Chapter 1 Quick Start
Overview
Thank you for using the Bolt™ Jr+ Cinebot™ rig from Mark Roberts
Motion Control (MRMC). Bolt Jr+ is designed for reliable day-in, day-out
use in professional studio and Outside Broadcast environments. It has a
small, lightweight robotic arm which can be used either as camera rig or
model mover. There are two versions of Bolt Jr+:
Bolt™ Jr+ on Pedestal has a
stationary base which you either
hold down with weights or, for
more permanent installations,
attach to the floor.
Bolt™ Jr+ on Track has a base
designed for moving along
Precision Track, which can be
bolted to the ground and can
also be held down with weights
at temporary locations. It has
removable trolley wheels for
moving between sets.

Safety procedures for using industrial robots,
including high speed track
Note that the words Robot and Rig are completely interchangeable and
identical in meaning, for the purposes of this document.
Motion Control rigs are potentially dangerous. It is important that you
and everyone else on the set understand the safety notes on the following
pages in order to stay safe.
You should use this document in addition to the normal Safety Manual
instructions that are applicable to all motion control rigs, such as Milos.
This section emphasises the safety concerns that are especially important
around high-speed, high-acceleration, industrial-grade robots which can
cause severe injuries, such as Bolt Jr+.
Unlike traditional motion control equipment, Bolt Jr+ can get
to maximum speed in the blink of an eye - too fast for someone
to be able to quickly move out of the way.
If you are using Bolt Jr+ on Track, you need to take extra steps
during installation and use due to the additional risks involved
in using track. See the separate Precision Track Quick Start
Guide for information on laying the track, securing it to the
floor, and mounting Bolt Jr+ onto it. The notes given below for
track users are marked with this symbol: .
It is ultimately the operator of the rig who is responsible for
the safe use of the equipment so never bypass any of the safety
points listed here.
No one other than a highly trained operator should use the
robot, no matter how simple it looks or is.
This document is for the use of robots for carrying cameras or
props, not people. Additional safety steps should be taken prior
to using a rig to carry people.

Assessing a site
Before setting up Bolt Jr+ you need to assess the site, paying particular
attention to the following points:
Is the ground or floor firm enough and level enough? You
might have to use boards or bricks to create a level surface. The
surface needs to be strong enough to take the weight of Bolt
Jr+ itself (390kg) plus the weight of the track (95 kg per
section) or for Bolt Jr+ on Pedestal 264kg plus weights 280kg
of weights (2x140kg).
Does the site have access? You need to make sure you can
either push Bolt Jr+ into position on its wheels or carry it there
using a pallet truck or forklift.
Does the site have a power source with sufficient capacity for
the robot and the correct mains voltage?
– Bolt Jr+ on Track requires a 230V, single-phase power
supply via 2x16A power connectors.
– Bolt Jr+ on Pedestal requires a 230V, single-phase power
supply via a 16Apower connector.
– The computer stack that controls Bolt Jr+ (that is, the
desktop computer and the power supply brick for the
RT-14 interface box) are auto-switching and can run on
120-240 Volts AC.
Does the site have unusual environmental attributes that
require specialised protection from extreme temperatures,
humidity, rain, or dust?
Installation safety
Due to the large mass of the rigs and the accelerations they
achieve it is important that they are securely mounted, with the
recommended plates and bolts to a secure and concrete floor.
When using track, ensure that it is properly bolted to the floor.
If bolting the track is not possible, use 140kg of counter
weights on each corner of the track totalling to 560kg.
Make sure there is plenty of clearance around the length of the
track for the trailing cables of the rig to slide along the floor.

Ensure that they are not mounted in such a way so that they
can catch on the track or robot as it moves along the full
length.
Ensure the floor can support the load and the stresses (see
above).
Ensure the power supply is properly earthed (grounded) and of
the correct voltage (see above).
If the rig is mounted to something other than the floor then
the mount should be heavy and strong enough to take the
forces and not move or fall over during sudden starts and
stops. Use the recommended minimum thickness steel plates.
Check with MRMC if you are unsure of the exact requirements
for your robot.
Check that all cables are securely fixed and are not going to
catch during motion.
Ensure the camera, lens, focus motor, accessories, power
supplies/batteries, etc. are all very securely mounted and will
not come off during sudden motions, to become lethal
missiles.
Ensure all safety accessories are securely attached and in
working order, including emergency stops, safety sensors, etc.
Clearly mark the area around the robot in which no persons
are allowed to enter. As a bare minimum, use brightly marked
tape on the floor, outside the reach of the robot, to indicate the
“No Go Zone”. Ideally, use physical safety barriers, and light
guards/curtains.
Keep stands, lights and accessories out of the No Go Zone, if
possible. If not possible then try to take as much care with their
positioning and the motion of the rig, as if they were a person.
Remember a light, accidentally hit at high speed by the robot,
can be just as dangerous to someone standing outside the No
Go Zone as the robot is to someone standing in the zone.
Where physical safety barriers are impractical, light guards
should be used or similar alternatives such as laser scanners, to
stop anyone entering the No Go Zone during motion.

Ideally have the robot surrounded on all four sides by a safety
barrier, but where that is not practical, ensure that the
maximum number of sides feasible are closed off, and that any
person having to stand within reach of the robot is located as
far away as possible for the shot.
Never let anyone cross the robot’s track when the track motor
is powered up. In fact, it is a good idea to get into the routine of
walking around the track instead of over it so that you don’t
cross the track out of habit when the track motor is powered
up.

Software setup
Always ensure you have the right configuration for the robot
you are using, such as maximum axis speeds and accelerations.
Prior to running moves, enter in and keep to a minimum all
software axis and Cartesian limits. For example if the main axis
only needs to travel +/-40 degrees then reduce the limit to +/
-40 degrees even though it could do +/-180 degrees. This keeps
the likelihood of operator or software errors to a minimum.
Also check the Cartesian speed and acceleration limits are set
to reasonable values.
Operational safety
Do not use around flammable gas. All electrical equipment can
generate sparks that can ignite flammable gas.
Keep the equipment dry. The system has not been made
weatherproof. Do not use with wet hands.
Always run moves only when standing within easy reach of the
emergency stop.
Always tell the production
company and the crew to keep
away from the robot and not
approach it when any of its red
lights are on which indicates it is
powered up. Have them sign the
appropriate safety documents
and disclaimers to ensure they
understand this and are
indemnifying MRMC if
anything happens.
Always loudly and clearly indicate to others when the rig is
about to move. Shout “Rig Moving!” if no other means exists.
When using track motion always have someone keep an eye on
the trailing rig cables to ensure they don’t get caught on
anything or anyone.
Always ensure the rig is disabled when someone has to enter
the No Go Zone.

Bolt™ Jr+ Quick Start Guide

Always run any move or adjusted move slowly at first to check
the motion. Even if you have checked the move previously, if
you make a minor change to it then you need to recheck it.
Keep the software in “slow mode” unless the move has been
tested and is now specifically doing a high speed pass.
In the event that a person or Actor has to be within the no-go
zone during a move (hand model etc.) ensure that they are
fully briefed on the safety requirements and that they know not
to change their position or do anything other than the
rehearsed moves without fully warning the operator. Any such
person is to have a clear escape route to allow them to move
safely away from the robot.
During use, repeatedly check the rig mounting points, cables,
camera mount, accessories etc. to ensure nothing has, or is,
working its way loose.
Never bypass any safety hardware or software.

1. Use the jack screws on the castor wheels to lift the base high enough
to insert each of the weight plates on either side of the Bolt Jr+ Base
lining up the screw cavities.
2. Lower the base close to the wing but not quite resting on it, close
enough for the two retaining bolts to reach the wings through the
base.

3. Lower the base completely so it is resting on both wings. Secure the
weight plates using the 2xM10 screws on either plate. The screws
should be wedged to the ground to secure the weight plate
completely.
4. At this point, you can remove the castor wheels.
5. Attach the bridges with two weight plates on one side using the
4xM10 screws that attach to the weight plates and 2xM10 screws
that attach to the pedestal base.
Repeat this to secure the bridge on the opposite side.

6. Put the weights onto the wings. Bolt Jr+ requires 2 boxes of weights
— one on each side. Each box contains 140kg of weights (7 × 20kg).
Hint
You can use a pallet truck to move Bolt Jr+ without removing the
wings and bridges if you want, as long as you take the weights off
first.

Mounting the Castor Wheels (Bolt™ Jr+ On
Pedestal)
If you need to move the Bolt Jr+ on Pedestal around, use the following
procedure to mount the castor wheels:
1. Remove the bridge plates.
2. Slide one castor wheel into the base ensuring that edge of the plate
in the wheel assembly is inserted in the slot in the base.

Mounting the Optional Riser(s)
Bolt Jr+ can include optional risers if higher arm reach is required. These
come in two sizes: 150mm and 300mm; either or both of them can be
used. Use the following instructions to mount any riser on the pedestal:
1. Remove the arm from the base by unscrewing the 4xM12 screws
and using a gantry hoist to lift the arm.
2. Remove the mounting plate from the base by unscrewing the 3xM12
screws.
3. Lower the riser on the base aligning the three screw cavities and
tighten the 3xM12 screws to secure the riser on the base.
4. Mount the mounting plate on the riser using 3xM12 screws.
5. Carefully lower the arm on the base aligning the screw cavities on
the mounting plate and those on the robot arm. Screw 4xM12 to
secure the arm on the base.

Note
If you are using the 300mm riser, anchor the Bolt Jr+ on Pedestal
down to the floor. Refer to the next section for details.
Limitations when using weights
If you are using weights, reduce the top-speed by 50% when you have
the 300mm riser added. With the small riser, reduce the speed by
25%. If you are using both the risers together, then the rig can only
be used at slow speeds.

Anchoring Bolt™ Jr+ on Pedestal to the floor
If you are setting up Bolt Jr+ on Pedestal in a permanent (or
semi-permanent) location, you can anchor the pedestal to the floor as an
alternative to holding it down with weights. The following procedure tells
you how to anchor the pedestal to a concrete floor.
1. Wheel the Bolt Jr+ on Pedestal to the spot where you want to bolt it
to the ground and lower it using the jacks on the castor wheels.
2. At one corner of the pedestal, use the hole to draw a circle on the
concrete with a pencil, to mark the position of the hole. You can use
either hole.
Repeat for the other three corners of the pedestal.
3. Temporarily remove Bolt Jr+ on Pedestal (jack the castor wheels up)
and at the four circles that you have drawn, draw cross centred on
the circle, to help you precisely locate the drill bit.
4. On the 15mm diameter drill bit, put tape around the bit 5 cm from
the tip. This will help you gauge the depth of the hole in the next
step.
5. At one of the corner circles, drill a hole 5 cm deep into the concrete,
centred on the cross. When the tape on the drill bit reaches the floor,
drilling is complete.
Repeat for the other three corners.
6. Clean the four holes.
