Helping Hands RL Environments

License

This package contains various simulated robotics environments used for research in the Helping Hands lab. The majority of these environments entail a robotic arm armed with a paralel jaw gripper executing a series of manipulation based tasks. For a full list of the tasks currently implemented see below. The core simulator used for most tasks is PyBullet but a simple numpy based simulator is included for quick prototyping.

Environments

2.5D Environments

block_picking: Pick up all blocks.
block_stacking: Pick up blocks and place them in a stack.
block_adjacent: TODO
brick_stacking: TODO
pyramid_stacking: TODO
house_building_1: Build a house structure with a block stack and a small triangle roof on top.
house_building_2: Build a house structure with two block bases and a large triangle roof.
house_building_3: Build a house structure with two block bases, one brick in the middle, and a large triangle roof.
house_building_4: Build a house structure with two block bases, one brick in the second layer, two blocks in the third layer, and a large triangle roof.
house_building_x: TODO
improvise_house_building_2: Build a house structure with two random shape bases and a large triangle roof.
improvise_house_building_3: Build a house structure with two random shape bases, one brick in the middle, and a large triangle roof.
