首先创建一个Conda环境，名字为robobrain2，python版本为3.10；

然后进入robobrain2环境，执行下面命令：

conda create -n robobrain2 python=3.10 conda activate robobrain2

下载robobrain2代码到本地：

git clone https://github.com/FlagOpen/RoboBrain2.0.git cd RoboBrain2.0

2、安装依赖库

4、模型推理

主要包括：图文问答（支持思考模式）、目标检测（视觉基础能力）、可供性预测（具身认知）

操作轨迹预测与规划（具身决策）、具身导航任务

在首次运行时，需要下载模型权重的，比如RoboBrain2.0-7B：

备注：需要在终端输入“huggingface-cli login“命令，然后输入“Access Tokens”进行登陆

而且下载RoboBrain2.0的模型，需要先签名认证，才能下载的（对应下面图片的“verified”）

比如：https://huggingface.co/BAAI/RoboBrain2.0-7B/tree/main

The adult is wearing a blue garment, indicating a larger individual, while the child is clad in a red cap and a striped garment, suggesting a smaller presence. The child's hand is positioned near a banana peel held by both individuals.\n\nIn terms of spatial analysis, the child, identifiable by his distinct red cap, is visually closer to the right side of the image, while the adult male is towards the left side. The banana peel, grasped by both, is centrally located, bridging their interaction visually.\n\nAnalyzing the elements around them, they appear seated on a stone surface against a wall, which serves as the backdrop. The environment suggests an outdoor setting, reinforcing the casual nature of their interaction.\n\nThus, based on my visual-spatial reasoning capabilities, the child, wearing the red cap and striped outfit, is the one interacting with the banana peel, evidenced by his proximity to it and the distinct red accessory he wears."}

The adult appears to be sitting next to or behind the child, engaged with them. The child\'s position is slightly turned away from the observer, creating an interactive moment.\n\nAnalyzing the spatial arrangement, the banana is held in such a way that its curved shape and peel are prominent features in the visual field. This positioning allows for a clear identification of the fruit\'s location within the frame.\n\nThe task requires identifying the banana\'s location relative to certain elements in the visual input. Given the child\'s direct interaction with the banana, it can be determined as being held by the child. From the visual context, the banana is indeed found within the child\'s grasp. Therefore, based on the observed details, the answer to the question, "What is the banana?" is that it is positioned where the child is holding it.'}

{'answer': '[561, 224, 623, 303]', 'thinking': 'From the visual input, the object is recognized as a white mug, with a cylindrical body and a round handle on its right side. The approximate size suggests that it\'s about 10cm tall and has an opening wide enough to hold a standard coffee cup\'s capacity, making it around 7-8 cm in diameter. The mug appears to be made from ceramic or similar material, inferred by its smooth surface and uniform color. It rests stably on what seems like a wooden table surface, with no immediate obstructions nearby.\n\nMy end-effector, capable of joint control manipulation, is designed to grasp objects securely. Its design allows for precision in grasping curved surfaces and handles up to a certain height and thickness. The handle on the mug presents a suitable engagement point due to its shape and size, which my gripper can wrap around effectively without slipping.\n\nThe current task is to "如何抓住杯子," which involves identifying the most secure area to grip the mug. Given its position on the table, the handle stands out as the best affordance area because it provides a stable, protruding edge that is easy to approach and firmly grasp. \n\nTherefore, the mug\'s handle affords an optimal interaction point. This choice is supported by both the visually confirmed handle dimensions compatible with my gripper\'s capabilities and the requirement to accomplish the task efficiently.'}

You are a robot using the joint control. The task is "伸手去拿红色的瓶子". Please predict up to 10 key trajectory points to complete the task. Your answer should be formatted as a list of tuples, i.e. [[x1, y1], [x2, y2], ...], where each tuple contains the x and y coordinates of a point.

Prediction:
{'answer': '[(145, 123), (259, 168), (327, 136)]', 'thinking': "From the visual input, the target object, a red bottle, is clearly identified resting upright on a black tray positioned towards the right side of the scene. My current end-effector position is to the left of the scene, near several other objects like cups and plates that do not obstruct the path directly. Notably, there’s ample space between my initial position and the red bottle, allowing for an unobstructed path.\n\nMy joint control system enables me to generate smooth trajectories. I will plan a sequence of movements starting from my current location, moving towards the red bottle. Given the open field, I can calculate intermediate points ensuring a direct approach without collision with nearby objects. Up to 10 key points are suggested but fewer may suffice given the straightforward nature of this task.\n\nThe task involves reaching and grasping the red bottle. The trajectory must be efficient and direct, originating from the initial position on the left and terminating precisely at the bottle. Each segment of the motion should ensure clearance from surrounding objects, minimizing potential interaction. This requires careful placement of key waypoints to guide the motion smoothly.\n\nVerification confirms the path's logical progression. The sequence of points is checked to ensure they maintain a safe distance from obstacles while advancing toward the red bottle. The final point must accurately target the bottle's handle or body for a successful grasp.\n\nTherefore, based on this comprehensive visual analysis and planning, the key trajectory points to reach the red bottle are determined as [(145, 123), (259, 168), (327, 136)]. These points form a viable path from the initial position to the target while respecting the environment."}

The empty space between them is crucial for identifying potential placement points. This area lies flat on the surface and offers an unobstructed path, making it an ideal candidate for placing additional cups.\n\nMy advanced visual processing capability allows me to segment this gap visually, ensuring that any identified points will lie entirely within this region, avoiding edges or other objects nearby. It is essential to confirm that there are no physical obstructions like shadows or reflections, which might affect perceived space availability.\n\nThe task requires determining several spots within this vacant area. I start by verifying its dimensions, confirming the gap's width and height. Next, I select multiple points, spread evenly across the free space, to ensure diversity and coverage across the entire visible region, simulating different spots to place an additional cup effectively.\n\nEach identified point undergoes verification to ensure it falls strictly within the boundaries of the open space between the cups. Distinctness among points is also confirmed, avoiding overlap and maintaining separation.\n\nTherefore, through direct visual analysis, combined with my cognitive capabilities, the identified points within the vacant space are [(334, 320), (305, 316), (369, 315), (389, 317), (314, 313), (350, 314), (378, 313), (325, 317)].
