Operated Electric Bucket Loader had a big double-fenced, cement barrier play area set up at Maker Faire and [Justin Gray] walked us through the project which concluded with a demonstration of the hardware.

For now the operator does need to be on site to see what the loader is doing, but a first-person video setup is planned for the future. Still, removing the operator from the jarring experience of riding inside is an improvement. And the sealed nature of the electric and hydraulic systems mean that it can operate in areas inundated with liquids like water or oil.

The video above has a 90 second demonstration at the end (while we all laugh like children at what really was a giddy display of power being thrown about by a handheld controller). The ROEBL website has a gallery where you can see the conversion process that started with a standard diesel machine.

An Awesome Electric Bike

Converting a motorcycle to electric is always a favorite project of ours, and [Peter]‘s build is up there with the rest of them.

The bike is a 2002 ZX6E he bought from a salvage shop. It had been parted out over the years and for $250 this very light aluminum frame made the for the perfect electric conversion frame. After learning MIG welding from his brother, [Peter] cut up a few plates and built a motor mount for his new 4.2 kW power plant.

The controller is a 300 amp IGBT he found on eBay, with an extraordinarily sturdy looking circuit built into an ammo box. The motor from the bike was replaced with 16 60Ah LiFe cells providing 52 volts. [Peter] also built his own battery management system using a Cypress PSoC 3 microcontroller and a beautiful custom PCB.

It’s still a long way from being finished, but already [Peter] has a great looking bike and an awesome weekend project on his hands.
