Overview 2 2.2 Basic Pioneer Platform Pioneer 1 is a small, mobile robot developed by Kurt Konolige of SRI International and Grinnell More of Real World Interface, Inc., and is available exclusively through Activ Media, Inc. The basic Pioneer 1 Mobile platform contains all of the components for sensing and navigation in a real-world environment, in[...]

Gripper & Experimenter’s Module 3 Figure 1-2 Pioneer Gripper side view. Figure 1-3. Pioneer Gripper top view In its fully down/open state, the two 2.5 inch (5cm) tall by 3.5 inch (9.5cm) deep Gripper paddles (each with 0.5cm foam pads on the inside) are 8.5 inches (21.5cm) apart and ride 1 inch (2.3cm) off the floor. The paddles extend out fr[...]

Overview 4 In transition from the fully down/open position to their up/closed state, the Gripper paddles close together horizontally until they pinch an object or close on themselves. At that point, the entire Bar and Gripper Assembly rises up vertically—with or without an object in its grasp. Under software control, the Gripper then rises to a s[...]

Gripper & Experimenter’s Module 7 3. Installation lease read through this chapter carefully before you attempt to attach the Gripper & Experimenter’s Module to your Pioneer 1 Mobile Robot. If for any reason you do not wish to perform the work yourself, contact RWI and make arrangements to have the assembly installed at the factory. On t[...]

Installation 8 Figure 2-1. Pioneer 1 microcontroller card 3.1.3 Step 3: Replace the PSOS EPROM Locate the EPROM/SRAM socket (Figure 2-2) on the microcontroller card and note that the Pin 1 locator notch on its case is towards the outer edge of the board—you’ll want to similarly position the new PSOS EPROM. Pry or pull out the socketed EPROM chi[...]

Gripper & Experimenter’s Module 9 press carefully, but firmly down on the chip with your thumb or forefinger to seat it tightly in the socket. 3.1.4 Step 4 Reattach Microcontroller to Console By reversing the procedures you took in Step 2 and using the same tools and screws, reattach the Pioneer microcontroller to the Console top plate. Set t[...]

Installation 10 3.1.8 Step 8 Re-Attach the Console Cables Carefully handling the Console top plate with attached microcontroller by its edges, reattach the various cables, front and back. Although the order is not critical, for convenience we recommend attaching the front cables first  the sonar and drive (left and right) cables. Then, to the so[...]

Gripper & Experimenter’s Module 11 4. Gripper Operation and Programming he Pioneer Gripper comes fully integrated with the robot’s systems and software. The latest versions of PSOS (4.2+) contains support for direct control of the Pioneer’s onboard I/O that run the Gripper functions, as well as state-based software control routines that m[...]

Gripper Operation and Programming 12 4.3 Gripper I/O The Gripper’s single drive motor is controlled through two digital output lines and under control of the microcontroller CPU: Output port OD0 controls the direction of rotation and OD1 enables/disables the motor. The act of gripping and raising objects is mechanical and dependent on the Gripper[...]

Gripper & Experimenter’s Module 13 The revised PSOS 4.2 (and later) sfCOMDIGOUT command has a two-byte argument: The high byte is a mask of those output bits you want to change, and the low byte is the bit pattern for the bits to change. This way, you don’t need to know the state of the port(s) you want to change; just the state in which yo[...]

Experimenter’s Module esides hosting the Gripper, the Experimenter’s Module brings several new features to the Pioneer 1 Mobile Robot, and provides you with a platform for adding your own robotics options and features (Figure 4-1): Easy access to Pioneer digital I/O, A/D, and timer functions Speaker w[...]

Experimenter’s Module 16 Note also that the Nose (N) 16-pin and the General (G) 26-pin I/O connectors are numbered odd pins on top and even pins on the bottom; not top, left to right, then bottom left to right. The pinouts for the Nose connector, for example, are: 1 3 5 7 9 11 13 15 2468 1 0 1 2 1 4 1 6 Table 4-1. Pioneer I/O ports and connection[...]

Gripper & Experimenter’s Module 17 5.1.1 Digin: Self-Test You may investigate the operation of the digital input and output ports through their PSOS self-test modes. After starting up your Pioneer, press the black Function button once to enable self-test mode. The LCD message should now display: BREAK, Boot to r eturn vv.vV* indicating that P[...]

Experimenter’s Module 18 5.2 Programming the Digital I/O Ports Use the sfCOMDIGOUT PSOS command and the related Saphira convenience command to manage the various digital output ports. They are described in detail in the previous chapter. (PAI and P-LOGO support similar commands, too.) For example, to turn the right LED on, use: sfRobotCom2Bytes(s[...]

Gripper & Experimenter’s Module 19 6. Maintenance & Repair he Pioneer Gripper is built to last a lifetime and requires little maintenance. 6.1 Drive Lubrication An occasional drop or two of oil on the guide rails is a very good idea. Place some thin, household oil on a Q-Tip or similar applicator, and rub along the rails. Then start up th[...]
