An anonymous reader quotes a report from CNBC: The U.S. military is using an unmanned robotic vehicle to patrol around its camps in the Horn of Africa. The remote controlled vehicle is the result of a 30-year plan after military chiefs approved the concept of a robotic security system in 1985. Now the Mobile Detection Assessment and Response System, known as MDARS, are carrying out patrols in the east African country of Djibouti, under the control of the Combined Joint Task Force-Horn of Africa. The area is known as home to a number of hostile militant groups including the al-Qaeda-affiliated al-Shabaab. An operator sits in a remote location away from the vehicle watching the terrain via a camera link which is fixed to the chassis. U.S. military software engineer Joshua Kordanai said in a video presentation that the vehicle drives itself, freeing the remote operator to monitor video. "The vehicle has an intruder detection payload, consisting of radar, a night vision camera, a PTZ [pan-tilt-zoom] camera and two-way audio, so the system will be able to detect motion," he added. One report prices the cost of an earlier version of the military 'drone buggy' at $600,000 each.

Trailrunner7 quotes a report from On the Wire: A federal judge has ruled that robocalls made on behalf of political candidates are protected by the First Amendment and cannot be outlawed. The decision came in a case in Arkansas, where political robocalls had been illegal for more than 30 years. On Wednesday, U.S. District Court Judge Leon Holmes ruled that banning political robocalls amounts to an infringement of free speech protections and also constitutes prior restraint of speech. Political campaigns have been using robocalls for decades, and some states have sought to ban them, arguing that they are intrusive and violate recipients' privacy. In the Arkansas case, the state attorney general put forward both of these arguments, and also argued that the calls can tie up phone lines, making them unusable in an emergency. Holmes said in his decision that there was no evidence that political robocalls prevent emergency communications, and also said that the Arkansas statute should have banned all robocalls, not just commercial and political ones. "The statute at issue here imposes a content-based restriction on speech; it is not one of the rare cases that survives strict scrutiny. The state has failed to prove that the statute at issue advances a compelling state interest and is narrowly tailored to serve that interest," Holmes wrote.
