Delivery robots are not only convenient and cost-effective, but they also have environmental benefits. They can reduce traffic congestion and greenhouse gas emissions by replacing cars and trucks for short-distance deliveries. They can also improve access and equity for people who have mobility issues or live in remote areas.
However, delivery robots also pose some challenges and risks, such as safety, security, privacy, and liability. They need to be regulated and monitored to ensure they do not harm or interfere with other road users or pedestrians. They also need to be protected from theft, vandalism, or hacking.
