RoboUniverse, where bots build, teach and sell (pictures)

This robotics trade show, held at the Javits Center in Manhattan this week, included presentations from iRobot and Wolfram Research, along with an exhibit hall filled with dozens of robots.

The floor, which was filled with about two dozen booths, hosted all kinds of robots inside, including robot arms for industrial work, a heavy-duty drone and a roving kiosk by Fellow Robots -- pictured here -- that can lead store customers to the specific items they are searching for.

Universal Robots, based in Denmark, sells robotic arms for assembly lines in auto and pharmaceutical factories. The arms use different kinds of connectors to allow them to weld, glue, suction or clamp.

Brian Kobus, a technical support worker for Universal Robots, demonstrates how to program an arm's motions using a tablet computer.

Here Kobus shows off the tablet remote and its controls.

This is Milo, developed by RoboKind Robots, which is a robot that can assist children with autism to practice social skills.

This $5,000 robot went on sale in January and is used in special-education classrooms and homes.

Milo can dance and walk around to keep children engaged in its lessons. It can also record its conversations with children and has an HD camera to allow therapists to monitor students' progress and participation.

Baxter, by Rethink Robotics, is a type of robot created to operate simple, repeatable tasks next to people in a production line without the need for safety cages. Here's 10-year-old Ishai Benari using a Baxter's clamp to pick up a calculator.

Baxters can be used for packaging, material handling, line loading and other simple tasks. In this demonstration, it uses suctions to pick up and move plastic pieces and a metal sheet.

Doog created the robotic version of a duckling. You stand in front of it, press a button and it will start following you around once you start walking. These robots are used at malls to follow around salespeople with banner ads, but Doog may also use this same technology in the future for shopping carts, stretchers or wheelchairs.

The boxy QC Bot can deliver all kinds of products around a warehouse or manufacturing plant. So far, the robots have found a place in hospitals, safely delivering drugs from a pharmacy to doctors and nurses.

This robotic arm by Kinova Robotics can be placed on a power wheelchair to help disabled people or those in rehabilitation grab and manipulate objects around them.

AeroCine shows off one of its drones, which are used for film production, capturing news events and inspecting real estate.

Acorn executive Barry Braunstein presents a first-responder robot built by RoboteX that his company helped develop. The bot can be utilized for hostage situations, fires and other emergencies.

Tyler Chaulk, right, a "residential roboticist" for Newbotic, explains the uses of a small robotic arm by Energid to an expo attendant. The arm, he said, can be used for R&D, parts inspection and light manufacturing.

JD is made from a robotics kit sold for $430 by EZ-Robot, which targets these kits for science and technology learning. After clipping the robot together, JD can walk, grip objects and see around it.
